'OEM keys work just fine'
"...The product key you entered appears to be for software pre-installed by the device manufacturer. Please contact the device manufacturer for software recovery options..."
No luck there! There's far more users with bundled OEM copies than separately purchased. Anyway, guess I'll just have to image the drive. Its been a while since I did that kind of thing. Is there anything built-into Linux to help... If I install Mint on a separate partition is there a tool that will image the NTFS partition etc?
