Why then are you bothering to make an ISO image ? The ISO 9660 format is
useful only on optical media. You can use a USB flash drive just like

The iso boots with no problems from a USB flash drive on machines using
BIOS.
It is not the ISO part that boots, it is the MBR part of an hybrid
image. A pure ISO filesystem is not bootable on a USB flash drive, only
on an optical disc.
I need it to also boot on machines using UEFI.
Create an EFI partition, mount it as /boot/efi and install GRUB with
--removable.
