Pc was working fine with only Ubuntu. Entered BIOS on Asrock B450 gaming K4 and enabled the ultra fast boot. Now, when I start my pc, I'm faced with a gnu grub command line. Additionally, my keyboard LEDS are working but the keyboard will not do anything. What should I do? (Latest version of Ubuntu, MIGHT have another copy of Linux on my HDD which I might have missed while formatting it cause I just got a new SSD if that helps)
