This looks like a firmware issue. If you install Ubuntu from our install images, it WILL register itself with the firmware as the first boot option. It never registers itself as the second option. If you are seeing it as the second option, this is because your firmware is overriding the setting and introducing another boot option that is invisible to Ubuntu from the firmware variables.
To change your system to not boot first from network, you will need to go into your firmware settings and disable it. You can verify this by checking the output of the command 'efibootmgr -v' both after the install has completed but before you've rebooted, and after you've rebooted into the newly-installed system. ** Package changed: grub (Ubuntu) => grub2 (Ubuntu) ** Changed in: grub2 (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968145 Title: Ubuntu won't change itself to first boot option in UEFI Boot Order after installing Ubuntu22.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1968145/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
