Are you using the latest Parallels Desktop 5 build 9370?
Does your Windows 7 work correctly without problem when you boot the Mac to the Boot Camp partition? If it boots ok that way then it should boot ok in Parallels Desktop. If the Mac does not boot ok to the Boot Camp partition then you should try to fix that first before trying to boot the Boot Camp partition in Parallels Desktop.
Have you ever successfully booted the Windows 7 partition in Parallels Desktop? Did you install Parallels Tools yet? If so, then try removing Parallels Tools when you boot your Mac using the Boot Camp partition.
How is your disk partitioned? Use the following commands in the Mac OS X Terminal.app to find out:
Code:
diskutil list
sudo gpt -r show -l disk0
sudo fdisk /dev/rdisk0
