Hey Guys,
Thank you for your replies. The issues I stated here was because of the UEFI being enabled. UEFI Didn’t like the fixed partition sizes. As the FOG Developers stated, changing the images to “Resize partition” fixed the issue for UEFI Machines. Using this method, I was able to make an image on a 500gb HDD and deploy it to a 256 SSD without issue.
In regards to the “not booting after successful restore from UEFI”, that issue was limited to older Dell modals that have never booted to UEFI before. Once i selected the boot device the computer booted fine every time after that. They booted even after subsequent re-images.
I am currently running version 1.5. RCx.

Thanks for all the help.
