Workaround I used mkusb installed in 18.04, (grub 2.02), to make the foundation of an ISO booter. ISO's in an ISO folder on usbdata partition, with casper-rw partition for persistence, (one distro only). Usbboot partition has loop mounting grub.cfg. Boots 18.04 and 19.10, both UEFI and BIOS, (I got a new power brick for my UEFI computer).
UEFI boot fails using mkusb installed in 19.10, (grub 2.04). whether 18.04 or 19.10. I think the problem is grub 2.04 myself. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1851311 Title: Grub 2.04 Out of memory error, No server error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1851311/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
