Comment 105 for bug 1886148

Thank you again for all of your testing. I've made some further changes to the xorriso options which should bring the image more in line with standards, following xorriso upstream guidance and I have again boot tested on {BIOS,UEFI} {cdrom,hd} under KVM. Please give http://cdimage.ubuntu.com/ubuntu/daily-live/20200915.5/ a whirl and see if it works any better for you. The changes made are specific to the UEFI boot options, so BIOS boot testing is not required.

It has always been the intent to get UEFI boot working again on these systems, it was just non-obvious how to get this working while moving BIOS boot to GRUB since the previous hybrid mode depended on isolinux-specific options to xorriso.

The partition table on the current image looks like what we are looking for and should generally fare better with diverse UEFI implementations.
