    Did you boot the Windows 8/8.1 in UEFI mode?

    W.8.1 Pro Update 1


    I thought I booted the W8 install disk in UEFI mode. Now that I got a running W8.1 system using the Legacy BIOS mode on a system with a BIOS that supports UEFI mode what functionality have I lost? Everything seems to work and appears more straight forward in Legacy BIOS mode.

    Compared with MBR disk, a GPT disk can support larger than 2 TB volumes where MBR cannot.

    Just a follow up on my UEFI saga. It was my ignorance that was causing the problem. I needed to "Hit any key" to boot the W8 setup disk in UEFI mode - don't need to do that in "MBR mode". I must have done the "Hit any key routine" and got it right the first time I installed W8 many months ago!

    The reason I went back to square one and figured out what I was doing wrong was the MBR installation started giving me the Explorer.exe Error 1000 where the W8 desktop paints correctly at boot up and then goes Blue Screen for several seconds and then repaints. This is the second time I have run into this problem on two different W8.1 machines! In both cases, a fresh reinstall makes the problem go away?! I started a separate thread on that issue several days ago but it pretty much went unresolved a far as the root cause.


    Anyway, thanks for all the help and information on the UEFI stuff. I think I'm a little smarter now.
