Rebuild the BCD using bootrec.exe

by | posted in: Allgemein | 0

Solution 1. Rebuild the BCD using bootrec.exe

This fix needs your Windows installation disc so you can access bootrec.exe. This is a tool built in Windows RE (Windows Recovery Environment). bootrec is a program that can repair boot configuration data and master boot records.

  1. Insert your Windows install disc
  2. Restart your computer and boot from the disc
  3. Press any key when the “Press any key to boot from CD or DVD” message appears
  4. Select Repair your computer after you select your language, time and keyboard method preferences
  5. Select your Windows installation drive (which is usually C:\) and click Next
  6. Choose Command Prompt when the System Recovery Options box appears
  7. Type in this command: bootrec /rebuildbcd
  8. Press Enter

Wait for the process to wait, remove the disc and restart your computer

NOTE: In case system partition is corrupted, do these in place of step 7:

  1. attrib -r -s -h c:\boot\bcd – unhide BCD so it can be deleted
  2. del c:\boot\bcd – delete the current BCD
  3. bcdboot C:\windows – create a new BCD on the C drive

Solution 2. This was on Microsoft’s official website :

If rebuilding the BCD does not resolve the startup issue, you can export and delete the BCD, and then run this option again. By doing this, you make sure that the BCD is completely rebuilt. To do this, type the following commands at the Windows RE command prompt:

· bcdedit /export C:\BCD_Backup

· c:

· cd boot

· attrib bcd -s -h -r

· ren c:\boot\bcd bcd.old

· bootrec /RebuildBcd

Hope it helps.
