To fix a corrupted boot, first, try restarting your computer and accessing the Advanced Startup Options (ASO) screen. From there, select 'Troubleshoot', then 'Advanced Options,' and finally, 'Startup Repair.' If that doesn't work, boot from a Windows installation media, select 'Repair your computer,' and then use the Command Prompt to run `bootrec /fixmbr`, `bootrec /fixboot`, and `bootrec /rebuildbcd` commands. These steps aim to repair the Master Boot Record (MBR), boot sector, and Boot Configuration Data (BCD), respectively.
