You have El Capitan, so we need to disable SIP.1. Boot into Local Recovery (Command+R).2. Start Utilities -&gt; Terminal.3. Type csrutil disable in Terminal and press Enter/Return.4. Type csrutil status.5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.Please ignore the i386 MBR error message, but not any others, in the following steps.sudo fdisk -e /dev/disk0psetpid 407flag 4pwyReboot and test.
