If you use the Partition tab in Disk Utility, which is visible when you select the disk device in the table, then select "1 partition" in layout, you can erase the entire disk and repartition it with one partition in one step. Make sure to press Options and make sure that "GUID partition table" is selected (it should already be). Then press apply, press partition, wait a few moments and it's done.
You will not be able to do this with the recovery partition. You will have to create USB install media or, if your Mac was purchased with Mavericks on it, use Internet Recovery. You can't partition a disk while you are booted from recovery on that disk, of course. -- You received this message because you are subscribed to the Google Groups "MacVisionaries" group.
