Ok, on one system I had /boot as /dev/md0, and md0 is composed of
/dev/hda1 and /dev/hdb1.
I have done:
grub> device (hd0) /dev/hdb
grub> root (hd0,0)
Filesystem type is ext2fs, partition type 0xfd
grub> setup (hd0)
Checking if "/boot/grub/stage1" exists... no
Checking if "/grub/stage1" exists... yes
Checking if "/grub/stage2" exists... yes
Checking if "/grub/e2fs_stage1_5" exists... yes
Running "embed /grub/e2fs_stage1_5 (hd0)"... 16 sectors are embedded.
Running "install /grub/stage1 (hd0) (hd0)1+16 p (hd0,0)/grub/stage2
Am I in the right way?
