@sudodus: Made a persistent 4GB flash drive using mkusb menu item usb-pack-efi with 19.10. Used this drive to make a second 4GB flash drive using mkusb menu item usb-pack-efi with 19.10. (Just to make sure grub 2.02 had no way to sneak in). Deleted ISO9660 partiton #4, stretched Casper-rw partition #5 into place and expanded usbdata NTFS partition #1. Dropped 19.10 ISO into iso folder on NTFS partition. Updated grub.cfg on usbboot partition #2 to loopmount the 19.10 ISO. Booted in BIOS using grub 2.04 Booted in UEFI using grub 2.02~Beta2
This solution works for me. I am impressed. Is there way to retro fit this to a working system so sundar-ima can use it to boot ISOs from his internal dive? I wonder how Qemu is doing with this bug? Mkusb would work fine for setting up a small SSD, as either Full or Persistent install for booting ISOs, but my SSD booting option seems to be missing?
