A repair install will fix the OS without losing your data, assuming you
have a proper installation CD, and not just a recovery CD. Google for
'Windows XP repair install' for details of how to.

Hmm, it's kinda muddled but are you saying you made the old hard drive with
Win2K on it the primary and booted from it with the WinXP hard drive as a
secondary hard drive? If this is the case, the partitions on your XP drive
have been renamed in the MBR of the XP drive to follow those of the primary
drive; when you make it a primary drive again and try to boot from it now
the renamed drive letter sticks, e.g. at D: or some other letter depending
on the partition structure of the old hard drive, and it doesn't know where
the OS is.

One M$ recommended procedure to reset the drive letters of your XP drive --
basically wipes the mangled drive letter assignments in the MBR -- and the
simplest one, is to make a Win98 bootable floppy with FDISK on it. Boot
from that floppy and enter FDISK /MBR.

When you added the second disk, you changed the disk and/or partition
order. Now your boot.ini file is pointing to the wrong disk and/or
partition and doesn't find the operating system. Use a bootable floppy
with an editor and correct the boot.ini entry so that it points to the
partition containing the OS. If you don't know what your disk and
partition entries are, or the boot.ini syntax, then you need to
research this and figure it out. You may still have issues if the
partition letter assignments have changed, but at least the OS will
boot.

Alternatively, you can simply do another installation of Win XP on
some partition without re-formatting the hard disk. Your data files
should remain intact after doing this, as long as you don't format
anything.

Try 'testdisk' utility and use it's file system analyzation
capabilities to rebuild your partition table.

Like someone else suggested, try booting from the WinXP CD and run the
repair procedure - sorry I don't recall details.
