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 ? -- TIA, BR, Wojtek -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
