Windows Boot Camp MacBook has only OS X stuck in boot loop

Thank you for bringing the tool Brigadier to my attention, I was able to use it to install and access the Boot Camp Control Panel. So I was able to boot in macOS but the boot loop problem persists, now with the white Apple logo and startup chime instead of the white loading wheel. Again, pressing and holding Cmd-R for Recovery Mode or Shift for Safe Mode do nothing. I've also tried Cmd-Option-P-R and Shift-Option-Ctrl to reset NVRAM and SMC, respectively, both of which simply make the lit up black screen hang a bit longer until eventually turning off and restarting into another white Apple logo. I am still able to hold Option and boot into Windows, which is what I am using right now to write this. Is this issue necessarily related to Boot Camp at all? In any case, how can I fix it?

I am able to enter Internet Recovery, but after connecting to a Wi-Fi network, the progress bar loads, finishes, then it shuts down, the entire process starts again and I am once again prompted to connect to a Wi-Fi network.

I went to the Apple Store and they attempted to do Internet Recovery with a wired connection, to no avail. Like I described, the process finishes, then the screen goes black, powering off, then restarts and prompts an Internet Connection again. The boot loop continues. They also attempted to do a 'revive' and basically everything else possible, with no results. They said the only remaining option is to erase the drive and reinstall, which I would rather not do, since I have not backed up my files. Thanks for the help so far, at least I was able to get Windows and Boot Camp correctly functioning. For now, I will keep using my Windows MacBook and look into ways to recover my Mac OS data.
