Super Grub Disk and Super Grub2 Disk Difference

GRUB2 is a complete rewrite of GRUB, and Super GRUB2 Disk is a complete rewrite as well. As Super GRUB2 Disk uses GRUB2, the differences between GRUB Legacy and GRUB2 also apply to the different versions of Super GRUB Disk.

Perhaps the most notable difference between Super GRUB Disk based on grub legacy and Super GRUB2 Disk is that Super GRUB2 Disk does not write to the disk at all, and so cannot rewrite the MBR. Super GRUB2 Disk can only be used to boot a broken system, it cannot fix it directly. Though once a system is booted, re-installing grub is usually just a matter of running “grub-install /dev/sda”.

While there are some features of Super GRUB Disk based on GRUB legacy that will never be included in Super GRUB2 Disk, the opposite is also true. For instance, Super GRUB2 Disk supports booting OSX, loop booting from iso files, booting an OS from USB without USB support in the BIOS, and other features that are not possible with GRUB legacy.

  1. First and foremost, your solution saved me fron wasting days and the accompanying misery of a rebuild.

    Like most others and desperate for solutions, I worsened the problems by resorting to unathorative blog posts for solutions most of which nonapplicable and broke things further.

    Forced to convert the boot repair into a data retrieval /salvage operation –the last tr was your ISO since accumulated anger resulted in literal fistpounding permanently cracking the keyboard into generating “n” instead of “M”.

    Two modified “N” keys and a 500MB download and Linux is booting just asif I didn’t break it along with hard bitten lessons learned.

    I’ve been shouting loudly about your tools Magical benefits and nicknaned it Grub’s2ndChance. Youve likely saved more systems than you could every know…but if you quantified all the systens rescued from Map corners to edges….you have More free Meals and hospitality awaiting you for many lifetimes.

    1. I was about to chide you (good naturedly of course) about childishly breaking your keyboard. But then, My wife reminded me of my last UEFI battle with the dog cowering behind the couch, and the parrot learning several new words she shouldn’t have, and decided I had better leave it alone! 🙂

      however, just cried out for confirmation. You said it best, I can only concur.
