Regards Sid. Shouldn't be necessary because you switch the disks, but, did you check device.map ?
Regards. ---------------------------------------------------------------------
I certainly did and it is the same before and after the problem was fixed. I also had removed the line "(hd1) /dev/sdb)". (fd0) /dev/fd0 (hd0) /dev/sda I'm perplexed as to why simply removing the IDE drive would cause the SATA drive to suddenly not boot, must have been something in the stages.
Coming to this party a little late, but the reason why the SATA drive wouldn't boot is because by removing the IDE drive, you changed the device name for the SATA drive. It went from hd1/sdb to hd0/sda, and so everywhere GRUB was looking for hd1 or sdb had to be changed to match the new disk layout.
I wrote up a short bit about restoring grub here, after they messed with the easy page found on the ubuntu wiki:
http://linuxbraindump.org/2007/08/17/restoring-grub
Of course, this just allows you to boot grub. You will also have to edit the menu.lst file for it to find the new locations.
I found what I wanted on the Ubuntu wiki when pointed in that direction, then I asked myself why I didn't google for an answer - probably at 04:00 you are never as smart as after you've been to bed.
