1. The 100MB partition you can see in Disk Management and also in Macrium.
2. Thinking of it, if you have not unselected the 100MB partition during the imaging, there are chances you might even have an image of it. Double click on the image file and see whether that 100MB partition was imaged by chance. You would see 2 files which you can mount. And if it is there, you only need to create a 100 or even a bit bigger (like 200MB) partition on your disk and then you can restore it into there.
3. But if nothing else, your idea of making a quick install of Win7 and then dump the image of C into that new C partition will work too. That reinstallation will automatically create a new 100MB partition.
