I have dual boot (linux/windows) and everything was working well.
Suddenly a couple of days ago, I couldn't get in to Linux (Gutsy Gibon).
Grub comes up, the menu (including the correct disk notation) comes up.
If I press windows, it goes to windows. If I press on the Linux line, I
get a message "cannot mount selected partintio: press any key to
conyinue". and the I get back into Grub. Any ideas.
