Hello, I am getting the same message as many and have reviewed many articles including, "How to recover from a corrupted registry that prevents Windows XP from starting." I cannot use that article because the system was OEM installed and they did not provide the CD that is recommended for use in just this situation. My husband attempted all of the options once hitting the F8 as well as using System Restore. The computer cannot get past the start up so safe mode and system restore do not work. Two questions: 1) How can we fix without using the recommended CDs? I am not sure this is even possible. 2) If it isn't possible, what is the cheapest/quickest way to get the CDs? Thanks so much!
