BOOTMGR Missing error

Today, I was deploying Windows Server 2008 R2 using an image which I captured from another server using Sysprep and ImageX utilities.

After I deployed the image to my server using the same ImageX utility, and as soon as I started the server BOOM, got a startup error “BOOTMGR MISSING”

To fix this issue, I started my server using a WinPE CD to the Windows Pre Installation Environment, and typed the following command

BCDBOOT C:\Windows 

Restart the server

That fixed the issue
