Super Grub2 Disk 2.06s1-beta2 released

Super Grub2 Disk 2.06s1-beta2 is here.

Super GRUB2 Disk is a live cd that helps you to boot into most any Operating System (OS) even if you cannot boot into it by normal means.

A new beta release

This new release removes the April Fools Day prank, adds a new Docker build system and has many other minimal improvements. Finally this new release is based on Grub 2.06 instead of the older Grub 2.04

Please do not forget to read our howtos so that you can have step by step guides (how to make a cdrom or an usb, how to boot from it, etc) on how to use Super Grub2 Disk and, if needed, Rescatux.

Here there is a little video tour in order to discover most of Super Grub2 Disk options. The rest of the options you will have to discover them by yourself.


Most of the features here will let you boot into your Operating Systems. The rest of the options will improve the Super Grub2 Disk operating systems autodetecting (enable RAID, LVM, etc.) or will deal with minor aspects of the user interface (Colours, language, etc.).

Support for different hardware platforms

Before this release we only had the hybrid version aimed at regular pcs. Now with the upcoming new EFI based machines you have the EFI standalone versions among others. What we don’t support is booting when secure boot is enabled.

  • Most any PC thanks to hybrid version (i386, x86_64, i386-efi, x86_64-efi) (ISO)
  • EFI x86_64 standalone version (EFI)
  • EFI i386 standalone version (EFI)
  • Additional Floppy, CD and USB in one download (ISO)
    • i386-pc
    • i386-efi
    • x86_64-efi

Known bugs

  • Non English translations are not completed

Supported Media

  • Compact Disk – Read Only Memory (CD-ROM) / DVD
  • Universal Serial Bus (USB) devices
  • Floppy (1.98s1 version only)

NOTE:   The hybrid version should work in most any machine you might have. Please download that version.

Non scientific machine names Description
Oldie x86   These are very old machines that only have 32-bit processors. Their supported architecture for boot is i386.
Oldie 64bit   These are old machines, usually from 2010 year or before. They have 64-bit processors. Their supported architectures for boot are: i386 and x86_64.
UEFI 64bit   These are new machines, usually from 2011 year or after. They have 64-bit processors. Their supported architecture for boot is: x86_64-efi. If you enable CSM (also known as legacy boot) support on them they also support i386 and x86_64.
UEFI 32bit   These are new machines, usually from 2011 year or after. They are very rare. They have either 64-bit processors or 32-bit processors but somehow boot initially in 32-bit mode. Their supported architecture for boot is: i386-efi. I highly doubt you can enable CSM support on these machines.

NOTE:   The hybrid version should work in most any machine you might have. Please download that version.

Changes since 2.04s2-beta2 version:

  • Update supergrub-mkcommon functions to be able to build gpt based images.
  • menulstdetect does not need to use regexp module.
  • Make sure to use regexp on autoiso. Fixes #46 .

  • Show when each menu is build with its date. Fixes #44 .
  • Make sure cfg files do not have execution bit
  • Disk and partitions: Handle empty label properly.
  • Merge pull request #49 from mk-pmb/uncontroversial_indentation_fixes
  • New Docker build system
  • grub-build-config: Switch to Grub 2.06 version.
  • April Fools Day prank was removed.
  • Docker: Use PREVIOUS_VERSION as the environment variable when the docker is run.
  • Docker: Make sure that devices work seamlessly.
  • Bump version to 2.06s1-beta2.
  • mk-pmb (5):

  • Zip USB based images

  • Use grub-2.04 upstream grub2 tag

Changes since 2.02s9 version:

  • (Devel) File hashes generation has been rewritten to work from the single supergrub-mkcommon generate_filename_hashes function
  • (Devel) Now MD5SUMS, SHA1SUMS and SHA256SUMS files are generated as part of the official build.

    2 Disk releases.

Changes since 2.02s4 version:

  • Stop trying to chainload devices under UEFI and improve the help people get in the case of a platform mismatch
  • (Devel) Properly support source based built grub-mkfont binary.
  • New options were added to chainload directly either /ntldr or /bootmgr thanks to ntldr command. They only work in BIOS mode.

