What was the disk device name?  Your WinXP disk was probably /dev/hda. 
What was your new drive called?

Now you are changing the device name of your new hard drive.  You have 
probably changed it from whatever it was to /dev/hdb.  You will need to 
change all of your Linux references to your HDD in your grub.conf file 
to reflect this change.

Yes, grub can no lionger find your "old" controller with the HDD on it. 
 You need to tell grub where your new drive is again.  The good news is 
that after you edit your grub.conf file, everything should work again. 
No need to reinstall grub or anything else (assuming that grub was 
installed in the MBR of your first hdd.

Ow, ouch!  Now you really screwed things up!  (not really!)
Go and get your rescue CD, boot from it, and use its utilities to 
re-install grub (this time with the correct disk references for your 
Linux boot and root info) into the MBR.  Running FDISK restored the 
WinXP boot stuff.
