I have the USB ready, but I am scared af

Sorry for posting like 3 things here, you guys might be annoyed by me returning here a lot, but I have a hackintosh USB ready and I am scared. What if it fails to boot and I am stuck on a black screen with code running across it forever, or if my computer somehow erases itself or something, is there any way I could test my USB to see if it works? :(
