I've acquired an old laptop (Acer TravelMate 4050 with an Italian keyboard) that boots up with the following options:

Ubuntu, with Linux 3.0.0-12-generic

Ubuntu, with Linux 3.0.0-12-generic (recovery mode)

Memory test (memtest86+)

Memory test (memtest86+, serial console 115200)

When I choose the first option, the screen just goes blank with a flashing cursor. But I can go into grub> command mode by typing 'c'.

Now, I want to know what operating system is installed, and the files stored on my computer, so how do I do this?

What can I do to maximise the use of this computer in its current state?
