Super Grub2 Disk 2.02s8 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 2.02s7 version and released on February 2017 (1 month ago) . New features or changes since previous stable version are:
- Updated grub 2.02 build to tag: 2.02~rc2 . This is the release candidate for final stable 2.02 upstream Grub release. Please use this build to give them (upstream Grub) feedback on this version. It’s advised to ask here before reporting to them so that we discard the bug being a Super Grub2 Disk specific one.
- Thanks to a Necrosporus suggestion now default theme starfield is no longer included. Images are now smaller. E.g. the hybrid image size it’s 19.3 MB while former version image size was 22 MB.
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.
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)
- Non English translations are not completed
- Enable all native disk drivers *experimental* crashes Virtualbox randomly
- 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, i386-efi and x86_64-efi):
EFI x86_64 standalone version:
EFI i386 standalone version:
CD & USB in one downloads:
- Super Grub2 Disk (Floppy, CD & USB in one) 2.02s8 [i386-pc] (ISO)[Mirror #1]

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. bfree has helped on this matter and with his help we might have those builds in next releases. If you want such builds drop a mail in the mailing list so that we aware of that need.
Everything (All binary releases and source code):

- (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
- 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:
- 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.
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.
