If you have a Windows Deployment Service (WDS for short) hosted by Windows Server 2012 R2 (w or w/o update), never try to add a boot file from Windows Server 2012 R2 with Update (MSDN CD) or Windows 8.1 with Update (MSDN CD). If you do so, all capture image, no matter which version of boot file is based on, or it’s created by this server or others, just cannot work. After the loading finished, you will get an error in winload.exe with the status code 0xc000000f.
If you have been in this jam, you have to restore the whole boot folder from the backup before you attach the new version boot files. Don’t forget to stop the WDS before you replace the folder. Delete the new boot file only won’t work.
Update: There is another way to fix the broken capture image file directly. But you have to do that for every capture file. http://social.technet.microsoft.com/Forums/windowsserver/en-US/a164b948-1778-42bd-8d77-9cef1ca70866/image-capture-boot-image-fails-with-0xc000000f?forum=winserversetup
