Windows 8 OEM Reinstalling

It will install, but the problem is it will reject the key. An OEM key requires an OEM disk, and retail requires a retail disk.

You did not post what model or brand of laptop, so it is hard to be more specific with the following advice: First, I would call the manufacturer and see if I could buy a replacement disk (about $20 typically because you are not buying a license, just the media). That is a good idea long-term.

In the short term, you want to get up and running, so see if you have a friend with an OEM disk even if it is not from your manufacturer. I have used the Dell restore disks on non-Dell systems before. The main difference is that if I were installing it on a Dell system, it won't ask me for the key or to activate, but it does on a non-Dell system. This is not a problem for you since you can just put in you key that is on the sticker.

You will need the standardized OEM install CD. It will work with all OEM keys. It does required a phone call to activate the install however. The CD has the normal holograms but also has the text "For distribution with a new PC only. The Certificate of Authenticity label should be attached to your PC. For product support, contact the manufacturer of your PC." on it.

I don't think it's available from MSDN so you have to ask friends or others at work if they have such a CD. Checking for the text makes it easy to tell a retail Windows XP disc from the standardized OEM one.
