    Super Grub2 Disk 2.04s2-beta2 released

    Super Grub2 Disk 2.04s2-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 features a new usb based image which lets you carry your loopback.cfg enabled distros in a second partition. Power users will be glad to learn that you can edit any Super Grub2 Disk file and make bigger the ISOs partition. Filenaming scheme for released files was improved. Finally Korean translation was added.

    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.).

    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.

    Changelog (since former 2.00s2 stable release)

    Changes since 2.04s1 version:

      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:

    • 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.

    If you want to translate into your language please check TRANSLATION file at source code to learn how to translate into your language.

    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.

    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.).

    Supported Operating Systems

    Excluding too custom kernels from university students Super Grub2 Disk can autodetect and boot most every Operating System. Some examples are written here so that Google bots can see it and also to make more confident the final user who searchs his own special (according to him) Operating System.

    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.

    • 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.

    If you want to translate into your language please check TRANSLATION file at source code to learn how to translate into your language.

    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.

    (Torrent)MD5SUM: ee5efcc09e4d9011d8bd865f354dae84

    Introduction

    This last week I have been unable to sleep. Why? My friend adrian15 told me about him releasing another beta version of Rescatux. The last Rescatux beta was released on December 2017. That’s more than a year ago.

    He has been hyping me about all those new features that this iso is going to have for the past two months. And he has also bothered me with all the problems he had been finding along the way. He is very persistent because he has finally managed to work around most of them.

    So, the first thing I want to point out is that Rescatux, as you might know is usually based on Debian stable. Well, Rescatux 0.51b3 was based on Debian Jessie 8 and Rescatux 0.71 beta is based on Debian Buster 10 which happens not to be a Debian stable because it has not been released yet.

    Debian Buster 10 will be release as stable Debian in the next months

    But Debian Buster is frozen and it will be released as Debian stable in less than a year.

    Using Debian Buster 10 instead of Debian Jessie 8 as a base means that more recent hardware will be supported out of the box. And that’s great because I recently bought a HP250 G6 2SX60EA laptop and I want to test Rescatux on it. So that I can give adrian15 more work Ha Ha Ha !

    The other nice about this iso is the many ways it can be booted. Super Grub2 Disk which has an hybrid boot that supports i386-pc, ia32-efi and amd64-efi boots is from the same author. So you should not an expect an amd64 only disk and an i386 only disk but an hybrid one.

    And that’s what you get. Here there is a boot options summary table:

    Secure BootBIOS/EFI platformKernel ArchBoot?

    Have you noticed it? Yeah, that’s it. Now Rescatux 0.71 beta 7 gets Secure Boot support from Debian Buster. And it’s Secure Boot which works with Microsoft Secure Boot enabled machines. So we are not going to need to tweak our UEFI firmware to be able to boot Rescatux. Yay!

    What more about boot? Yes, there is this liveid thing that adrian15 made up so that some hp laptops that come with live-build installations do not confuse Rescatux boot. That’s supposed to be a new standard for live cds but according to what he has told me not many distros are willing to adopt it.

    It’s UUID for live cds he has told me. It should be make easier the work of Yumi, Rufus, Easy2Boot and similar tools if combined with loopback.cfg according to him. Go figure.

    Hands on – Boot

    Enough talking. Let’s boot the iso and see what we get at.

    I’m getting an isolinux menu with a countdown when booted in BIOS mode. Look at that! The poor tux penguin has beta 7 all of over his face! XD XD XD . This needs to be fixed in the next stable release. #FreeTuxFromBeta7

    Rescatux BIOS boot menu #FreeTuxFromBeta7

    However when I boot in UEFI mode I am not getting a countdown and the default boot entry cannot be seen because it’s white and the background is also white. I remember seeing this same problem in Rescatux 0.51b3. This has not been definitively been fixed.

    Rescatux Desktop

    What about having a laptop with a semi broken screen? I had to install open-vm-tools-desktop package on my virtualbox instance but I finally managed to make it work with two screens. That way I can show it to you without using a blurry mobile phone photo 😉 . Guess what? Rescatux gets you covered because you can start the monitor settings when monitors are horizontally stretched. The dialogs concerning monitor settings are centered among the two monitors.

    So that means that I can finally recover my old broken screen laptop. I just disable my laptop screen and leave enabled the external screen. And there’s no need for me to learn hotkeys and commands to run those screen setup screens manually.

    By the way this monitor settings dialog is a part of the new Rescatux startup wizard.

    Rescapp was already a wizard for your rescue tasks but adrian15 managed to add this new wizard for the live cd itself. These new Rescatux startup wizard feature are quite neat so that you can customize your Rescatux session.

    • Change monitor settings
    • Change language/locale
    • Change keyboard layout
    • Turn off VNC Server or change its password

    VNC Server. That is an interesting feature for youtubers and maybe cloud users.

    Now Rescatux starts up a VNC server at startup so that you can access it from the network. I have asked adrian15 on how to setup an static ip from boot parametres as I had seen in the past in GRML but he has told me it is not implemented yet. ‘You have to rely on dhcp or setup the static ip manually.’ he has told me. Look at this, we are ready to run Rescapp. Finally! This was getting bored because Rescapp is what matters in this distro.

    Is this Rescapp?

    What do we have here? This is Rescapp. But this is not the Rescapp that I know of with all those options. Let’s read the windows title:

    Rescapp Self-Test

    Rescapp checks itself thanks to self-test new functionality

    I first thought this screen was meant for people to know if they had boot in Secure Boot or in UEFI mode. That’s useful because when playing with UEFI and BIOS boot I have learnt that every OS in the computer needs to be either boot in UEFI mode or in BIOS mode. Not the two of them mixed.

    Later on, while discussing with adrian15 about this option he has told me about him converting rescapp and chntpw (what makes possible to reset Microsoft Windows passwords) into proper Debian packages. As Rescapp is available as an upstream package or as a Debian package it might appear in other distros without being able to show its full potential.

    So now when a distro lacks SELinux support you know. If the distro has not packaged the forked version of chntpw that Rescapp uses then you also know. But you are not forbidden of using Rescapp. Maybe SeLinux support (needed by RHEL, Fedora, Centos,…) is not used by your usual distro so it does not affect you.

    So Self-test not only helps you to diagnose if you have boot in the proper mode (UEFI or BIOS) but also if your live cd is lacking some of the Rescapp requirements.

    After you click on the Start Rescapp !!! button you finally get out beloved Rescapp.

    Our beloved Rescapp UI

    Rescapp not so updated and angry call

    I took a depth look into Rescapp for about long thirty minutes but I didn’t see anything relevant. This was confusing. I was expecting some Secure Boot options now that Rescatux could boot from Secure Boot machines. I was expecting him to fullfill all of the options embeded html documentation that I had complained to him when he released 0.51b3 version and I had to dig inside his rescapp scripts to understand them.

    I had to phone adrian15.

    He laughed at me. He was expecting my call. Too much work on putting up Rescatux up to date and adding all of those fancy wizards was his explanation. When I was going to complain to him about the awful design of the beta7 text in front of the now sad penguin he told me: Pull requests are welcome and he hung up the phone on me!
