windows10bcd修復(fù)

There are a few ways to repair or rebuild the boot configuration data (BCD) on a Windows 10 computer, depending on the specific issue and level of access to the system. Here are some possible steps you can try:

1. Use automatic repair

If your Windows 10 computer cannot start up properly due to BCD errors, you can use the automatic repair feature built into the operating system. This feature can help diagnose and fix startup issues, including problems with BCD. Here's how to perform an automatic repair:

1. Insert the Windows 10 installation media (such as a DVD or USB flash drive).

2. Restart your computer and boot from the installation media.

3. Select your language preferences and click Next.

4. Click on the "Repair your computer" option in the lower left corner.

5. Choose "Troubleshoot" and then "Advanced options."

6. Select "Startup Repair" and follow the on-screen instructions to complete the repair process.

Note that the exact steps may vary depending on your system and installation media.

2. Use bootrec commands

If the automatic repair option doesn't work or you have more advanced issues with BCD, you can use the command prompt and run some bootrec commands to repair or rebuild the BCD. Here are the steps:

1. Boot your computer from the Windows 10 installation media as described above.

2. Choose "Command Prompt" from the advanced options screen.

3. Type the following commands one at a time and press Enter after each one:

bootrec /fixmbr

bootrec /fixboot

bootrec /scanos

bootrec /rebuildbcd

4. Follow the prompts and answer "Y" or "Yes" if prompted to add the Windows installation to the BCD.

5. Restart your computer and check if the BCD issues have been resolved.

3. Use recovery options

If your Windows 10 system has a recovery partition (or you have created a system image or backup), you can use the recovery options to restore your computer to a previous state before the BCD errors occurred. Here's how to do it:

1. Restart your computer and repeatedly tap the F11 key (or another key depending on your system) during boot to access the recovery options.

2. Choose "Troubleshoot" and then "Advanced options."

3. Select "System Restore" or "System Image Recovery" and follow the on-screen instructions to restore your system to a previous state when it was working properly.

4. Check if the BCD issues have been resolved after the restore process is complete.

Note that system restore or system image recovery may erase some of your recent data, so make sure to back up your important files before attempting this option.

In any case, if you're not comfortable or confident with these steps, you may want to seek professional help or contact Microsoft support for further assistance.
