I'be been trying to install Windows 8.1 using bootcamp on an Early 2011 Macbook pro. I've been using a bootable USB thumbdrive made with Unetbootin.
I edited info.plist to enable loading the win 8 iso from USB. I'm not sure if this is relevant.
Windows keeps giving the error "Windows cannot update the computers boot configuration, installation can not proceed" when running the windows setup.
I had a problem with a hybrid MBR disk, and fixed it as explained here. Windows detects GPT disk as MBR in EFI boot
Here is the output of gdisk; is there anything obviously wrong?
