UEFI multibooting - new YouTube video
If you need to UEFI-boot and your target systems do not have an MBR\Legacy boot option, you can add WinPE boot files to a second FAT32 partition on your E2B USB drive.
EBook #3 contains download links for pre-made WinPE files which are compact, fast-loading and will automatically run SWITCH_PE.exe when they boot. This means you can quickly select any .imgPTN file you need on UEFI-only systems.
