Windows 10 finally booted to desktop after 4 hours of freezing on boot. What do I do so that this doesn't happen tomorrow?

My computer restarted overnight (assuming from an update) and froze on the boot screen where it shows the motherboard logo. It's also been freezing at the 'Preparing Automatic Repair' screen about 9/10 times.

I've tried resetting the CMOS by unplugging the power cord and holding down the power button, but it didn't help.

The few times I managed to access the troubleshooting tools and the command prompt I tried the bootrec /fixboot commands but I ran into the problem of "Path not found" at the attrib c:\boot\bcd -h -r -s step. On the final restart before I was about to plug in the bootable USB to reinstall windows, it booted to desktop with everything working as normal.

I feel like this is only temporary and I'll run into the same problem the next time it restarts. What do I need to check/fix so that this problem doesn't happen again? Or do I just need to bite the bullet and do a fresh install of Windows?

(I'm not sure if this was due to my fiddling around but I now have 2 recovery partitions on my C drive, and an addition EFI System Partition on an external HDD.)
