I'm on a first generation Surface Book, Windows 10 pro, installed all latest updates just prior to issue arising. So, long story short, yesterday I flipped on Bitlocker for the first time. I went through all the prompts, choosing my key to be stored on a USB drive and choosing to "print a paper copy) of recovery key, which I did and which I have right here. After a couple more prompts, a message popped up telling me to restart to encrypt, so I did... and my computer has been completely locked with Bitlocker ever since. When I first start computer, it first comes to a blue screen that says "Bitlocker - Plug in USB drive that has Bitlocker key", but no matter how many times I plug in my usb (the same one I used when Bitlocker was being initially setup yesterday), Bitlocker doesn't recognize that action or respond in any way. I've tried to reboot and try again several times, always the same result. Next, I hit my only other option: "Press Esc or Windows key for recovery", and I'm taken to another blue screen that gives me the option to unlock using either the recovery key or usb AGAIN. Now when I attempt to unlock using usb, Bitlocker says that no key file exists on device. Then, when I try to open it using the correct recovery key, and trust me, I'm putting that in correctly, it will likewise decline me access, saying my recovery key doesn't work either... but I'm entering the correct key!! I'm 100% sure of it! Interestingly, if I access command prompt and check the bitlocker status for each drive, it says "locked", but almost every other field is listed as "unknown" on my main C: drive, whereas the other two unaffected drives are unlocked with every field full of info. Lastly, when using command prompt to reveal the applicable "key protectors", it spits out an "External Key", an "External Key File Name", and a "Numerical Password ID", but no 48-digit recovery key listed anywhere. It's almost as if there is no key somehow. Idk, I just want this bitlocker unlocked so that I can turn it off and never see it again. Can someone please help me figure this out? Thanks in advance. P.S., if you're interested in seeing this in action, here's a link to a short, 8-minute video where I run through all the steps right there on screen to show what it looks like: https://photos.app.goo.gl/rC3ke9qZkfxuX13a7
