Data Recovery:

If your computer boots normally, back up your files to another device using professional backup software (like MiniTool ShadowMaker). A free trial is often available. If your computer won't boot, use data recovery software such as MiniTool Power Data Recovery. This software can recover files from unbootable, formatted, or damaged drives. You'll need to create a bootable media using the software's bootable builder to access your files.
