I am trying to create a new partition so I can install Windows through Boot Camp. I boot into recovery mode using my Recovery Assistant USB and no matter what I do, when I try to resize my drive and create a new partition, I get this error. What am I doing wrong?
Have you tried repartitioning with Boot Camp (just go through the Boot Camp process normally)? You shouldn't have to repartition manually in the first place.
Use Boot commands for mac os x
You should install OS X on an external hard drive and wipe your internal hard drive. Hopefully, if there's nothing on the internal drive, the OS won't bother mounting it.
