I open up my laptop today and saw a light blue screen that said "All of your files are still here", but seemed frozen on that, so I restarted. Then, my would just boot up to a perpetual black screen and nothing more. Next, while booting up, I held the start button, the windows button, and b, and this has gotten me to my desktop, which seems normal, except I can't access my start bar at all and Windows Edge has disappeared completely. I ran the sfc / scannow in powershell and it told me there were no issues. I don't know what to do. Please help. Thank you.
