Win7/64-bit to Win10/64-bit screen locking up while attempting to boot

So I wish I could post the image without having to host it via a URL, but its quite simple, I attempted an install of Win10 when I first got the go-ahead several weeks ago, it went through the entire install (which took an eternity) and then decided it was incompatible as windows updater encountered errors, it reverted back to 7. Last week I tried again and the pre-install launcher came up with an obscure windows update error, which fixed after downloading and installing the auto-tool for windows updater, but then came up with yet another different error with winupdate. I restarted, Rand the tool again, and although the window still showed a red X and the same second error , it allowed me to click "retry" which then just force launched the windows 10 migration. I figured might as well, didn't prompt me with any warnings about the potential error so anyways long sorry short after going ahead, it now freezes on the new logo immediately when it tries to boot the OS, after a couple turns of the progress wheel. Don't know where to go from here and it doesn't seem to be reading any peripherals. Have disconnected and reconnected power and had to force shut down nearly half a dozen times.

If you try to load Windows 2-3 times, eventually you will see the troubleshooting screen. There you may select a startup repair, but if there are some drivers causing incompatibilities this won't be enough. Next step is to select Advanced startup options and try booting into Safe Mode. I recommend to select Safe Mode with networking, so you also have internet access and try to download drivers or other tools. If you can at least boot in Safe Mode, then you can send us a system report (see the troubleshooting section for details) and we will be able to help you. Or try describing some symptoms and we can understand.

So it is saying the operation completed successfully (in the cmd prompt) when I try to launch safe mode with network. But it then just gives me a fresh script line and a blinking cursor and no changes in the UI.

Try updating some drivers while in Safe Mode. Press Win+R to launch a Run prompt and type msconfig. This will run System Configuration where you can go at the Services tab. Then check the box to hide all Microsoft services. Some of the remaining services can be unchecked and disabled (mostly application update services) so they don't load at startup. Some of them might cause the problems. Also click on the Startup tab and then Open Task Manager to see the startup applications. Again disable any non-important application (like Skype, QTtask and others) to speedup computer and also avoid loading the one causing the problems. Restart, let Windows start normally and see if you still have any issues. If you do, enter Safe Mode again and run the forum utility to generate the report (see BSOD section).
