I was trying to upgrade ubuntu version from 20.04 lts to its newest version 20.10 . I was watching the upgrading process but left it for 10 mintutes or so..when I came back it showed me the login screen . I entered my password and pressed ENTER but it didn't start and was completely blank for 5 minutes so I shut it off.
Now When I boot my computer I can see the GRUB menu as usual.
I tried to enter ubuntu but it doesn't work just blank .
So I tried opening the terminal using Ctl+Alt+T and F-keys as well. When I try to boot it in recovery mode it the same thing happens. I don't get the normal option menu that comes in recovery mode.
NOTE: I am booting in insecure mode .
I tried it all..can anybody please help me out with this ?
