Booting ISO Files using GRUB 2
I believe another concern of this Bug is the booting of Groovy ISO files directly using GRUB 2.
Programs that use this method include Ventoy. YUMI and MultiBootUSB.
I mostly use a BIOS-UEFI Template image developed by sudodus, see: https://askubuntu.com/questions/1269462/bios-uefi-template-image-for-booting-iso-files
BIOS mode booting of ISO files now appears to work okay with the latest Groovy Daily ISO.
The only way I have been able to get UEFI mode booting to work is by using "nomodeset" which results in a distorted desktop.
This also works for Ventoy, however YUMI BIOS/GRUB and MultiBootUSB are not yet working with 20.10.
