HP 15 (ac-101ur model, just in case) laptop owner here. Booted Ubuntu Groovy thumb drive using Legacy method, *no* UEFI whatsoever.
When I first tried to install Ubuntu, replacing Windows (as I now own a new laptop), Ubiquity yelled "No UEFI partition found" - this bug didn't occur in earlier versions of Ubuntu (Bionic and Disco, as tested) When I *manually* converted hard drive's partition table to 'msdos' in GParted, and trying to manually partition the system, I also get the same "No UEFI partition found" error. After discarding this error, installation decided to fail at "grub- install" failed. When I looked at the installation console, I did not actually see any bad signs of GRUB failure at all - it just said "Installation complete without error" and installer decided to fail. I don't currently have logs I am in process of testing workaround posted in Comment #8 and Comment #9. I'll update this comment (or create a new one) if something useful happens. Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1893964 Title: Installation of Ubuntu Groovy with manual partitioning without an EFI System Partition fails on 'grub-install /dev/sda' even on non-UEFI systems To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1893964/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
