My computer boots to a black screen, what options do I have to fix it?
I'm a complete noob to Ubuntu/Linux. Obviously Ubuntu is having trouble with my NVIDIA card and thus produces graphics glitches and craziness at the login screen. I tried pressing SHIFT on bootup in order to boot with nomodeset but didn't get any Grub menu. I can however boot my live USB stick with nomodeset. Can I install the proper GPU drivers (or restore the Grub menu) onto my HDD-installed Ubuntu from the live USB somehow? And if so, how?
If you have a solution, please explain it to me like I'm five - I'm really not proficient at this stuff at all! Thanks in advance for any advice!
