    Windows 8.1 clean installation; won't boot in UEFI?

    Hi guys,

    I recently bought a new SSHD for my laptop and after initial problems with trying to install Windows in UEFI, I turned to Legacy and that worked. But now when I change it to UEFI, it just comes up as "Operating system not found".

    Any ideas or solutions would be greatly appreciated, thanks.

    You may have to reinstall so you will have the UEFI configuration. But what about the original install gave you problems with UEFI, were you able to boot into the UEFI version of the install media?
