I repaired a computer that had XP installed using my XP disk; I didn't have the disk used for the original installation. I thought I would be able to use the product key taped to the side of the system unit, but it doesn't work. I was using Recovery for something minor and would like to get back into Windows, but each time the computer starts it wants to continue the setup. Since this is not my computer, I didn't want to use my key on it. I read that maybe something can be done with boot.ini but I'm not sure if it applies here. Thanks for any help.

The Key only works for 3-5 times depending on license. You can still use it you just have to call Microsoft to reactivate the key. During the Setup choose Telephone Registration. Then call the number it provides you and give the automated lady the code on your screen and she will give you the corresponding numbers back. I know its a pain being that they use voice recognition and some times you have to repeat the numbers but it works.

I thought the problems with the key limit was when you tried to activate windows during or after the 30-day activation period. Right now I can't get into Windows because the repair/setup wants to continue.

Using bootcfg /list, there are 2 entries in the boot list: 1. Microsoft Windows XP Home Edition. OS Load Options: /fastdetect OS Location: C:\Windows 2. Same as the other listing above but has this under Load Options: /noexecute=optin /fastdetect
