First thing is to find that recovery partition and learn how to start the recovery process. If you ever format the drive, that option will be forever lost!I don't know what your OEM is, but I've been making nLite'd disks for DELL's using my copied DELL OEM XPPro disk for over a yr now. I haven't had any problems doing it this way as yet. This method also works for, Compaq, HP and eMachine. You just need to copy the OEM disk to a folder and save it for later use. Also I'm doing XP Home the same way. I started doing this, with my DELL which is XPPro SP1a, by restoring my OS from the factory image partition(DELL calls this PC Restore) and install the nLite'd XPPro, on top of the restored OS. Using RVM's update packs, I usually have anywhere from 0 to maybe 5 updates to install. The whole process from start to finish, that's replacing the "OS", drivers, "My Documents", Theme's, and all my programs: ~3hrs! I hope this is of some help to you.
