Oops, After a little more experimenting, it appears that it is the version of Ubuntu that mkusb uses to create the persistent drive that determines the version of grub, not the version of Ubuntu mkusb is installed in. I guess that this should have been obvious. I created an ISO booter foundation using mkusb installed in 18.04 using a 19.10 ISO. I added both 18.04 and 19.10 ISOs to the ISO folder on the usbdata NTFS partition. Both had problems booting in UEFI as mentioned above, they uses grub 2.04 I then created another ISO booter foundation using mkusb installed in 19.10 using a 18.04 ISO. I added both 18.04 and 19.10 ISOs to the ISO folder. Both booted fine in UEFI mode, they used grub 2.02. I will try duplicate my findings tomorrow.
