Windows 8.1 / Windows 2012 eval dual 'won't boot - complicated

Windows 8.1

Asked by: Richard M.


The situation is:

I have a bitlockered 8.1 laptop that I wanted to dual boot to do some Hyper V training on using a 2012 eval vhd. Long story short...I have managed to get it stuck with it showing two Windows 2012 options in startup, no Windows 8.1 and if I try and start either of the 2012 options I get an error about not finding / error with windowssystem32winload.exe - 0xc000000f. My question is; Can I boot the laptop via an external usb, access the bitlockered drive to restore the backed up config that I created before it all went horribly wrong. I have access to my bitlocker key, but I'm getting confused on the sequence of how I access the bitlockered drive / restore the backup.

Hopefully all is not lost.

Hi Richard,

Which config file have you backed up? Are you referring to a system image backup?

It appears that some of the boot files are either missing or corrupt. Since you are unable to boot to the desktop, you will need to boot from a repair or Windows installation disc to perform any troubleshooting steps. If you have created a recovery drive in your external USB device, then you can use that to boot.

If you don’t have a USB recovery drive, then you will have to boot from the Windows 8.1 installation disc. Boot from the Windows 8.1 installation disc to enter the Windows recovery environment and then repair the boot files. Insert the Windows 8.1 installation disc and follow these steps:

  1. When your computer starts, wait for the manufacturer logo to check the option for boot menu, it will usually be F12.
  2. The boot menu key might differ with each manufacturer. If you are unable to find the boot menu key, you may refer the user manual.
  3. Restart the computer, when the manufacturer's logo is displayed, keep pressing the Boot menu option key to enter the boot menu      and change the boot option to CDDVD ROM.
  4. After you boot your computer using Windows DVD or System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.
  5. Select the correct time and Keyboard type.
  6. Click Repair your computer in the lower left corner.
  7. Click on Troubleshooting, Advanced option and then click Automatic repair.

If the Automatic repair didn’t fix the issue, then manually repair the boot files as explained below:

  1. Follow the same steps mentioned above to get to the ‘Advanced options’ screen.
  2. Click on “command prompt’, type ‘Bootrec.exe’ and press enter.
  3. Now you will see a list of options that you can use with the bootrec tool.
  4. Type “Bootrec.exe/ScanOS’ and press enter to see a list of Windows installations. It will also display a list of entries that are not in the BCD store.
  5. Type ‘Bootrec.exe/RebuildBcd’ and press enter to scan and add Windows installations that are not included in the BCD store.

Try these steps and let us know the results.
