Hi,
type services.msc into the startmenu search and launch the tool. Search the Superfetch entry and make a double click on it. Now change the start type to "automatic" and click on start. The service now starts and you should be able to use ReadyBoost.
Btw, you should never disbale Superfetch, it slows down your PC!
