My Notebook came with Win8 pre-installed. Without waiting to do a backup, I immediately updated it to 8.1. That altered the location of the recovery partition, so I can't now reset the system. Asus want me to send it back to restore the original system, but I would like to buy a new full version and install it myself. Will there be any issues with keys? Or will the new disk be able to overwrite the existing key in the BIOS. Help would be appreciated.
