0.8.11 (?/?/2014):
1.0.5 (?/?/2020):
-----------------
- Fixed typos and minor formatting issues in man pages
- Changed number of columns in type code output ("sgdisk -L" and equivalents
in gdisk and cgdisk) from 3 to 2, since some descriptions are long enough
that they're ambiguous with three columns.
1.0.4 (7/5/2018):
-----------------
- Added some explicit copy constructors and made some other tweaks to avoid
compiler warnings.
- The macOS binary for sgdisk is now a pure 64-bit build; I'm no longer
supporting 32-bit builds of sgdisk. The gdisk and cgdisk binaries remain
"fat" 32-/64-bit builds. The reason for dropping the 32-bit support from
sgdisk is that I've re-built my macOS development system, and I had
trouble building a "fat" binary with the fresh install of the popt
libraries upon which sgdisk relies. 32-bit support for the other binaries
is now officially deprecated, too.
- Added search feature to partition type list functions ("L" on main menu of
gdisk and "L" when entered in response to the "Hex code or GUID" prompt in
gdisk and sgdisk). This feature filters the partition type list to those
which include the search term in their GPT fdisk descriptions. For
instance, typing "Linux" shows only partitions with "Linux" in their
descriptions. Note that the search/filter is case-sensitive. If <Enter> is
pressed, no filter is applied.
- Change to Makefile.mac to use standard libncurses rather than a 3rd-party
version; should help with cgdisk compatibility.
- Minor bug fix in alignment of internal data structures.
- Minor bug fix in handling of damaged disks. Also, GPT fdisk now reports
more information on what data structures are damaged when a damaged disk
is detected.
- Added type code for Apple APFS (7C3457EF-0000-11AA-AA11-00306543ECAC,
0xaf0a).
- Added type code for Atari TOS basic data (0xa200,
734E5AFE-F61A-11E6-BC64-92361F002671).
- Added type codes for Linux dm-crypt (0x8308,
7FFEC5C9-2D00-49B7-8941-3EA10A5586B7) and LUKS (0x8309,
CA7D7CCB-63ED-4C53-861C-1742536059CC) partitions.
- Added 18 Ceph partition type codes.
- Added 52 (yes, 52!) Android partition type codes.
- Changed "Creating new GPT entries" message to read "Creating new
GPT entries in memory" because the latter is clearer, particularly when
using sgdisk with a non-destructive option, like "-p".
1.0.3 (7/27/2017):
------------------
- Fixed a major bug that caused invalid partition tables to be generated
when creating a new partition table (that is, partitioning a blank disk or
converting from MBR).
1.0.2 (7/26/2017):
------------------
- On Linux, the p/-p/--print command now shows the disk's model name, as
reported in /sys/block/sda/device/model (or equivalent filenames for other
disks). This feature does not yet work on other platforms, on which the
model name line is omitted from the output. This line is also not shown
when accessing disk image files, even on Linux.
- GPT fdisk can now report both the physical and logical sector sizes of
disks, but only on 2.6.32 and later Linux kernels. The verify feature now
uses the larger of the set alignment and physical/logical block sizes for
testing alignment, and setting alignment to something other than an exact
multiple of the ratio of the physical to logical block size results in a
warning.
- Addition of new verification checks, mostly (but not exclusively) related
to the new j/-j/--move-main-table option.
- Added new option: 'j' on the experts' menu in gdisk;
'-j/--move-main-table={sector}' in sgdisk. This option enables relocating
the main partition table from sector 2 (the default location) to somewhere
else on the disk. The main reason I know of to do this is if the disk is
to be used with a system-on-chip (SoC) computer, some of which require the
boot loader to be located at sector 2. If you pass this option the default
value of 2, it has the effect of reducing the padding placed between the
main partition table and the first usable sector value created by the
Linux fdisk tool.
- Updated man pages with new recommendations for ESP and BIOS Boot Partition
sizes.
