I misunderstood you.  I thought you wanted to move your data from one
disk to the other and then make the partition you just copied the data
to your new root partition rather than change where your drive is
attached.

Like the others said, you want to boot into single-user mode to change
the fstab.  Also, in order to get it to boot using LILO, look at the
bios=<param> option in lilo.conf(5).  (More discussion on that is
available at <http://www.linuxdoc.org/HOWTO/mini/LILO-4.html>.)

Or you can make a boot disk to get you past the first boot.  You'll
probably want a bootloader so that you can boot into single-user mode to
change the fstab.  If you don't have one (either one that you've made or
from your distribution), go get
<ftp://alpha.gnu.org/gnu/grub/grub-0.91-i386-pc.ext2fs> and dd it to
floppy.

Not any more than in MS Windows.  (fdisk, reboot, format, run xcopy32
with some options I currently forget, shut down, switch cables...)
