BOOTCAMP HELP
I recently just tried to set up a windows partition using boot camp but I messed up the installation and only just managed to get back to my mac volume which thankfully had no files erased from it.
However I had a new volume that appeared called disk0s1 which must have been created when i did the installation wrong...
when i go to boot camp again i get the message
"The startup disk must be formatted as a single Mac OS Extended (Journaled) volume or already partitioned by Boot Camp Assistant for installing Windows."
i realise that this message must be due to the other volume i have so i want to know HOW TO DELETE THE VOLUME????
so i can redo the boot camp... i have tried using disk utility with no success
