If you are doing a fresh windows install onto an SSD on a motherbaord which supports uefi, should I format to gpt and install through uefi or just stick with mbr and install the 'old' way. Reason I ask is that I've setup up a pc for my brother and recently it's had nothing but problems with it failing to boot. I managed to do a windows system repair but a week later it failed to even get that far. I have installed windows and some programs to a new SSD formatted as gpt with uefi but a week later and it won't boot again. Other thing i haven't tried is a bios update as its the sort of thing i'd rather not do on someone else computer. The motherboard is an ASUS maximus p67.
