I'm attempting to help a friend out with Windows 10 booting to black screen. He said this started last week, which makes me think it's an automatic driver update problem. I know black screens in Win10 are a thing, but so far all the fixes I've read about haven't worked. Here's what happens:
- Regular boot results in black screen, with no mouse. Win+P DOES give the display menu bar on the right side of the screen, but none of the options actually do anything.
- Safe mode has the same issue, except that the Win+P dialog doesn't give you any options since it's safe mode.
- Low res mode results in the same, except that the menu bar now appears more centered (thus confirming that "low res" is actually working, but nothing else)
- On failed boot, the boot manager says "Failed to start...soemthing" and to look at the log files in System32/logfiles/srt/... There, the files seem present but appear corrupted, i.e won't open in text editor properly.
I also found out he tried to do a "Reset this PC" with the "keep files" option, but this failed and he doesn't recall the specific error. Might this have borked his install?
All of his necessary data was saved through a Ubuntu Live USB -> External HDD, so all experiments are now fair game. I do have reinstall media, but I'd love to know what the real problem is before I do that.
