Consider the card  Rhys the Exiled. Are you allowed to play black (and green) cards in your deck with this commander?

Or are you only allowed to play cards that are the same color as the commander's cost? If so, would this then make it impossible to use his ability?

Reflash the card with your OS, which would also fix the boot partition.

Copy the files you want back to your card.
