[Bug 1851311] Re: Grub 2.04 Out of memory error, No server error

[sudodus]

This is actually going back to my original usage of usb-pack-efi, that
is described in post #6 and the following posts of this thread at the
Ubuntu Forums,

https://ubuntuforums.org/showthread.php?t=2259682&p=13300523#post13300523

This grub system works in UEFI and BIOS mode. It is developed from a
multiboot system for UEFI by Andre Rodovalho.

I will think about including such an option in mkusb. Please consider
that you and Sundar are welcome to use this piece of FOSS software in
tools that you create and maintain :-)

  Trying to loop mount ISO.

  Installed grub 2.04 to flash drive in UEFI mode from 19.10
