Suggestion: Before you continue to the methods below…

  1. Enter BIOS SETUP.
  2. Locate the SATA Configuration setting. (Commonly named as "SATA Mode" or "SATA Controller Mode" or "SATA Operation" or "Configure SATA as").
  3. If the SATA Mode is set to AHCI or RAID then change it to IDE. If the SATA Mode is set to IDE then change it to AHCI.
  4. Save Changes and Exit BIOS Settings.
  5. Try to boot in Windows. If Windows doesn't start, then revert the SATA setting back to what it was and proceed to apply the methods below.

 

Notes:
1. If you receive the 0x000000e, on a system that you have used software mirroring for fault tolerance, then break the mirror first, with the DISKPART tool in Recovery Environment. Detailed instructions to do that can be found in Method-2 in this tutorial.
2. In order to resolve the 0x000000E Boot error, you need to start your computer from a Windows installation/recovery media. If you don't own a Windows Installation Media, then you can create one (corresponding to your Windows Edition and Version) directly from Microsoft.

Method 1. Fix Boot Configuration Data using BOOTREC tool.

1. Power on your PC and boot from a Windows 10 installation/recovery media.
2. At the Windows Setup screen press SHIFT + F10 to access command prompt, or choose Next –> Repair your computer –> Troubleshoot –> Advanced Options –> Command Prompt.

3. In command prompt type the following commands in order:

  • bootrec /fixmbr
  • bootrec /fixboot
  • bootrec /scanos    *

* Note: If after executing the "bootrec /scanos" command you receive that "Total identified Windows installations = 0" then give the following commands, before you continue to next step:

    • bcdedit /export C:\bcdbackup
    • C:
    • cd boot
    • attrib bcd -s -h –r
    • ren C:\boot\bcd bcd.old

4. Rebuild Boot Configuration Data:

  • bootrec /rebuildbcd

5. Press "A" to Add installation to boot list and press Enter.

bootrec rebuildbcd

6. Close all windows and restart your computer. If Windows still fails to boot, then try Method 2.

Method 2. Repair Boot Configuration Data using BCDBOOT tool.

5. Find out the volume number of the system partition * and the drive letter of OS drive,** by typing this command:

  • list volume

* At the previous step we found that the system partition is 99 MB. So, from the screenshot below, we understand that the System partition is the "Volume 2".

** The OS Drive, is the drive where the Windows installed. Commonly this is the "Volume 0", the largest volume on the list. At this example the OS drive is located at "C" drive letter.

6. Select the System partition and assign a drive letter to it. Then exit DISKPART:

  • select volume 2    *
  • assign letter=Z
  • exit
