if you want to boot from /dev/sdb, why do you tell grub |
| 20 |
to use (hd0,0), which usually maps to /dev/sda1? |
| 21 |
|
| 22 |
I'd expect to see root (hd1,0) in there somewhere. |

Depending on boot flags and BIOS settings, you might still |
| 25 |
be using the MBR on /dev/sda. |
| 26 |
|
| 27 |
When I migrated a client's data over to a new disk a while |
| 28 |
ago, I basically used "tar cf - /sda | tar xf - -C /sdb" and |
| 29 |
then switched SATA cables before rebooting. The former /dev/sdb |
| 30 |
became /dev/sda and everything was fine. |
