I have twice attempted to install BT4 on my hard drive so I can dual boot with Windows 7,

After booting to the Live CD and clicking the Install.sh, I have used the manual partition option. I partitioned my drive in two partitions with my Windows installation being the 250GB partition and the Back|Track being 200GB.

All goes well until I try to install on the newly created partition and I get an error that says "No root file system found" and it won't let me continue unless I select my Windows partition, at which point it formats the entire drive.

I have done this twice and I get the same results. Any assistance would be greatly appreciated. Thanks for your time and input.
