Grub hanging

[Tony Baechler]

You didn't give background information leading up to the behavior you 
describe, so this is only a random guess.  It sounds like the GRUB image is 
out of sync with the image installed in the MBR.  I would boot a rescue CD, 
chroot into the Linux system, make sure all updates are installed paying 
especial attention to GRUB and run grub-install on your boot drive.  If that 
doesn't work, I'm afraid I don't know.
