appleshark replied to Rammjet's topic in Tutorials (The Genius Bar)Hi, i am trying to make my disk or partition active so OSX will boot. I typed in "diskutil list" and it returned me with "/dev/disk0, /dev/disk1, /dev/disk2, etc." how is it that yours has a "r" in front of "disk." Also when i typed the sudo command it also said "command not found." I tried putting the "r" in where you had it, but it didn't make a difference.