- Added four type codes (AF06 through AF09) for Apple SoftRAID (Status,
Scratch, Volume, and Cache).
- Added two type codes for the Open Network Install Environment (ONIE):
0xe100 (7412F7D5-A156-4B13-81DC-867174929325) and 0xe101
(D4E6E2CD-4469-46F3-B5CB-1BFF57AFC149).
- Added thirteen type codes for Android partitions (0xa000 through
0xa00c).
- Added type code for QNX6 (aka QNX Power-Safe) filesystem: 0xb300, for
CEF5A9AD-73BC-4601-89F3-CDEEEEE321A1.
- Removed stray debug message ("REALLY setting name!") from sgdisk,
when setting new name via -c option.
1.0.1 (10/18/2015):
-------------------
- Created uninstall-fixparts and uninstall-gdisk scripts for OS X. As the
names imply, these scripts remove the files installed by the fixparts and
gdisk packages, respectively.
- Fixed bug that caused -N/--largest-new option to sgdisk to fail when
fed a "0" option.
- Fixed bug that caused input glitches in EFI version of gdisk.
- Fixed bug that caused sgdisk to not return an appropriate error code
when it encountered a write error when saving changes.
- Fixed bug that caused cgdisk's "Info" display to under-report the
partition's size by one sector.
- OS X 10.11 includes new security features that prevent GPT fdisk from
working unless these features are disabled. To do so, you must boot to a
Recovery HD system, open a Terminal, type "csrutil disable", and reboot
into the normal system. You can re-enable the security features by
repeating the process, but specify "enable" rather than "disable". I've
added a message pointing users to a Web page explaining how to disable
this feature when gdisk detects that it can't write to the disk under OS
X. If you know of a way around this (including code changes to gdisk),
please contact me.
- I've updated the OS X installation location from the Unix-standard
/usr/sbin (and related locations for documentation) to /usr/local/bin
(and related locations for documentation). This is Just Plain Crazy from
a Unix point of view, but Apple has to be Apple and do things just a
little bit differently.
- I've updated my OS X environment to OS X 10.11 and LLVM 7.0.0. This has
also meant installing fresh versions of popt and ncurses from MacPorts,
which may require upgrading popt to get sgdisk working on some systems.
(gdisk, cgdisk, and fixparts should continue to work normally on all
systems.) The OS X binaries are now "fat" (32- and 64-bit) versions,
which should have no noticeable effect unless you have a Mac with broken
32-bit support, in which case the binaries will now work.
- Changed the default name of 0xab00 partitions from "Apple boot" to
"Recovery HD", since the latter is the name that Apple gives these
partitions. Also, I discovered through painful experience that OS X
flakes out and won't boot if the name is something other than "Recovery
HD", so it really has to have the right name!
- Changed the OpenBSD type codes (0xa600 and 0xa601): 0xa600 is now
824CC7A0-36A8-11E3-890A-952519AD3F61 (OpenBSD disklabel) and 0xa601 is
now gone. Previously, 0xa600 was 516E7CB4-6ECF-11D6-8FF8-00022D09712B, a
duplicate of the FreeBSD disklabel, and 0xa601 was
824CC7A0-36A8-11E3-890A-952519AD3F61. OpenBSD is now officially
supporting 824CC7A0-36A8-11E3-890A-952519AD3F61 as a disklabel type,
though. It's unclear what, if anything, OpenBSD will use for
non-disklabel type codes at the moment.
- Added GUID 0311FC50-01CA-4725-AD77-9ADBB20ACE98 (0xbc00) for
Acronis Secure Zone backup partitions.
- Fixed bug that caused random crashes on ppc64el systems (and perhaps
others).
- Added GUID C91818F9-8025-47AF-89D2-F030D7000C2C (0x3900) for Plan 9.
- Added GUID 69DAD710-2CE4-4E3C-B16C-21A1D49ABED3 (0x8307) for 32-bit ARM
Linux root (/) partition, as per the Freedesktop.org Discoverable
Partition Spec
(http://www.freedesktop.org/wiki/Specifications/DiscoverablePartitionsSpec/).
