After installing Windows 10 on the Dell Latitude e6410, you may have a blank screen. If you plug in a monitor, you should be able to finish the setup and login. Follow the instructions below, and you should be able to get it working. I am sure these could be used or modified for other laptops with Intel Graphics.
Download the Intel graphics drivers from Dell, extract it with 7zip or something, edit the file Graphics\boa64.inf:
find the section [Manufacturer] and change the following:
%Intel% = IntelGfx, NTamd64.5.1, NTamd64.6.0, NTamd64.6.2
; no install on XP
; no install on Win8
%Intel% = IntelGfx, NTamd64
Go to Settings, Update & Security, Recovery, click “Restart Now” under Advanced startup;
Choose Troubleshoot, Advanced Options, Startup Settings, click “Restart”;
Hit “7” (or whatever number says “Disable driver signature enforcement”;
Go to Device Manager (can be found in Control Panel), Expand “Display adapters” and right click on “Intel(R) HD Graphics” (or whatever it’s calling your video card), and click “Update Driver Software”;
Click “Browse my computer for driver software”, click “Let me pick from a list of drivers on my computer”;
Click “Have Disk” and browse to (where ever you extracted the drivers from Dell)\Graphics ;
Pick Intel(R) HD Graphics and click “Next”
This should install the drivers and make your laptop display work. You may have to disable automatic driver updates if you have trouble in the future. You can find instructions on how to do that by “Google-ing” it.
Hope you find this helpful, as it took me a long time to figure it out. Thanks to all others troubleshooting this, as I would not have figured it out on my own!
