There are 2 issues here so don't jump the gun with a quick answer. I'm running Windows 10 and upon boot I got the below message (1834) no matter how many times I restarted. I finally hit the "advanced options" and selected restore to a previous date and it showed a restore point in December (which I didn't know I had) and a critical update a few days ago with the KB # but I didn't take a pic of that screen darn it. The restore point put me back in business. Wondering if I could find that same window I've searched for "restore" in several ways and it always brings up the pic in 1835. Ridiculous. Even if I click restore, it says I have no Windows 7 points to restore. Thankfully the "advanced options" led me to a restore option but now unfound. I've only had Windows 10 on this drive from day one yet it gives me all these other options now to restore to. Evidently the '"critical update" a day ago shut me down. One of the options in advanced gave me a # to call and to tell them the error message is INACCESSIBLE BOOT DEVICE and they could help me. That's like saying my drive was bad vs Windows screwed up.
