I just updated from 11.10 to 12.04, with no major problems (it took a while to get past a request to restart ssh, mysql and some other services, but I did no fiddling by myself, everything was done by the installer). However, after restarting, grub can't do anything. Picking the new linux installation (first entry), I just get
error: no such partition
error: no such partition
error: no such partition
and picking the recovery-version just gives 5 lines instead of 3.
I have windows 7 installed on a different drive, and can run it by booting from that drive instead. Picking it from the grub menu gives the same error as above (can't remember how many lines, though). I'll be honest and say that I don't remember if win 7 could be booted from grub before the update, though.
In short, nothing on the grub menu works.
any solutions? The grub menu changed appearance - before it was on a purple background, small letters, now it's white-on-black, big letters, looking very basic.
The original installation was from a usb-drive, and I hadn't heard about wubi until I started googling this problem, so I doubt there's any connection.
I really hope there are some grub-savvy people out there :)
EDIT:
ok. so, I made a bootable usb, and am running from that right now. when I ran the bootinfoscript, it warned me that
"gawk" could not be found, using "busybox awk" instead.
This may lead to unreliable results.
just so you know.
