You may want to consider asking if your company will make an exception - you will lose functionality running 7 on this system. Windows 7 doesn't have native support for the USB controller in the system (you'll need to build a custom install media set for the system) and doesn't support the power management features of the Skylake CPU, among other things - not to mention the almost absurd number of updates required by 7 once it is installed.
Thanks for the comment, but my company would rather replace the notebook than make an exception for the OSS. There are security SW that runs on Windows 7.
You're going to have to locate all the drivers from the component manufacturers (Intel, Broadcom, Realtek, etc.) -- Dell doesn't have drivers for this model and Windows 7.
You will also need to build a custom install of Windows 7 including the Intel USB 3 drivers. There's a guide here:
That should get the installation going -- you will be sacrificing some battery runtime due to the lack of support by 7 of Skylake low-power mode, but once 7 is installed you should be set.
