[SOLVED] Mac stuck in windows boot

[Harv0118]

I tried downloading windows 10 onto a Mac, now it's stuck in an endless loop of booting with the OS X boot noise, black screening, showing a windows loading screen, blue screening, and then repeating that process. I have a USB with a fresh install of OS X, but I only have a windows keyboard for it because the Bluetooth one disconnected, therefor I cannot press option on the keyboard to select the boot device. Any ideas?

I believe the Option key maps to the Alt key if you're using a PC keyboard.
