Windows 7 Disk Clone: Fixing Boot Manager Errors after Cloning Entire Disk


I cloned my Dell XPS laptop’s 500GB hard drive to a 240GB SSD. The clone took over 5 hours to complete successfully. After rebooting, I received the following:

Windows failed to start. A Recent hardware or software change might be the cause. To fix the problem: 

1. Insert your windows installation disc and restart your computer.
2. Choose your langugae settings, and then click next
3. Click "repair your computer."

Status: 0xc000000e
Info: The boot selection failed because a required device is inaccessible.

After trying many different things from many different blogs, the following steps fixed my problem:

Boot off of a Windows 7 disk and go to Repair. Open a command prompt (skip or cancel and errors you get about recovery).

At the command prompt, set your correct Windows 7 partition active (thanks to gregrocker ( on this post:

 SELECT DISK # (for Windows 7 disk)
 select partition # (for Windows 7 partition)

After setting this, I restarted my laptop and then received a slightly different 0xc000000f error.

I then restarted my computer and booted off the Windows 7 disk again and chose repair. Windows automatically repaired my disk successfully and my laptop rebooted properly.

Thanks gregrocker! You are awesome!
