ImageX and appending .wim files VERY WEIRD Discovery!

Question

I have a PC with two hard drives. I used ImageX to image each drive to a .wim file independently.
The first image was of the C:\ drive
The second image was of the D:\ drive.
I then used the following command to append the 2nd hard disk WIM file to the first hard disk WIM file.
C:>Program Files\Windows AIK\Tools\PETools>imagex /append /boot C:\1stdrive C:\Users\MyUserName\Documents\zTestFolder\Prec690_HDisk2Install.wim "Win7"
My thinking was that I could then deploy the image as 1 WIM file. But when I get to the familiar 'Install Now' screen, once I click 'Next', I immediately get the following message.
'The product key entered does not match any of the Windows images available for installation. Enter a different product key.'
So, for fun I decide to try something else.
I use my 'Deploy' UFD and only put in the C_Drive install.wim in the proper default location.
I then successfully install the O/S and it boots into Windows no problem!!!
But, HERE is WHERE IT GETS WEIRD
I do the Diskpart portion so disk 1 can now have an image applied to it.
Then, I apply the HardDisk2.wim file and it is successful...ie it doesn't throw any errors. The command I used was imageX /apply F:\HardDisk2.wim 1 D:\
 But when I reboot, now the system no longer boots into Windows.
Instead it provides error of: No boot device available!

Hello,
The Windows Desktop Perfmon and Diagnostic tools forum is to discuss performance monitor (perfmon), resource monitor (resmon), and task manager, focusing on HOW-TO, Errors/Problems, and usage scenarios.
As the question is off topic here, I am moving it to the
Where is the Forum... forum.
