So I’ve been facing a weird issue.
Recently I used Boot Camp to install windows on my Mac (Max book pro 13 inch late 2020) and it was working perfectly.
But suddenly today when I tried switching to MacOS from windows, the mac won’t boot up.
When booting up the screen turns grey for a bit and then goes out and it keeps going on like this.
Luckily the Mac will boot up with windows…
Unfortunately it didn’t work…
And besides, now instead of the blank grey screen my Mac shows me a circuiting loading icon, when trying to boot up.
I have tried internet recovery, but I just got into an loop of recoveries which seemed to not have an end.
I even tried uninstalling windows and reinstalling it, but it didn’t work either.

I think this still applies to the macOS portion of the machine, but that's just a guess: If your Mac doesn't start up all the way – Apple Support (UK)
"Blank (empty) Screen"
Mac won’t boot up with OsX but with windows
