copying boot drive problems

Seems a lot of people like Macrium Reflect so I tried that. I'm trying to replace a 128 GB SATA II SSD with a 256 GB SATA III SSD. Tried the free version to clone the boot drive and it recognized both SSDs and cloned the boot drive to the new one. The original boot drive was 83.4 GB and the cloned one 77.5 GB. The new one wouldn't boot, so  I downloaded Macrium Reflect Pro and exact same result. I'm using Windows 7 64 bit.

I'm putting the new boot drive into the same SATA port as the old to eliminate that as the problem even though it shouldn't make any difference. I believe the computer looks at all the SATA ports for a boot drive then boots to that, and I can put the current boot drive into any SATA port and it will boot.

Windows 7 backup and restore didn't work. Any suggestions besides reloading all the stuff onto the new dirve.

Thanks
