I bought an Asuz Zenbbok UX31A with windows 8 a while ago. After I bought it I decided to put windows 7 on it and everything worked fine. Yesterday I updated my bios in order to fix a fan issue and it was flashed successfully (as far as I know).
After restarting the computer it now goes straight to BIOS, it doesn't find any partitions that it can boot to.
I believe the issue is because the "Launch CSM" option is disabled, but I cannot enable it, it is greyed out. Does anybody know how I can get it to let me change the setting? (Or is there something else I could do?)
