There are a few steps you can try to fix a corrupted Windows boot:
- Check the boot order in your BIOS: Make sure that your computer is set to boot from the hard drive containing the Windows installation.
- Use the Windows Startup Repair tool: You can use this tool to scan your system for errors and attempt to fix any problems it finds. To access the Startup Repair tool, you’ll need to boot from your Windows installation media (e.g. a Windows installation DVD or USB drive).
- Use the chkdsk command: This command can help fix errors on your hard drive that might be causing boot problems. To use it, you’ll need to boot from your installation media and then access the Command Prompt. Type the following command and press Enter:
chkdsk C: /f /r
- Use the bootrec command: This command can help fix errors with the boot process itself. To use it, you’ll need to boot from your installation media and then access the Command Prompt. Type the following commands and press Enter after each one:
bootrec /fixmbr
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
Details:
bootrec /fixmbr: Repairs the Master Boot Record (MBR) on the drive containing the Windows installation.
bootrec /fixboot: Writes a new boot sector to the drive containing the Windows installation.
bootrec /scanos: Scans the drive for Windows installations and adds them to the BCD store.
bootrec /rebuildbcd: Scans the drive for Windows installations and allows you to choose which ones to add to the BCD store.Reinstall Windows: If none of the above steps have worked, you may need to reinstall Windows. Be sure to back up any important data before doing this, as the process will erase everything on your hard drive.
