Windows Boot Manager error 0xc000000e
Info: The boot selection failed because a required device is inaccessible.
Cause
Disk signature is a unique identifier Windows uses to remember drive letter assignments. If this identifier gets changed or corrupted, such as in situations of disk cloning or partition removal, a new signature would need to be created so Windows can re-identify and regenerate drive mappings; however, the WIndow's boot manager would also need to be directed to this new information or the above error is generated.
Resolution
On systems where the disk signature/ID has not been changed but are still in queue to be so, follow the steps below to change the disk signature and update the Windows Boot manager:
1. Open a CMD prompt with administrator privileges.
2. Run the following set of commands: DISKPART -> SELECT DISK 0 -> UNIQUEID DISK ID=
3. Quit DISKPART stay within the command prompt.
4. Enter the following commands, one at a time, in the command prompt pressing
a. bcdboot c:\windows /s c:
b. bcdedit /set {DEFAULT} device partition=c:
c. bcdedit /set {DEFAULT} osdevice partition=c:
d. bcdedit /set {BOOTMGR} device partition=c:
5. Close the command prompt.
6. Reboot.
