Thanks Bert. I tried disk management, could not enlarge the C drive as it did have the recovery partition after it, before the unallocated space.
So, I went back to cloning. Thanks to you Bert, I had the old hard drive still in place, just had to plug it back in. Macrium offers the option to change the partitions before you start the clone. I ran the cloning again, this time enlarging the new C partition to capture the unallocated space. Voila!
