   Warning

This will not work to install Windows 8 or 8.1 for UEFI. For that, see this tutorial below instead.

_____________________________________

With Windows 8/8.1 The Product Key on preinstalled Operating Systems (HP, Acer, etc) is embedded in the BIOS in the Motherboard, so that the lost and/or worn C.O.A. Sticker problem is no more.

When you reinstall it will pick up the Product Key and activate the system automatically.

If it does not, follow these steps:

Many thanks for the response. I would also like to know why the product key on the disk, 'manufacturer's factory installed product key" is wrong when I enter it in the product key section. What is the difference between this key and the "correct key" which the computer is asking for?
