I accidentally deleted some autorun processes, and now can't restore Windows

I've downloaded a program that detects the autoruns on my system. I deleted some autorun processes from my system and now some good features of Windows have disappeared. More important than all of them right now is that I want to restore my system to factory.

This however gives me the error:

[The boot selection failed because a required device is inaccessible 0xc000000e]

I then tried to use the backup DVDs, but Windows doesn't boot from the CD. When I select "boot from internal CD/DVD" it directs me to Windows.

Boot device selection happens long before autorun services. I suspect you may have removed your restore partition or switched hard drives. If that's the case then you can't perform a restore without boot CD/DVD.
