Laptops boot to Startup Repair when there are corrupt startup files on the hard drive. Allow the laptop to complete the process. Then, sign into Windows and do the following to prevent it from recurring:
Open a command prompt window. Type ***CMD*** into the Search bar. Right-click the Command Prompt option and select “Run as administrator”. Copy and paste this command into the window: ***dism /online /cleanup-image /restorehealth && sfc /scannow***
These commands should repair the corrupt files.
