Hello, try booting your laptop into Safe Mode. If it boots, you can copy your files to an external drive. In this mode, you can also try opening the Command Prompt and entering the following command: “dism /Online /Cleanup-Image /RestoreHealth” - it will attempt to fix errors in your system. If you still can't boot normally after this, you might need to consider reinstalling Windows.
However, if your laptop doesn't boot into Safe Mode, try removing your hard drive and connecting it to another working PC. If your drive has a corrupted file system, you can attempt to repair it using TestDisk, or simply recover your files using Disk Drill (recovers 500MB of files for free) or PhotoRec (unfortunately, it can only recover your docx files, not scriv files) or Recuva.
