Have a challenge.
I have recently added an SSD drive to my system and cloned the original main drive. As I make use of bootcamp deleted the bootcamp partition from the original drive and plan to use it just as a data disk (it already has my data on it).
Disk A:
The trouble is I am now being presented with 3 disk options on start-up as both the SSD and the original disk OS X instances are showing (as well as the Windows).
How do I stop the original disk being bootable ?
I have taken a look at fdisk and diskutil which both show that the original disk has the bootable flag set - but I have no idea how to remove the setting.
Any help greatly appreciated.
