When the bootloader (probably lilo or grub if x86 arch) prompt appears,
simply add the kernel parameter root=/dev/<desired root partition>.

However, this will still load the kernel from the drive that was moved
and it could be incompatible with the original root filesystem
(/lib/modules in particular).  The grub command line can fix this by
loading the kernel from the original boot partition.

Booting from a live CD should always work fine, especially for disk
recovery.

These are excellent (and very terse) suggestions by Daniel.  (I would
use ATA rather than the generic acronym IDE, though.)  The unqualified
use of the acronym BIOS of course refers to the motherboard BIOS.
