How To Fix Boot/BCD 0xc000000f Error Windows 7

Cause and Fix

The most likely cause of this error is that you tried to dual boot two operating systems and then later decided to remove one. This inadvertently may have deleted the bcd boot store. The trick here is to run the above commands in the right order and set your boot partition to active. Let’s get started.

Make sure your boot partition is set to Active

Boot from your DVD and choose the repair option. From the recovery console type “diskpart” and press enter and then type “list disk” to get a list of physical disks installed.

In the example here I only have one disk in my machine, if you have more than one identify the disk which has the Windows boot partition on it and then select it. Select it by typing “select disk 0” (in my case). Now type “list partition”. The Windows 7 boot partition is a 200 MB primary partition. As you can see here it was on disk 0. Select it by typing “select partition 2” or whichever number matches your 200MB partition.

Now type “detail partition” and look where it says “Active”. If it says yes then move onto the next section otherwise type “Active” and press enter, Windows should report the partition is now marked as active. Now reboot and boot into the recovery console again.

Repair the MBR and boot sectors

From the recovery console run these commands in this order:

§  bootrec /fixmbr

§  bootrec /fixboot

Now reboot the machine again into the recovery console and type “bcdboot path to your windows folder“.  Your windows folder will normally be c:\windows but in the recovery console it may show up as D:\windows so make sure you get the path right. In my case it was “bcdboot d:\windows”. This will will build a new bcd boot store and copy over all boot files needed to boot. Now reboot your machine one last time and it should work. If it doesn’t run the two bootrec commands again.

If you have any additional operating systems you want to add use the bootrec /scanos command.
