Yes exactly my windows is OEMIf you get that message, it means you have a system builder/oem license so you will need to get install media from the computer manufacturer.
thanks for your replyYou'll just need to look at the manufacturer site. They may have the option to download the media or you can pay for physical media I've seen them range from $10-50
thank for all these information,Actually, it's now between $29-$99 US for factory Recovery Media.I order them for all the major computer makers for use in rebuilding broken customer computers from Dell, Acer, ASUS, HP, Lenovo, and Toshiba. This cost may be more outside the US; we have users here who tell us they have paid up to $300 US for Recovery Media outside the US, due to import restrictions and taxes.
FYI.
