I attempted to upgrade from macOS Sierra to High Sierra on my late 2010 MacBook Pro and it failed part way through the installation. On restarting it flashes a folder with a question mark on a white screen.
I boot into recovery with Command + r, go to Disk Utility, perform First Aid and both the internal hard disk and the disk image titled "OS Base System" checks out fine with no issues. I tried unmounting and mounting the hard disk. It still doesn't show any option to choose the disk as the startup disk.
I tried reinstalling macOS from the utility menu and after a long pause it brings up Terms and Conditions. After accepting them, it says it has begun and shows 8 minutes remaining. After staying at 8 minutes remaining for a few minutes it goes to 14h 22m and stays there and has been so for a few hours.
No errors are popping up, and while I don't know much about this stuff, it appears from the installer log it's having some troubles, various errors finding/creating information. I've restarted several times in between all of this stuff and nothing has worked.
I don't believe I have a backup less than two years old and none are showing up as options. How do I resolve this issue?
