Hi Loner T,

To rebuild the MBR, do I proceed from within Terminal, and basically copy and paste your instructions one line at a time?

Thanks!

Jordan

Hi Loner T,

I apologize. I’m a brain donor and can’t figure out where to start in order to follow your instructions. How do I find the MBR and what Application would I use?

Without making any adjustments to my present situation, the answers to your Test Questions numbers 1 through 4 are YES to each. However when I Restart after selecting Bootcamp, the resulting prompt is “No bootable device - insert boot disk and press any key.” Then again to proceed I have to force a Restart, hold down the Option key and choose Retina or Recovery-10-9. Could Recovery-10-9 correct the problem?

Thanks!

Perfect. I jumped into Terminal and entered the command for the following response:

It appears that I don’t have a gdisk? The screen captures below show BOOTCAMP and RETINA as well as the folders within BOOTCAMP...

Ideas?

Thanks!

Nice! I’ve got the command script this far. What Recovery/transformation command should I enter?

Reboot.

I held down the Option key upon reboot and Bootcamp presented me with the option of starting in OS X or Windows! When I selected Windows, it went through the normal sequence of launching Windows, and tried to install and update device driver software. Then followed with a message that the device driver software was not successfully installed. I had no control of the cursor, mouse or any keys.

To make sure Windows was still OK, I launched Windows 7 through Parallels / OS X, and it opened up fine.

I'll try restarting Windows from the Startup Disk:
