A few days ago, I accidentally replaced my desktop in Mint 18 with a virtual console with an errant keystroke. Not having an obvious way to reverse the changes, I logged in and typed
exit to exit the console and go back to the desktop. Instead, the computer rebooted, and I lost God-only-knows-how-much unsaved work.
After showing the Mint logo and flashing a message underneath it far too quickly to read, the computer now boots only to a black screen. By pressing
esc during reboot, I can get to a Startup Menu. I ran disk checks and memory checks using it, and they all came up clean. None of the other options in this menu help. I have no idea what to do.
The screen is clearly receiving power, and the black screen that it boots to shows a dash or underscore in the top right corner.
How do I get my computer back? It's an HP Pavilion laptop.
