Summary
Many people have asked me 'how can I boot to E2B and select a UEFI payload, if I only have one UEFI-only system'?This is an (old) blog post - Easy2Boot v2 now includes agFM UEFI boot files, so you can directly UEFI-boot to any payload or ISO file from the agFM menu system. You can also add Ventoy too!
Due to some systems have buggy BIOSes, it is best to have two E2B USB drives, one for UEFI booting and payloads and the other for MBR booting and MBR payloads.
SWITCH_E2B.exe is a Windows utility that allows you to switch .imgPTN images without booting in MBR-mode.
