Windows 7 drive hosed by XFDisk?

I tried to test a Broadcom network diag CD that I created from the iso image off there website.
http://www.broadcom.com/support/ethernet_nic/netxtreme_desktop.php all the way at the bottom.
Some how it installed the freedos on the system drive using the xfdisk and now I can't boot to windows.
When I try safemode it hangs on classpnp.sys
when I try to install from the windows 7 CD and do a custom install or a normal install it says the partition is of an unrecognized type.
I read somewhere that I might have to change the disk from dynamic to basic. I never remember changing the disk to dynamic.
I tried the last known good config
I tried the startup repair and that just fails.

Is there a utility I can run to get the drive back?

so its put a invalid boot disk so you may not be able to rectify it unless you can use a disk tool to renmove the offending boot partition with something like pxe or acronis

Free Tool: Port Scanner

Check which ports are open to the outside world. Helps make sure that your firewall rules are working as intended.

as you mentioned the windows setup cannot read the boot partition so you will have three partitions imho the freedos one, the dell diag and the windows one
