I cannot boot into GRUB. I see this:
Alloc magic is broken at XXXXXX Press any key
but when I do nothing happens. Holding shift doesn't do anything either.
The last time I could use my machine I changed stuff in
/etc/grub.d, but I chrooted into the system, reverted everything and successfully ran
What can I try?
If anyone wondering: Ubuntu 12.04.1, Installation media was (I guess) 11.10, it's an i5-first generation kernel, 4GB RAM, memtest was okay.
