RZFeeser_Dell_E6420_Driver_Installation_OrderI recently rebuilt a friend’s Dell Latitude E6420. After a fresh Windows 7 install, I installed the relevant drivers in a haphazard manner, and found that many of the devices were still failing to be recognized in the Windows Device Manager. After a quick Googling, I found that Dell has a specific order that must be observed when the drivers are installed onto the laptop after a fresh Windows install.

Just in case anyone else is looking for this information, I thought I’d repost it. Remember that your laptop may not require all of the following drivers. For example, if you don’t have a Nvidia® NVS 4200M, then don’t install the driver. If you just came off of a fresh Windows install, before you install a single driver, create a restore point (Windows 7 > Start > Search > “Create a Restore Point”). If you do install an erroneous driver, or install a driver out of order, you can always restore back to a fresh state.

The link to the official Dell E6420 driver install page is here: Dell E6420 driver installation order.

If the Dell E6420 page ever gets taken down, the driver order is as follows:
