how could i change my drive from AHCI to Compatibility Mode! Because I read that doing so mite boot the OS from the HDD.
I also read you do it by pressing F2 ---> BIOS --> Advance --> and select AHCI to Compatibility!

But wen i press F2, i cant see BIOS screen or anything, I tried everything, f2, f9, f10 but cudnt find BIOS menu!
So my question is from where could i change that, because it mite work after this
Thanks
