Hello modders, I'm having a hard time with WinPE 4.0. For starters, my USB is 128GB, which means I have to use exFAT - according to some people, it should work, but others say it won't. So far no luck. Also, it's my only USB and I really would appreciate a foolproof way to boot both x86 and x64 WinPE 4.0 from it. Even if I have to use separate partitions, that would be fine. Finally, I have to do this in UEFI mode.... BIOS won't work on the device I'm trying to boot to. Is this even possible?
