Downgrade from Windows 8 to 7

I have a customer who brought in a Lenovo x240 that came pre installed with Windows 8. She wants Windows 7 installed on it and I'm having trouble even getting started. I read there can be some major problems with the partition tables being in the wrong format. I want to make a image of the drive with Windows 8 on it and I can't even get Clonezilla to boot.

Any help would be greatly appreciated.
