@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?
