Removing everything and starting over with no access.

I installed a Success ful 10.12 on my computer but ran into issues with it restarting after prompting shutdown.

I followed a guide on a forum and after adding some kext files my Mac partition loads the motherboard screen then shows a bunch of +++++++++++. Is there a way to wipe everything and start over without getting into the system? Any option from clover other than windows locks up.
