Q: Can't escape reboot loop

Ok so what happened was using BootCamp version 6 drivers for my Windows 10 installed with Boot Camp. After completing the installation I had to restart the system what I did and it kept looping me all the way. First of all I've heard louder Mac power on noise, then more quiet one two times. There was windows blue logo aswell. After trying to restart whole windows operating system unsuccessfully I see no more blue logo, I can't access content menu with troubleshooting no nothing. All I have on screen when turning on my iMac is constant power on noise, one loud and two times in the row quiet. It keeps repeating, F8 doesn't work, I'm clueless.

iMac, iOS 9.3.5

If you disconnect the power adapter, does Windows boot with a proper screen display.

This is usually a problem with GPU drivers. What year/model is your Mac?

I did not disconnect nothing! Windows does not boot with a proper screen display, it is black, yet underlightened slightly. It's late 2013, 21"5 inch. Had none problems with GPU yet.

From iMac (21.5-inch, Late 2013) - Technical Specifications, do you have the Intel GPU or the nVidia GPU?

Status update : I've unplugged power adapter, plugged in again, and while computer was starting I've held Option + Command + P + R what took me to OSX startup. Consider problem gone.

NVRAM Reset will switch back to default OS, OSX in your case. Can you test switching to Windows and test, if it works?

I need to ask for forgiveness since I did uninstalation with Boot Camp of the whole system. It was too much for me already, spent around 30 hours trying to make bootcamp drivers work. Definitely not enjoyable.
