Super Grub2 Disk 2.04rc1s1 beta 4 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 releases features new upstream grub 2.04rc1 which includes

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.).

2.02s2 beta 1 changelog:

- 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.

- 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.
