A boot loader.
This is one of the "big" boot loaders. I can't fathom it (since it's GNU), so I expect a distribution to be magic with it.
When GRUB breaks, I use boot-repair.
- (date not recorded) GRUB 2 - (version not recorded), on (distribution not recorded)
(date not recorded) GRUB 2 - (version not recorded) ∞
This was likely tested around the same time as 2011-08-22 - GRUB 1 - 0.97, and with the same distribution/version.
2011-08-22 - GRUB 1 - 0.97 ∞
Tested 0.97 on 2011-08-22 Unity Linux, updated 2011-07
