When you UEFI-boot from a FAT32 .imgPTN file (after you have 'switched' it in), then there is no front-end boot manager. Whatever payload you have used is directly booted to. In this way E2B can secure-UEFI-boot to many different types of payloads without any issues or complications caused by other bootloaders/bootmanagers getting in the way.
The problem is that if you only have access to systems which will ONLY UEFI-boot, then it is difficult to change the payload to something else!
