I have for a while been dual booting a stable install alongside a development install even on external drives. This does not have the grub panicing if a drive is missing in bios mode with a missing drive and goes into recovery mode with even less options. Granted the choosing wrong partition can be a problem with catostrophic results. Although I am not sure this is good for others but I memorize which partition not to touch.
Also hardware affecting bugs can happen in the installer but maybe not as often see bug #1675127 which has quite specific of not being connected over ethernet and have a broadcom 4322 that the installer sees and does not have drivers for in every ubuntu release I have used except the broadcom proprietary ones. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1687333 Title: Provide a method for installing Ubuntu directly into an USB drive To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1687333/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