Changes since 2.02s3 version:

  • Using upstream grub-2.02-beta3 tag as the new base for Super Grub2 Disk’s grub.
  • Major improvement in Windows OS detection (based on BCD) Windows Vista, 7, …
  • Major improvement in Windows OS detection (based on ntldr) Windows XP, 2000, …

Changes since 2.02s2 beta 1 version:

  • (Devel) grub-mkstandalone was deleted because we no longer use it
  • Updated (and added) Copyright notices for 2015

    This enhacement will make Super Grub2 Disk faster.
  • Remove Super Grub2 Disk own devices from search by default. Added an option to be able to enable/disable the Super Grub2 Disk own devices search.

2.02s2 beta 1 changelog:

  • Updated grub 2.02 build to commit: 8e5bc2f4d3767485e729ed96ea943570d1cb1e45
  • Updated documentation for building Super Grub2 Disk
  • Improvement on upstream grub (d29259b134257458a98c1ddc05d2a36c677ded37 – test: do not stop after first file test or closing bracket) will probably make Super Grub2 Disk run faster.
  • Added new grub build scripts so that Super Grub2 Disk uses its own built versions of grub and not the default system / distro / chroot one.
  • Ensure that Mac OS X entries are detected ok thanks to Users dir. This is because Grub2 needs to emulate Mac OS X kernel so that it’s detected as a proper boot device on Apple computers.
  • Thanks to upstream grub improvement now Super Grub2 Disk supports booting in EFI mode when booted from a USB device / hard disk. Actually SG2D was announced previously to boot from EFI from a USB device while it only booted from a cdrom.

2.02s1 beta 1 changelog:

  • Added new option: “Enable all native disk drivers” so that you can try to load: SATA, PATA and USB hard disks (and their partitions) as native disk drives. This is experimental.
  • Removed no longer needed options: “Enable USB” and “Enable PATA”.
  • “Search floppy” and “Search cdrom” options were moved into “Extra GRUB2 functionality menu”. At the same time “Extra Search functionality” menu was removed.
  • Added new straight-forward option: “Enable GRUB2’s RAID and LVM support”.
  • “List devices/partitions” was renamed to “Print devices/partitions”.
  • “Everything” option was renamed to “Detect and show boot methods”.
  • “Everything +” option was removed to avoid confusions.
  • Other minor improvements in the source code.
  • Updated translation files. Now most translations are pending.
  • Updated INSTALL instructions.

Finally you can check all the detailed changes at our GIT commits.

Thank you – Hall of fame

I want to thank in alphabetical order:

  • The upstream Grub crew. I’m subscribed to both help-grub and grub-devel and I admire the work you do there.
  • Necrosporus for his insistence on making Super Grub2 Disk smaller.

The person who writes this article is adrian15 .

And I cannot forget about thanking bTactic, the enterprise where I work at and that hosts our site.

Some thoughts about Super Grub2 Disk development

Super Grub2 Disk development ideas

I think we won’t improve Super Grub2 Disk too much. We will try to stick to official Grub2 stable releases. Unless a new feature that it’s not included in official Grub2 stable release is needed in order to give additional useful functionalities to Super Grub2 Disk.

I have added some scripts to Super Grub2 Disk build so that writing these pieces of news is more automatic and less prone to errors. Check them out in git repo as you will not find them in 2.02s8 source code.

Old idea: I don’t know when but I plan to readapt some scripts from os-prober. That will let us detect more operating systems. Not sure when though. I mean, it’s not something that worries me because it does not affect too many final users. But, well, it’s something new that I hadn’t thought about.

Again, please send us feedback on what you think it’s missing on Super Grub2 Disk.

Rescatux development

I want to focus on Rescatux development on the next months so that we have an stable release before the end of 2017. Now I need to finish adding UEFI features (most finished), fix the scripts that generate Rescatux source code (difficult) and write much documentation.

(adrian15 speaking)
