Problem: Windows 10 black screen with no cursor after initial installation.
Specs: ASRock Z77 Pro Motherboard, i5-3570, nvidea GTX 770
Status: SOLVED!
Ok, I spent awhile reading this topic. I'll give you a breakdown of my issues and how I fixed them. This particular fix should be applicable to you if you have a graphics card (discreet) and onboard graphics.
I installed W10 and everything went well -- until the initial log in. All my files and information was there, but the resolution was god awful! I couldn't see a thing. I updated my drivers for my gfx card before I installed, so I figured I should be good to go. Well, I changed to 1080p and about 5 seconds later, my computer gave me the black screen of death. I restarted, got the Windows Icon and loading circle, then it went back to black screen. I tried restarting, no go. I tried using an HDMI cable plugged into my graphics, no go. I tried HDMI into my motherboard, no go. What I had to do was uncheck multi-monitor graphics in my BIOS. Access your BIOS by hitting the appropriate "F" key (mine was F2). To find my settings, I had to navigate to advanced settings and go under the "North Bridge" options on my motherboard. Like I said, my motherboard is a "gaming" motherboard, so yours probably won't be as involved.
After I did this, my issue was not fixed. After I changed the setting, saved my bios, and restarted, it only allowed Windows to boot into Recovery mode. At this point, I realized that it was definitely something messed up with my graphics. If you don't want to lose any data on your hard drive, you can roll back to a previous build. This "build" that it is referring to is actually your last version of Windows, so don't worry -- it'll work. I, though, did not want to go back to W7. In my case, I have my OS installed on an SSD with various smaller programs (it's only 110gb). I elected to choose the option "reset this PC." What this will do is install Windows 10 CLEAN (MEANING YOUR C:// DRIVE WILL BE WIPED!!!! but no other drives). Since all my data and games are on a different drive, I didn't care much.
After I installed W10, I reinstalled my programs/launchers (steam, battle net, origin, Spotify, chrome, etc) and everything is working swimmingly. I'm typing this on W10 as we speak. All my data and games are still installed, but my SSD was wiped. The launchers all point to my games still and it all works fine.
So, to recap, it is definitely an issue with conflicting onboard and discreet graphics. After some more looking, I noticed that there was a recurring driver error when I tried doing the "unclean" install. After the clean install, Windows installed the correct drivers and everything works fine. So, this may not be an answer you want, but its the one I can give!
If you're having troubles getting to the recovery screen, try only using onboard graphics in your BIOS. While you set up -- that may let it POST into recovery. Unfortunately, for us "Day 1'ers," we have to jerry rig our..well..rigs at times.
Cheers!
