Hi Phillip, thanks for looking into this. Can you quickly explain why you think this is the case? What part of the logs shows
1. that I booted in EFI mode 2. that the disk is partitioned in BIOS mode 3. that I didn't choose "use entire disk" I don't remember what mode I booted it in, but I'm pretty sure that I chose the "use entire disk" option. After this issue, I restarted the computer and chose to go to the installer directly instead of to the live session first. I chose "use entire disk" again and the installation worked. Are the logs of a successful install saved somewhere on the computer, so I can compare the logs? ** Changed in: grub-installer (Ubuntu) Status: Invalid => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1781256 Title: installation failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1781256/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
