Jul 30, 2015 1:54 PM in response to MrShady5721by Loner T,Ah!. You are on ELC (Beta). This may not work. You can try
sudo fdisk /dev/rdisk0
instead of
sudo fdisk /dev/disk0
You may have to erase your internal disk and start over.

Mar 21, 2016 11:40 AM in response to jrichardsonn9by Loner T,If you are on El Capitan, you need to disable System Integrity Protection - About System Integrity Protection on your Mac - Apple Support .
1. Boot into Local Recovery (Command+R).
2. Start Utilities -> 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.
Now retry you Fdisk commands.
