Public bug reported: I had ubuntu installed on my main hard drive, sda, and wanted to make an external hard drive have its own ubuntu installation that was bootable.
I plugged it in, and used the live USB to install to it. (20.04.4 LTS ubuntu desktop) In ubiquity 20.04.15.17, on the partition manager, I selected something else, and made the / partition on the external hard drive sdb (different make and capacity so it was definitely the right hard drive). I also added a swap partition to it too. I changed the 'device for boot loader installation' to sdb also and finished installation. After installing, the external hard drive was not bootable. I unplugged it, and tried to boot to my normal ubuntu desktop, which was also now broken. ** Affects: ubuntu Importance: Undecided Status: New ** Tags: ubiquity -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1955157 Title: Ubuntu installer overwrote the wrong hard drive bootloader To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1955157/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
