FYI ... an OEM branded Recovery Disc is not the same thing as an OEM branded OS Disc & as hinted above, not applicable for reloading any typical IBM-compatible machine. In most cases, it is not compatible across machines from competing OEMs.
OEM branded OS Discs, on the other hand, can be used in the same way as you would deploy any retail OS disc from M$. And insofar as you possess an authentic & legally obtained license to the OS you're installing, how or where you got the install media from is irrelevant.
