Windows 10 stuck in boot loop - startup repair not available

Essential Summary: In short, I've attempted a windows update that decided to botch itself into an infinite boot loop. I'm unable to break into startup repair regardless of how many times I powercycle during startup. After managing to boot through a brand new (installed at the time of the issue) windows installation flashdrive, I tried the startup repair option, which stagnated on "attempting repairs" for 30 minutes. After, I attempted to restore to a system restore point, I created before the update to be told that my machine had no restore points.

Any help is appreciated, thanks in advanced

Just in case, below is an order of events, and this is a pastebin with a detailed explanation of each event, for the sake of shortening the post.
