Hello the wise ones,
I was remotely updating Ubuntu on my granny's computer from 20.04 to 22.04. the installation succeeded, the computer restarted and then we saw the the usual grub menu:
and after that I see a black screen with an underscore in the top left corner.
Here are the options for advanced boot options for Ubuntu:
selecting the first one gets me black screen with an underscore in the top left corner.
second one gets recovery mode stuff.
the 3rd one boots ubuntu normally.
the 4th one I did not try.
after managing to start Ubuntu with the third option, I decided to restart it to see what happens. Turns out that we get the same thing (i.e. it doesn't work with the default Ubuntu option from the grub menu)
how to solve this problem?
thank you in advance!
P.S. My search for answers came up with various things including disabling Fast Boot and Secure Boot. I disabled Fast boot option and tried to disable Secure Boot option, but did not have an option to do so:
