Macrium Reflect free doesn't see drives

I created a disk image with Macrium Reflect free which said it was successful. I now need to restore it. I can boot with the CD and find the image, but when it asks me to choose a drive to install it to, it comes up blank. I have 2 drives on my hard drive, but it doesn't see either of them. Any suggestions?

Thanks