- Edited man pages to clarify that default alignment is to 1MiB boundaries;
this translates to 2048 sectors on disks with 512-byte sectors, but it
will be something else on disks with other sector sizes.
- Changed behavior of -z/--zap and -Z/--zap-all options to sgdisk so that
if a subsequent command causes changes, they'll be written to disk.
Previously, doing something like "sgdisk --zap-all --clear /dev/sdd"
would wipe the disk but not create a partition table; to create a blank
table you'd need to do "sgdisk --zap-all --clear --mbrtogpt /dev/sdd",
which is a bit odd and counter-intuitive, to the point of arguably being
a bug.
1.0.0 (3/16/2015):
------------------
- I'm now building a binary package of gdisk_x64.efi, using the UEFI GPT
fdisk package.
- Added partition type for OpenBSD data
(824CC7A0-36A8-11E3-890A-952519AD3F61/0xa601). Also mapped 0xa600 to the
FreeBSD disklabel type code (516E7CB4-6ECF-11D6-8FF8-00022D09712B). I'm
not sure that's 100% correct, but since I can't find references to an
OpenBSD disklabel GPT type code, it seems the best choice at the moment.
- Added partition type for Windows Storage Spaces
(E75CAF8F-F680-4CEE-AFA3-B001E56EFC2D/0x4202)
- Added -O/--print-mbr option to sgdisk, enabling easier display of MBR
data structures without invoking gdisk.
- Updated warning message: "EBR describes a logical partition" now reads
"EBR points to an EBR," which is more technically correct.
- Altered warning displayed when run from Windows on non-GPT disk, because
Windows on UEFI-based systems is becoming more common.
- Fixed spurious "1" return value in gdisk.
- Small code changes to support compilation as EFI application with the
UEFI GPT fdisk library

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>

but WITHOUT ANY WARRANTY; without even the implied warranty of

You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General

README for EFI version of GPT fdisk
===================================
GPT fdisk for EFI is a binary build of gdisk to run as a pre-boot EFI
application. It's OS-independent and may be used to check or recover
partition tables before installing or booting an OS. It may be used to
overcome boot problems caused by partition table damage or to prepare a
partition table prior to installing an OS.
Installing GPT fdisk for EFI
----------------------------
The contents of this archive are:
- COPYING -- The GNU GPL
- gdisk.html -- The gdisk man page, in HTML form
- gdisk_x64.efi -- The gdisk binary, built for EFI (x86-64 CPU)
- NEWS -- The GPT fdisk changelog
- README-efi.txt -- This file
- refind.cer -- The rEFInd public key, .cer (DER) form
- refind.crt -- The rEFInd public key, .crt form
The gdisk_x64.efi binary included here is built using the UEFI GPT fdisk
library (https://sourceforge.net/p/uefigptfdisk/), which is a beta-level
partial C++ library for UEFI. To use it, you must copy it to your EFI
System Partition (ESP) or some other EFI-accessible location. Under Linux,
the ESP is usually one of the first two or three partitions on /dev/sda.
Under OS X, it's usually the first partition on /dev/disk0 (that is,
/dev/disk0s1). Under Windows, you can mount it to S: by typing "mountvol S:
/S" in an Administrator command prompt. In any of these cases, the
recommended location for gdisk_x64.efi is the EFI/tools directory on the
ESP. In that location, my rEFInd boot manager will detect the gdisk binary
and create a menu option to launch it. If you don't use rEFInd, you can
launch the program using an EFI shell, register it as a boot program with
your firmware, or configure your boot manager (GRUB, gummiboot, etc.) to
launch it. Note that boot LOADERS, such as SYSLINUX and ELILO, can't launch
gdisk.
