'ls ((hd0,msdos1)/grub' to continue checking. Also, the command 'set' should have a value for 'prefix' which points to a sensible location for /boot/grub. > grub rescue> ls (hd0,msdos1)/ > config-3.2.0-4-amd64 grub initrd.img-3.2.0-4-amd64 lost+found > System.map-3.2.0-4-amd64 vmlinuz-3.2.0-4-amd64 > > What's not clear to me is how it helps me. Perhaps I could try to boot > the system from grub rescue (see below)? This was the direction we were heading in. But note that initrd.img and vmlinuz are not on (hd0,msdos1) and that 'root=...' is an instruction to the kernel telling it where to look for /sbin/init. GRUB understands (hd0,msdos2); the kernel does not. > grub> linux (hd0,msdos1)/vmlinuz root=(hd0,msdos2) > grub> initrd (hd0,msdos1)/initrd.img > grub> boot > > Perhaps the system will boot this way. Then what? There's still the > question of making the new HD bootable the normal way that remains. Not only is there no TAB completion and command history but you have to handle module loading yourself. 'insmod normal' and 'insmod linux' are needed. Then, if (hd0,msdos2) holds /sbin/init, follow up with grub> linux (hd0,msdos1)/vmlinuz-3.2.0-4-amd64 root=/dev/sda2 grub> initrd (hd0,msdos1)/initrd.img-3.2.0-4-amd64 grub> boot 'grub-install' and 'update=grub' after booting would be first steps on the road to recovery. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
