If for some reason your attempt to boot into a new disk fails with error 0xc000000e, the boot selection failed because a required device is inaccessible. Try the following:
- Boot into the OS cd/iso
- Chose Repair
- Command Prompt
- Run the following:
- bootrec /fixmbr
- bootrec /fixboot
- bootrec /rebuildbcd
Reboot and you should be good.