Alternatively, you can create a USB flash drive that will launch gdisk when
you boot from it. To do so, create a FAT filesystem on a partition on a USB
flash drive and copy gdisk_x64.efi to it as EFI/BOOT/bootx64.efi. (You'll
need to create the EFI/BOOT directory.) Some systems may require the FAT
filesystem to be flagged as an ESP (with a type code of EF00 in gdisk). You
can use your firmware's built-in boot manager to boot from the USB flash
drive. Some such boot managers present two options for booting USB flash
drives. If yours does this, select the option that includes the string
"UEFI" in the description.
The gdisk_x64.efi binary is signed with the rEFInd Secure Boot key. Thus,
if you're launching a rEFInd that I've compiled and distributed myself,
gdisk should launch, too. If you're *NOT* running rEFInd but ARE using
Shim, you'll need to add the refind.cer file to your MOK list by using the
MokManager utility. If you're using Secure Boot and you've signed rEFInd
yourself, you'll need to sign gdisk_x64.efi yourself, too. Note that the
rEFInd PPA distributes unsigned binaries and signs them with a local key
stored in /etc/refind/keys. To copy and sign the gdisk_x64.efi binary, you
should type (as root or using sudo):
sbsign --key /etc/refind.d/keys/refind_local.key \
--cert /etc/refind.d/keys/refind.crt \
--output /boot/efi/EFI/tooks/gdisk_x64.efi ./gdisk_x64.efi
This command assumes you have local rEFInd keys stored in the locations
created by the rEFInd installation script. Substitute your own keys if
you've built them in some other way. Some distributions don't provide the
sbsign binary, so you may need to build it yourself. See the following page
for details:
https://git.kernel.org/cgit/linux/kernel/git/jejb/sbsigntools.git/
Note that you do *NOT* need to sign gdisk if your computer doesn't use
Secure Boot or if you've disabled this feature.
Using gdisk for EFI
-------------------
The EFI version of gdisk is basically the same as using the Linux, OS X, or
other OS versions. One exception is that you do not specify a disk device
on the command line; gdisk for EFI instead displays a list of devices when
you launch and enables you to select one, as in:
List of hard disks found:
1: Disk EFI_HANDLE(3EB5DD98): 108423424 sectors, 51.7 GiB
Acpi(PNP0A03,0)/Pci(1|1)/Ata(Primary,Master)
2: Disk EFI_HANDLE(3EB58289): 105456768 sectors, 50.3 GiB
Acpi(PNP0A03,0)/Pci(D|0)?
Disk number (1-2): 2
Once you've selected your disk, it should operate in much the same way as
any other version of gdisk. (See the next section, though!) Some programs,
including my rEFInd boot manager, complain about the changed partition
table, even if you've made no changes. If you run into problems using other
programs or launching an OS immediately after running gdisk, reboot; that
should cause the firmware to re-load its partition table.
Caveats
-------
I've tested gdisk_x64.efi on several systems. It's worked fine for me on 4
of 6 computers (5 of 7, counting VirtualBox). Two systems gave me problems,
though:
* gdisk presented a never-ending list of options (as if receiving a
never-ending string of "?" or other unrecognized command characters) on a
2014 MacBook Air.
* A computer based on an Intel DG43NB motherboard rebooted as soon as I
launched gdisk.
Both computers have relatively old EFIs. (Despite its newness, the Mac has
a 1.10 EFI, as do all Macs, to the best of my knowledge.) Most of the
computers that worked had 2.31 EFIs, although one had a 2.10 EFI.
The bottom line is that I can't guarantee that this binary will work on all
computers. It's conceivable that recompiling gdisk with the latest version
of the UEFI GPT fdisk library will help. Also, I haven't compiled a 32-bit
version, so if you have a 32-bit EFI, you'll have to compile it yourself or
do without.

Change the sector alignment value. Disks with more logical sectors per

configurations, and many SSD devices, can suffer performance problems if
partitions are not aligned properly for their internal data structures. On
new disks, GPT fdisk attempts to align partitions on 2048\-sector (1MiB)
