Bug#550702: Similar problem with HP/Compaq nx7300

[wzabolot@elektron.elka.pw.edu.pl]

I had similar problem with HP/Compaq nx7300. Booting linux (even
different versions of kernel) didn't cause any trouble.
Booting Windows XP Home (installed automatically by os-prober) caused
grub to hang immediately after displaying "Welcome to GRUB!"

Maybe either grub-ps, or os-prober should detect such dual-booting
situation and automatically propose the workaround with:
# install-mbr /dev/sda
# grub-install --force /dev/sdaX
?
