When I installed Win 8.1 on my computer, I chose MBR install because I didn't know what GPT was. I have since learned that a GPT partition structure is necessary for Secure Boot and, for all I know, other things too.
I am contemplating re-installing win 8.1 with UEFI / GPT, which I realize means formatting the drive, and then restoring the programs I will have backed up. I am in no real hurry to do this, and I might wait until Windows 10 is released (the official version, not a preview version).
So I have the following questions for anyone knowledgeable:
Are there any features, other than secure boot, that need GPT?
I am thinking that for back-up, and restoring, I should just make a backup of my registry and move the directories I want to save off of my boot drive before re-installing.
After re-installing windows I could move the relevant folders back to the boot drive, merge my registry backup and everything should work again, right?
