Hi Blackcells:
Finally, after about 25 more minutes, OS X El Capitan should be successfully installed on the target drive. Boot into El Capitan via the USB Device. After the second reboot, boot from the USB device once again, but this time, select Boot OS X from El Capitan, and select verbose mode. Press Enter and cross your fingers again. If all goes well. I suggest using an SSD as this will improve boot times on the Mac Pro once you are done. Once the restore is done you can reboot the Mac Pro and hold down the Option key until you get the boot chooser screen. Pick the new copy of El Capitan you just restored and start up from it. That is all there is to it!
I assume that you have gone into 'System Preferences' > 'Startup Disk' and set it to your original drive in data doubler.
Try removing your new SSD and putting it in an external caseOWC external case or using a USB to SATA adapter USB to SATA adapter and connect it to your MBP via USB.
Open Disk Utility>Erase and format the SSD to Mac OS Extended (Journaled) and a GUID partition.
Install El Capitan Dmg
Then use a third party application such as Carbon Copy Cloner Carbon Copy Cloner (Not free, but worth the price) or Super Duper to copy all data from the internal HDD as well as the recovery partition.
The clone will be a exact copy of your hard drive and it will be bootable.
Boot the MBP with the OPTION key and select the new SSD.
Install El Capitan App
If it boots the MBP, perform the physical swap of drives.
