Partition table entries are not in disk order
sid:/#
/dev/hdb1 corrisponde a debian
/dev/sda1 corrisponde a suse
entrambi sono in reiserfs

questo il menu.lst di suse

Il problema è che al boot il pc mi salta grub (me lo visualizza meno di un secondo) ed avvia automaticamente debian impedendomi la scelda del s.o., che posso fare?

Ho già tentato di prendere suse col chroot e ridare il grub-install ma mi da il seguente errore:

codice:
sid:/boot/grub# grub-install /dev/hda
/dev/hda: Not found or not a block device.
sid:/boot/grub#
