If the drive is as-shipped from Dell, the operating mode is set to IRST/Intel RAID on.  Unless the Linux distribution supports that (most don't), the installer won't see the drive. You can switch the operating mode to AHCI (raid off) but will either need to configure Windows through safe mode, or reinstall it afterward -- if you change the drive mode without reconfiguring or reinstalling, Windows will no longer boot thereafter.  
I just got this laptop and I am trying to dual boot linux mint. It will not install because it detects bitlocker which is not enabled.. I am hopeing I can get some help here as the linux community is blaming it all on windows. I donl't see a way to add a second drive to this thing and use the boot option window.
