I've been trying to install Windows 8 on a UEFI-based computer using a USB flash drive. As far as I've have been able to gather, there have been some issues with this kind of installation, as the DVD images fail to boot in UEFI mode. Following this tutorial http://blog.thijssen.ch/2012/07/install-windows-8-in-uefi-mode.html, I've able to install from 64-bit only iso's, however I'd like to install from a AIO iso (only one available in my native language).
I've tried copying the bootx64.efi files from the /efi folder of a 64-bit image, but I get an error screen. Is there a way to fix/correct the iso image so that it can boot in UEFI mode?
