I have been able to successfully create a USB drive that boots Ubuntu 18 ISO images. The web site that I used for information is https://www.splitbrain.org/blog/2012-12/22-the_ultimate_usb_stick_setup .
I had to make a few changes to grub.cfg. I will attach a zip file containing the contents of the usb drive with empty files in stead of complete iso files. I have not tested the drive with various hardware configurations or BIOS settings, but it should have enough information to be able to build an application to easily create a tool to build the USB drive. The partition is FAT32 and contains an (msftdata) flag - which might be left over from using Rufus on Windows (partion name is "Microsoft Basic Data"). However, I think performing a grub install should work as well. ** Attachment added: "Contents required on USB drive that allows booting ISO images" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798251/+attachment/5202059/+files/usb-boot-iso.zip -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1798251 Title: Cannot boot from USB pen drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1798251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
