Run Boot Camp Assistant again.
Then try Disk Utility and delete the Windows partition, then drag the divider of the Mac OS X partition to the bottom.
what exactly should be done there is no "delete" should i erase or what and when you say drag the driver down what is meant to be done
The delete button is the one with the "-" (minus).
i must be looking at the wrong thing because there is no minus sign a plus one and a ton of erase options but no minus disk utility right?
