If you want to install or operate a Linux system that won't boot properly you can start the system from a USB and then change root access from the USB system over to the broken system. It's a bit fiddly, but here's a convenient and quick method all in one line of bash:
sudo mount /dev/mapper/vgmint-root /mnt && for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done && sudo chroot /mnt
This mounts the root drive on the main system, then mounts the main system's various main system directories (dev, dev/pts, proc, sys, run) and then changes root to the main system's mnt directory.
At that point, your command line is talking to the main computer. Commands are executed on the main machine, not the USB.
