Recently I've had login loop problem, even after trying several solutions given in the forums. I ended up installing Gnome as suggested here as Solution 3.
After rebooting, the desktop changed to Ubuntu Gnome, but still didn't solve the loop problem. then I went to BIOS and changed the boot priority to another option, didn't work, then again came back to previous priority and now I can't even access to that login screen. When I switch the computer on I have purple screen suggesting *Ubuntu, Advanced options for Ubuntu, and System setup. Once I hit *Ubuntu it goes through some process Then the screen gets dark for about 4 seconds and quickly shows up And this repeats infinitely.
I think I corrupted the Ubuntu system by trying too many things.
How can I solve this case? If there is no way,How can I uninstall Ubuntu from my computer without damaging Windows system?
Thank you for your time and advice!
sudo mount /dev/sda6 /mnt/boot/efi
it is showing mount: mount point /mnt/boot/efi doesn't exist Are you taking into consideration that I am not able to write these code blocks to normal terminal because of flickering of the terminal. I am writing these things after forcing the terminal to show up every time by pressing ctrl+alt+f1.
