Normally its best to take the least number of steps however unfortunately some of the newer systems require former BIOS updates to be installed first. When you launch the BIOS update it will tell you whether its supported or whether you need another version first. If it freezes just leave it to complete as its likely doing something in the background. You are reading through some older information, many preferred to update via a floppy disk in BIOS in the past which I would say is more risky. The BIOS updates are a bit better these days and its harder to install the BIOS update outwith Windows for most systems. If you have the clean install you should be fine.
I've read i need to update my X51 R1's A03 bios to A14 to use my EVGA 750 GTX. I'm afraid of bricking my motherboard.  What causes BIOS update failures? People have stated about the windows version freezing and stuff. Can anyone explain the me?  Thank you.
