k, thanks for that reply. I noticed when I built the rescue there is a grayed out checkbox that says something like,Enable multiboot MBR/UEFI BIOS bootingWhy is that grayed out regardless of PE version? I built rescue ISOs for PE 3.1, PE 5 and PE 10, it it was always grayed out. The only one I didn't build is for PE 4
It might depend on the target you select. Discs and ISO files include support for both types automatically, so if you select those it will be grayed out and checked, forcing it on. If it's grayed out and UNchecked AND you're choosing a USB device as the target, I'm not sure.
