I recently downloaded Ubuntu 18.04 from the official Ubuntu website. I used Etcher to convert my flash drive into a bootable Ubuntu live USB. I installed Ubuntu 18.04 on my SSD, and later when the screen said to reboot, Ubuntu was unable to load. Random boot messages appeared saying there was some error.
Every time I tried to install Ubuntu the same thing happened. I went for the dual boot for the next time, but after getting that error I removed Windows from the SSD and tried to clean install Ubuntu, but the same thing happened.
