Dont think it will work mate as i siad its set up on the hard drive of the pc for one recovery disk only that come with that pc.
Look at it this way mate if you could do what you say and put a disk in of some other pc thats thats same make then if you had a nicked pc you could then just use your recovery disk to put it back to factory settings, CAN NOT BE DUNE one disk one pc.
The easyest way is as i siad mate just format the hard drive and put windows back on with all the software your mate would need to have on it.
This way he wouldent need a recovery disk only a copy of windows.
? What windows OS is on the pc now.
You can not put a recovery disk for what you think is the same pc in his it will not work and you may have to go into doss and change a lot of setting in there to get the disk to work, the only way to do that is by way of phoning custermer serveces for the emachine and thay will tell you how to do it at 1 pound a minet or what ever it is NOT GOOD.
