So in this video, I crash Windows 10 on purpose to see if Startup Repair can fix it! However it turned out to be an EPIC FAIL! I tried it twice in this video, in which both times it FAILED! However I think because it was the 10240 build of Windows 10! The newer build would work I think.. that's if it isn't destroyed too badly! So if you guys are still running the older build, I would update as soon as possible! Also it is much improved anyways!
