I'm new to Ubuntu, I installed it but when I try to start it, tells me that I need to run commands from bash-like and they can be shown by tab, when I press tab shows me the commands but then I type them and nothing happens, I have to reset my computer and the same thing goes on.

This is what it says:

GNU GRUB version 1.99-21ubuntu3

Minimal bash-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists possible device or file completions.

And nothing happens from there, can you tell what I need to do now?

THANKS AGAIN!
