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.
如果您的Windows 10啟動時提示BCD損壞,您可以嘗試以下步驟來修復它:
1. 在Windows 10安裝媒體中進入“修復你的計算機”選項。您可以使用DVD、USB閃存驅(qū)動器或其他啟動介質(zhì)。
2. 選擇“故障排除”>“高級選項”>“命令提示符”。輸入以下命令:
`bootrec.exe /fixmbr`
`bootrec.exe /fixboot`
`bootrec.exe /rebuildbcd`
3. 重啟計算機并檢查是否解決了問題。
如果這些步驟無法解決問題,您可能需要重新安裝Windows 10或者求助于專業(yè)技術支持。
以下為Win10 bcd修復命令:
1. 打開一個管理員權限的命令提示符,方法為右鍵單擊‘開始’菜單,選擇‘命令提示符(管理員)’。
2. 輸入以下命令以備份原有的引導文件
bcdedit /export C:\BCD_Backup
3. 依次執(zhí)行以下命令:
bootrec /fixboot
bootrec /scanos
bootrec /rebuildbcd
4. 如果上述命令無法修復引導文件,可以執(zhí)行以下命令:
bootrec /repairbcd
bootrec /fixmbr
bootrec /fixboot
5. 最后輸入以下命令重新開始計算機:
shutdown /r /t 0
以上是Win10 bcd修復命令,希望對您有所幫助。注意:在執(zhí)行這些命令之前,請備份數(shù)據(jù)以及引導分區(qū),以防數(shù)據(jù)損失。
為了修復Windows 7的BCD,請按照以下步驟操作:

8. 如果命令提示您添加一個新的操作系統(tǒng),請鍵入Y并按Enter鍵,然后繼續(xù)操作。
9. 重啟計算機并移除安裝盤。
這些步驟應該能夠成功修復Windows 7的BCD。如果仍然遇到問題,請考慮查看更詳細的指南或聯(lián)系計算機專家以獲取更好的支持。
1. 在Windows 10的安裝媒體(如USB安裝盤或恢復磁盤)中進入“修復你的電腦”。
2. 選擇“疑難解答”>“高級選項”>“命令提示符”。
3. 在命令提示符中輸入“bootrec /fixmbr”、“bootrec /fixboot”,以及“bootrec /rebuildbcd”。
4. 重啟計算機,檢查問題是否已解決。
