Hello Joe,
This is a desktop, it came with just free DOS on it however ive tried to install windows 7 on it via USB and Disc, however it just blue screens, however when I use a bootable version of Windows 8 it installs fine. Finally in the BIOS i have tried secure boot on and off, also legacy devices are allowed and ive tried turning CSM on and off but still no luck.
Thanks for your help.
Cheers
