alacrans help topic
G4E offers a boot menu that's easy to customize. Examples are provided in the threads above.
Although it is in developement, main functions are useable right now: booting ISO / WIM / VHD.
Note:
You can use G4E only if you are willing and able to bypass "Secure Boot".
Tested on Windows 10 21H1 (UEFI-mode:GPT and MBR). Real workstation and VirtualBox machine.
To edit G4E menu there is Grubmenu-xTender available.
Take a look at this related topic where a short desciption of usage is given.
