I have both OEM copies I have one from dell and I made one through alienware respawn and both of them are usbs. How would I go through with the swap?
Hmmm. Not sure about that one you made via Alienware and whatever that "respawn" program is. Sounds to me like that's more of a restore for that Alienware laptop than an entire OEM copy you can slap on a different HDD into another laptop.
You might want to check from Dell's support if both are actual fully licensed OEM copies to reload from a completely wiped out hard drive. Just tell them you are wiping out the HDD for each and want to reload everything from scratch.
If they are full OEM copies, then all you do is wipe out each HDD entirely with a full reformat and swap them. Then load the OEM OS for each laptop that was originally assigned, download and install all the drivers for each laptop from Dell's support page, and then restore your file folders from whatever external sources you backed them up to. (It's not a short process on one computer, let alone two).
