How to delete a second WINDOWS on the backup partision D: drive?

[oldham]

Inspiron E1505 would not boot. Loaded WINDOWS onto the backup partision D:drive and was able to work on the C: drive till I got it to boot again.

Now I need to delete the second WINDOWS on the D: drive to get everything back to normal. HELP?

NOTE, I just want to delete the windows XP out of it, not he drive/partition itself. The backup partition was the to begin with. I just want it back like it was. Thanks
