Hi,

See if this assists you with your Repair options.

You can use the power button to restart your computer three times. This will start the Windows Recovery Environment.

_____________________________________

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:
