Windows 7 not seeing SATA drives

I was trying to install Windows 7 on a system, and it wouldn't see the SATA drive. All evidence pointed to the drivers being correct and not needed; but the drive wouldn't appear.

Finally I determined that because the drive had a dynamic disk on it, Windows 7 setup wouldn't even acknowledge that it existed. I booted Ubuntu and wiped the partition table, and then it worked fine.
