UnEducated and F'in Ignorant? (UEFI) because I don't understand wtf is going on with this Asus 77 board. Normally, I boot my USB stick containing the Win7 installer and select a drive and wa-la. On this board, Windows installer doesn't detect the hdd. Typically I'd think it needs a SATA driver that 7 doesn't have so I switched the SATA mode from AHCI to IDE and the same thing happens. Can someone explain UEFI and it's purpose? Is that what's causing this?
