I assume you reconfigured GRUB with 'root (hd0,4)' 'setup (hd0)'?

This is wrong. The partition type should be Linux. Run fdisk and change
the partition type.

Are you sure the number of blocks is still the same as it was before
moving?

First change the partition type to Linux. Does e2fsck run properly now?
Then edit /boot/grub/menu.lst to your new settings, something like:
title Debian GNU/Linux, kernel 2.6.10
root (hd0,4) <--- this is your extended partition
kernel /boot/vmlinuz-2.6.10 root=/dev/hda5 ro <--- idem.
savedefault
Also check your XP record (I don't run windoze, so I can't help you with
that one).
Then run grub and type:
root (hd0,4)
setup (hd0)
and see if you are able to boot again.
