Looking to create a bootable USB.  Want to be able to do diagnostic tests as well as add third party applications.


Does anyone have good set of instructions to do this.


I have looked around on the net and have not found anything for the diagnostic and third party apps.


Thanks and I look forward to your reply.

    Thanks for the update Eric.


    To expand on the issue, let me ask this.


    Should I be creating bootable external drive with two partitions.  One for Mac OS X and the other for 3rd paety software,


    Or should I only have one parttion since the drive is intended to be bootable.


    In addition what size external drive is appropirate.


    Thanks and I look forward to your reply.

    You will probably want something at least 32 gig.  Personally,

    I have a high speed SD card with a base install and all the diagnostic

    and repair goodies on it.


    Creating is simple, create single partition (make sure in options you set

    GUID scheme otherwise it won't boot).  Installing OSX can either be done

    via the App Store installer or you can boot to the Recovery HD and install

    OSX that way.  Going the Recovery HD route does not install all the iLife

    stuff, iPhoto etc., so will use less space.  You can then boot the newly

    created volume and install your repair tools.
