GRUB#

GRUB is not installed#

Error:

GRUB Loading stage1.5.

GRUB loading, please wait...
Error 17

Solution#

Recovery-CD -> Root Shell:

fdisk -l

to list all partitions. Remember /boot/-Partition (e.g. /dev/sdb1) and its GRUB-equivalent ((hd1,0) in this case). Then:

grub

to start GRUB’s shell and feed it with:

root (hd1,0)
setup (hd1)
quit

and reboot.

If Grub does not work after rebooting, simply press e in GRUB’s boot menu to go to the edit mode of the boot entry. Press e again to change the line root (hdX,Y) to e.g. root (hd1,0). Press b to boot with the new root partition.

Explanation#

The right partition#

… is wherever your /boot is. This command tells you:

df /boot

The kernel’s root argument#

… expects a path to the inititial ramdisk. If you have a seperate boot partition (which you should), then root=/<your-initramfs-file-name> is correct. /boot could also be a simple directory under /. Then the kernel argument would be root=/boot/<your-initramfs-file-name>
