I currently have Windows 8 32-bit installed from MSDN (I didn't realise at the time that my processor supports 64-bit).
I understand that you can't upgrade within Windows 32-bit to 64-bit directly from the ISO.
I have burned the ISO to a DVD, and have attempted booting from this drive.
The problem I am encountering:
The operating system couldn't be loaded because a required file is missing or contains errors.
Error code: 0xc0000221
You'll need to use the recovery tools on your installation media. If you don't have any installation media (like a disc or USB device), contact your system administrator or PC manufacturer.
