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.

(Devel) Added grub-build-004-make-check so that we ensure the build works
(Devel) Make sure linguas.sh is built when running ‘grub-build-002-clean-and-update’
(Devel) Updated upstream Super Grub2 Disk repo on documentation
(Devel) Move core supergrub menu under menus/sgd
(Devel) Use sg2d_directory as the base super grub2 disk directory variable
(Devel) New supergrub-sourcecode script that creates current git branch source code tar.gz
(Devel) New supergrub-all-zip-file script: Makes sure a zip file of everything is built.
(Devel) supergrub-meta-mkrescue: Build everything into releases directory in order to make source code more clean.
(Devel) New supergrub-official-release script: Build main files, source code and everything zip file from a single script in order to ease official Super Grub 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
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.
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.
While we wait for Rescatux to be rewritten, once again, so that it’s based on Debian 10 (Buster) its main program: Rescapp needs some love. Some testing. Some polishment.
So if you want to help Rescatux / Rescapp development and you happen to have either a:

A new stable release
The former Super Grub2 Disk stable release was 2.02s9 version and released on May 2017 (1 year and 6 months ago) . New features or changes since previous stable version are:
‘Enable all native disk drivers’ option was improved. It no longer crashes.
Now devices are cached and Super Grub2 Disk is faster
Modify sg2d_directory and sg2d_dev_name variables so that SG2D is more portable
Standalone images are no longer broken and show main menu

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.
While we wait for Rescatux to be rewritten, once again, so that it’s based on Debian 9 (Stretch) its main program: Rescapp needs some love. Some testing. Some polishment.
Rescapp program has been rewritten so that:
It no longer depends on SELinux
It depends on PyQT5 instead of the now obsolete PyQT4
That means that it can be built for recent versions of Ubuntu, packaged and put into a repo.
So if you want to help Rescatux / Rescapp development and you happen to have either a:
Torrent (Open the link the in browser and click on Download Torrent File Now)
Rescatux 0.51b3 size is about 640 Megabytes.
Some thoughts:
Boot Repair functionality has been removed from Rescatux. Many people, somehow, were using Boot Repair (by default) inside Rescatux while we don’t support it.
If you feel Rescapp does not cover all the Boot Repair functionality you can fill a bug for a RFE (Request for Enhacement).
Rescapp and chntpw are now installed from a Repo. It should be virtually identical to 0.41b1 release. If something doesn’t work as well as before please report a bug so that we can fix it.
This is the last build based on Debian 8 (Jessie).
Important notice:
If you want to use the UEFI options make sure you use DD or another equivalent tool (Rufus in ‘Direct image’ mode, usb imagewriter, etc.) to put Rescatux in your USB
If you want to use UEFI options make sure you boot your Rescatux device in UEFI mode
If you want to use Rescatux make sure you temporarly disable Secure Boot. Rescatux does not support booting in Secure Boot mode but it should be able to fix most of the UEFI Secure Boot problems if booted in Non Secure Boot mode.
More things I want to do before the stable release are:
Make clear that ‘Extra tools’ are not supported renaming them to ‘Extra tools (Non supported)’
Internal documentation updated
A new Rescatux website (Optional)
A new Rescatux tutorial video or videos (Optional)
Let’s hope it happens sooner than later.

Fixed bugs (0.32b1):
Networking detection improved (fallback to network-manager-gnome)
Bottom bar does not have a shorcut to a file manager as it’s a common practice in modern desktops. Fixed when falling back to LXDE.
Double-clicking on directories on desktop opens Iceweasel (Firefox fork) instead of a file manager. Fixed when falling back to LXDE.
Improvements (0.32b1):
Super Grub2 Disk is no longer included. That makes easier to put the ISO to USB devices thanks to standard multiboot tools which support Debian Live cds.
Rescapp UI has been redesigned
Every option is at hand at the first screen.
Rescapp options can be scrolled. That makes it easier to add new options without bothering on final design.
Run option screen buttons have been rearranged to make it easier to read.
RazorQT has been replaced by LXDE which seems more mature. LXQT will have to wait.
WICD has been replaced by network-manager-gnome. That makes easier to connect to wired and wireless networks.
It is no longer based on Debian Unstable (sid) branch.
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.
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
The former Super Grub2 Disk stable release was 2.02s9 version and released on May 2017 (6 months ago) . New features or changes since previous stable version are:
Modify sg2d_directory and sg2d_dev_name variables so that SG2D is more portable
‘Enable all native disk drivers’ option was improved. It no longer crashes.
Now devices are cached and Super Grub2 Disk is faster
Other minor improvements
Standalone images are no longer broken and show main menu
Super Grub2 Disk 2.02s5 – Detect and show boot methods in action
Chinese Super Grub2 Disk main menu
Chinese Super Grub2 Disk – Detect all Operating Systems
Finnish Super Grub2 Disk main menu
Finnish Super Grub2 Disk – Detect all Operating Systems
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.

Tour
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.
Features
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.).

If you want such builds drop a mail in the mailing list so that we aware of that need.
(Devel) Added grub-build-004-make-check so that we ensure the build works
(Devel) Make sure linguas.sh is built when running ‘grub-build-002-clean-and-update’
(Devel) Updated upstream Super Grub2 Disk repo on documentation
(Devel) Move core supergrub menu under menus/sgd
(Devel) Use sg2d_directory as the base super grub2 disk directory variable
(Devel) New supergrub-sourcecode script that creates current git branch source code tar.gz
(Devel) New supergrub-all-zip-file script: Makes sure a zip file of everything is built.
(Devel) supergrub-meta-mkrescue: Build everything into releases directory in order to make source code more clean.

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
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.
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.
Rescapp is the Rescatux main program. It is a nice wizard that helps you in your rescue tasks.
For the last few weeks I have been working on separating Rescapp from Rescatux.
That way Rescapp is an standalone program and can be used on other distros.
Rescatux build will be also be more elegant.
This is a source code release so it’s not aimed at final users.
It’s rather aimed at expert users and GNU/Linux distribution package maintainers. Despite the 0.51b1 version this is the first beta release of Rescapp so any feedback is welcome.
Finally you should note that Rescapp assumes that the user under you run Rescapp can run the sudo command without sudo asking for a password. So you might need to modify your sudoers file.
For the time being Rescapp and Rescatux will have the same version as their development is highly tied.
