I also tried repair option from advanced settings and I get a message that the drive is locked. 

Hi,

Please click here: http://dell.to/1u0NJHN ;and follow the steps mentioned to perform factor reset.
You can also try loading BIOS defaults and then reinstall the operating system. Please press F2 on the dell log loading screen and press F10 to load bios defaults.
Let us know if this helped.

Thanks for the reply.  I don't have the option for dell backup and recovery in the boot menu, so those steps wont work for me.  I'm wondering if this is something I can fix with cmd in advanced options.  The 6 partitions are still intact.  Any tips?

System 500mb

Unknown 40mb

Reserved 128mb

Recovery 500mb

Primary 450gb

Recovery 13gb.

I tried the bios reset and no luck.  I have also tried to just install from a win 8 ISO to the primary drive but windows won't let me select it. I'd like to reset this properly to factory settings anyways before I just wipe the drive and attempt a clean windows install.
