The name of the operating system is Ubuntu, not Ubantu

What exactly do you now see when booting the computer?

A possible way to access the data on your hard disk is booting an Ubuntu installer in the "Try Ubuntu without installing" mode. This allows copying the data to an external device.

Can you help with this problem?
