The problem is, when booting to that ISO from Ventoy with the autounattend.xml file, it will only load a black screen with a solid console cursor for a few seconds and then return to the Ventoy menu. This tells me that it does not recognize that ISO as bootable. I have not made changes to the ISO aside from adding the autounattend.xml file to the root. I'm unsure if this is because it's Windows 11, or if it is perhaps a problem elsewhere. I've seen online that supposedly, you can use autounattend with just the ISO (as in, not by using software like Rufus to mount the ISO to a USB and placing the file in the root of the USB). In WSIM, there are no validation errors, at least... Anyways, here is my autounattend file. I've changed the user information and product key for obvious reasons. Any help is greatly appreciated.
