you can modify the commandline to boot interactively in grub by pressing e to edit the menu entry and specify a different root=, e.g. root=/dev/sda2.
Also you should be dropped into emergency shell and you should therefore be able to mount the root filesystem, and exit the emergency shell to continue normal boot. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1601932 Title: Xenial start problems with change UUID in fstab Status in systemd package in Ubuntu: Invalid Bug description: Xenial started correct. Now an UUID changes because a partition was reformatted. The new UUID is independent of Xenial. Xenial aborts the start, since the new UUID is not registered in fstab. Ubuntu 12.04, 14.04, 14.10 and 15.04 and 15.10 have no problems with the changed UUID. Many years ago there was this error.
