It sounds like GRUB made the MBR on /dev/sdb to use /dev/sda1 as its |
| 19 |
root, so maybe something like |
| 20 |
|
| 21 |
# grub --no-floppy |
| 22 |
grub> find /boot/grub/stage1 |
| 23 |
(hd0,0) |
| 24 |
(hd1,0) |
| 25 |
|
| 26 |
Then making GRUB install on /dev/sda pointing to /dev/sda1 |
| 27 |
|
| 28 |
grub> device (hd0) /dev/sda |
| 29 |
grub> root (hd0,0) |
| 30 |
grub> setup (hd0) |
| 31 |
|
| 32 |
|
| 33 |
and now install on /dev/sdb pointing to /dev/sdb1 |
| 34 |
|
| 35 |
grub> device (hd0) /dev/sdb |
| 36 |
grub> root (hd0,0) |
| 37 |
grub> setup (hd0) |
| 38 |
|
| 39 |
Then you can quit GRUB by issuing |
| 40 |
|
| 41 |
grub> quit |
| 42 |
|
| 43 |
The point being that once you put in the line "device (hd0) /dev/sdb", |
| 44 |
GRUB will *think* that (hd0) refers to the disk /dev/sdb, so the next |
| 45 |
command "root (hd0,0)" just means the first partition on this disk |
| 46 |
will serve as /boot, rather than (hd1,0) which points to 1st partition |
| 47 |
on the *other* disk, which is possibly where GRUB got confused. |
