Super Grub2 Disk 2.02s4 released

Super Grub2 Disk 2.02s4 stable 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 stable release

The former Super Grub2 Disk stable release was 2.00s3 version and released on May 2015 (10 months ago) . New features or changes since previous stable version are:

  • Using upstream grub-2.02-beta3 tag as the new base for Super Grub2 Disk’s grub.
    If Super Grub2 Disk 2.02s3 let you boot into your OS but Super Grub2 Disk 2.02s4 does not let you boot into your OS please report it so that we can report it back to the grub team which tries to release a Grub 2.02 stable release.
  • Major improvement in Windows OS detection (based on BCD) Windows Vista, 7, …
    That means that even if Windows 7 is alone in the hard disk (with no GNU/Linux) it will now be detected and you will be able to boot it if the partition boot record is ok. The fix was trivial, take into account that ntfs is case sensitive but, somehow, not enough people had complained about it. So, please, if something it’s not working as expected report it.
  • Major improvement in Windows OS detection (based on ntldr) Windows XP, 2000, …
    Same explanation as per Windows 7 but applied to Windows XP.

We are going to see which are the complete Super Grub2 Disk features with a demo video, where you can download it, the thank you – hall of fame and some thoughts about the Super Grub2 Disk development.

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, x86_64-efi) (ISO)
  • EFI x86_64 standalone version (EFI)
  • Additional Floppy, CD and USB in one download (ISO)
    • i386-pc
    • x86_64-efi

Known bugs

  • Non English translations are not completed
  • Enable all native disk drivers *experimental* crashes Virtualbox randomly

Supported Media

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


Recommended download (Floppy, CD & USB in one) (Valid for i386, x86_64, and x86_64-efi):

About other downloads. As this is the first time I develop Super Grub2 Disk out of source code (well, probably not the first time, but the first time in ages) I have not been able to build these other downloads: coreboot, i386-efi, i386-pc, ieee1275, x86_64-efi, standalone coreboot, standalone i386-efi, standalone ieee1275. Help is welcome on this subject.

Changelog (since former 2.00s2 stable release)

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
  • New option: ‘Disks and Partitions (Chainload)’ adapted from Smx work
  • Many files were rewritten so that they only loop between devices that actually need to be searched into.
    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:

  • bfree (Niall Wash): For his work in rethinking how Super Grub2 Disk grub script might be rewritten although we never used that code. For adding code for EFI chainloader, helping on building and testing Super Grub2 Disk EFI releases.
  • Jordan_U (Jordan Uggla) (jordan.uggla AT gmail DOT com): For his work in rewriting Lua Super Grub2 Disk into new Grub2 scripting. Also for his work in translation system based on gettext and po. And also I want to thank him for all this work in Super Grub2 Disk in many many ways.
  • nox (Juergen Lock) (nox AT freebsd DOT org): For his work in fixing *BSD boot entries and helping adding new *BSD boot entries and testing.
  • Smx (Stefano): For his Mac OS X / Darwin boot fixes and testing. He has also worked in redesigning some of the menues and probably his work will be included in next Super Grub2 Disk versions. He has also worked in a keyboard selection menu on his own too. That will be also included in next versions.

The person who writes this article is adrian15 and is proud of being responsible among other things for the rewriting of options as if they were libraries. And also for the User Interface (UI) complete redesign.

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 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 2016. It’s a shame because last time I predicted July 2015. But, well, I don’t want to maintain many forks myself. That’s why I want to contribute some of these subprojects (E.g. UEFI support on Debian Live) to Debian properly and that takes some time.

One thought on “Super Grub2 Disk 2.02s4 released

  1. Hello,

    Thanks a lot for Super Grub Disk 2, it help me repair my multiboot system a lot of time without reinstalling everything.

    I recently downloaded rescatux and installed it on my multisystem (thanks to YUMI) USB key (boot it if your PC doesn’t do anything) so i need to test it but it seems full of promises.

    Thanks again for your work !
    Frank from France
