Hard to say without actually having the disk :-).
I have never seem a one time OEM install disk so am reluctant to offer advice. In my experience, CD/DVDs that come with OEM installs are normally reusable. Perhaps your hardware vendor could tell you whether it is possible to use your CD/DVD as ISO media for the purposes of this task?
What you need is a disk with the install.wim file on it, this ought to be in the "Sources" sub-folder.
