Hey Ben, sorry for the long delay to response....I had to do a clean slate and start over...this time, I'm able to get RT 7Lite working, but still encountered couple of errors.
Here is the main screen, where RT 7Lite is loading the image...
In the second shot below (this is after I selected the task that I want i.e. Integration, Components, and Bootable ISO), I added the updates...
NOTES: I had decided not to include tweaks, customization and un-attended since I'm just testing out the RT 7Lite.
Next, I added multiple drivers.....I didn't bother with adding Language Packs nor Applications.
Here is the shot of the Features Removal...note, the Default features finally showed up on the right - this never happen before when I was trying to get RT 7 Lite to work right...
Starting the process.....
Now I got this error pop up - this happen when RT 7Lite is integrating the Updates...
Process continues...here you see RT 7Lite integrating the drivers....
Another error pop-up in the process....I do not know what this error related to, maybe you can sled some light on this...
RT 7Lite disabling features and removing components as you can see in this pic...
At last, the process is complete and I'm able to create a bootable ISO image without any problems...
