Pity you can not specify 2 boot images... regular and UEFI files. IE old disk Boot image , was done with Sysprep. however some of the wims are patched , however patching and shimming UEFI , a plus. so far copy /b boot.ima + efisboot.com test-boot.ima... ? since its for the cloud anyhow , trying to find a way to slipstream in UEFI into current loader , test before burning to an actual release Image.
