I have recently purchased a new Lenovo C540 that has Windows 8 already installed on it (please note I have posted in Lenovo forums, awaiting solution there as well). I would like to perform a clean install of Windows 8.1 on this computer.
This is what I have done so far:
1. I disabled 3 things in the BIOS: IIRC, they were secure boot, quick boot, and something about "optimized"...
