Product Key not accepted for reinstall

January 19, 2011 at 17:33:50
Specs: Windows XP
I have a laptop which was purchased through my daughter's company. It had been working fine until I downloaded windows updates (which I have done many times), I did and was asked to reboot. When rebooting I received a login error message (sorry I didn't write it down) then received the BSOD and the computer kept rebooting. I borrowed a XP Pro disk (which the computer has XP Pro) since I didn't have one to re-install, all was going fine until I got to the product key - I entered the key which is on the COA and got a message that it is not valid. Please help. I also have another computer which has XP Pro (computer not working anymore) so that license would also be valid/available since it is no longer in use. How do I get past the product key screen.

Is this an actual windows xp pro disk? It could be you have a version of xp pro that uses a volume license. Or you have a standard xp pro disk, and the windows key is for a volume license. XP pro uses different keys to detect a volume license or single license purchase. The fact this came from a company leads me to believe that is why the key does not match the version of xp pro you are installing. Does the coa say for xp pro or home?

The disk is a copy of the XP Pro disk. I do have the license number for the computer that is installed on but did not try it since that license is in use. The COA is for XP Pro

You need to find out what type or version of Windows XP PRO your COA on the laptop is: It could be and OEM version, it could be a Retail Full Version, it could be a Upgrade version or like #1 response it could be a Volumn License Version.
Keep in mind that each one of there require you to use the matching CD for the Version you have on your Laptop, before the Product Key will work.
