I still find it amazing that people still try this on.
The OEM disc you have would have been intended for, and supplied with, a full computer system. It was for use ONLY on that system, and cannot be installed on any other. If that original computer no longer exists, the disc must be destroyed.
ve just seen the earlier post. If I have read that correctly, you already have an illegal installation (Dell CD on a Packard Bell PC) I don't think you'll get much more help here. Go out and buy a legal retail copy of XP, then we will help you.
