Same happens to me on an Ubuntu 21.04 beta iso. It boots perfectly on an EFI laptop but fails on my PC with BIOS. I tried creating the bootable usb drive with startup-disk-creator and get the same results too with gnome-disks using the restore disk image.
And it is not the first time I see that. I tried with several daily builds of Hirsute Hippo and always fails.
I get the same error message too: Error can't find grub_platform.
I think that is clearly a bug. But I don't know against which package should be filled.
