Recently I had issues with my dual boot Linux Mint/Windows 10 instillation. It wouldn't boot. My computer would turn on and it said Error: Unknown Filesystem. Then put me at a Grub Recovery prompt. That was an easy enough fix. I just set my prefix and root to the proper partition, typed insmod normal, normal, and I could get the boot menu to pop up and load into Windows without a problem. (That's how I'm writing this message, now.)
My problem, Linux won't boot. It hangs saying:
"A start job is running for Hold until boot process finishes up (20min 00s / no limit)"
And it just sits there endlessly, not booting. During the process before it starts hanging, I get a FAILED notification while the screen is scrolling through the boot process-or whatever it scrolls through while booting. It says "Failed to start Light Display Manager."
Has anyone else had this problem? Do you know how to fix it?
