Is there any easy way to install Windows 7 x64 with GPT and UEFI? If not then I have to change to MBR and install in Legacy (BIOS) mode. Thanks .
The docs.msft page is literally an s-b-s guide on how to integrate drivers. You just have to replace the relevant parts of it with your environment variables.
I tried adding USB 3.0 drivers to the boot.wim and install.wim with PowerISO, I got them from the AMD Chipset drivers, and it didn't work. Still have no idea, have to install via USB 2.0.
