Public bug reported: I think the problem is the same as described here: https://discourse.ubuntubudgie.org/t/20-10-grub-error-can-t-find- command-grub-platform/4292. I can see prior to grub menu, briefly, the same error: Error can't find grub_platform. After the solution described below, this error is not showed and the system is able to boot.
I try making the live usb using startup disk creator and with gnome- disks --> Restore disk image and get the same results. The live-usb has a gpt partition table instead of mbr like 20.04 live- usb has. That implies, I think, that the first one does not boot on BIOS systems and the second does. I try the same live-usb on an EFI laptop and it boots perfectly (perhaps it takes long time). If I try the solution described here: https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1905491/comments/8 then it works. I think it is the same bug but I reported it again because, I don't know exactly why, it was tagged as invalid, but I think it is a bug and it must be solved because it's not normal that users with BIOS pc's have to do all this procedure to get a live session working.
