Hi,

IIUC the machine is running Ubuntu 18.04 LTS without a GUI. Try an
Ubuntu 18.04 LTS live DVD. If you like, try to boot into a GUI first,
but if that should fail, too, boot into the command line interface and
copy the drive by command line, or just try to boot Ubuntu Mate 20.04.3
into the command line interface, instead of the GUI.
