However as my currently installation is the OEM version of Windows (came with my laptop) and the disc will be the retail version, will my product key activate the installation? I don't want to wipe my computer to load a 30-day trial of Windows. I have no recovery partition and no recovery discs (Identically made a Windows repair disc instead of a TOSHIBA recovery disc) and therefore the only way I can re-install Windows (Without buying TOHSIBA recovery discs) is to borrow an installation disc from a friend and use the product key ont eh sticker on the bottom of my laptop. I need to wipe my laptop due to issues on my computer (BSODs etc.).
