Bootup freezes after 10.13.6 update

I updated High Sierra from the app store to 10.13.6 and now I get the apple logo with a progress bar that goes up to about 90 percent and freezes.

I looked into troubleshooting this and read suggestions to update clover and all my kexts - I'm not sure how to go about this now that I only have access to the windows partition of my machine? (I'm a noob, shoot me)

If I were to start again from scratch, is there an easy way to do so without losing the data on my Macintosh HD partition?

My hardware

TIA
