[RESOLVED] Unable to book up after Kext Installation

[wlit]

My system is no longer able to boot up after following the steps from thread below in comment# 4. Can some please take a look at attached screenshot and provide some guidance?

Bluetooth (BCM94352Z) isn't working on GA-H170N-WIFI #4

When I try to reinstall Sierra from USB, I am suck at the "Prohibited" sign on boot. Any help is appreciated. Thank you!

Resolved by using Window Bootup disk to delete the partition and do a clean install.
