I've put off doing a reinstall many times. Every time I thought I've messed my system up beyond repair I've somehow managed to bring it back. My system is only stable on LTS kernel and if I try to switch to current I am presented with a black screen, it's lit up, just black. I thought it was a condition of the abuse I had put my system through. I decided to do a reinstall, and the usb drive boots to the exact same problem. I tried all 3 boot options, and added nomodeset to the debug option; and none of them boot far enough to even load a tty. I get no debug messages, absolutely nothing; just sits at a black lit up screen.
