have write this before:
I have had the same issue with win 10 14.939.10 64x Pro
I tested some ways. Crasched sometimes at 16% installation or 33 % by flickering
Shutdown Computer dont help Black Screen and System hang on...
i have found a way for me to solve it, but the Driver dont fixed other issues that i have sience Win 10
Try this, donwlaod Amd Clean UP Utility (its alway in the install Folder)
Execute it, restart.
in System Manager / Hardware Manager show that the Videocard is not installed (yellow) if installed Automaticly try Uninstall with Right klick and uninstall with Software Checkbox
Win 10 must up to date, but Videocard not installed.
Than Downlaod / extrakt Crimson 18.104.22.168 install it normal way with all but Uncheck the "automaticly install drivers"
after installing Restart than Downlaod /extract 22.214.171.124 install it as Upgrade (not uninsatll 126.96.36.199)
make sure that "automatic install drivers" is unchecked (i make that cuz some drivers give me bad fps)
Now no Crash at install or Black Screen at Starting Windows for me.
But have not Full Screen sience Windows 10 build 10240 on Dirt Rally with my VGA monitor on Laptop , CSGO work only in Windowed FS mode with my Vga Monitor but only 1680x1050 (win7 give me Full HD 1920...)
If u have a Running louder Fan or 0.80V power in Desktop (if the Gpu dont turned off in 2D) close the Rapter and Plays Tv App in Windwos Task (need Configured in Catalyst/crimson that Energy is on loweer mode for this app but for Recording it needs Balanced mode i think)
By a Restore Cuz the "update" was an upgrade from Microsoft
have u Disable Signed Drivers (not in cmd) in Safe Mode? have a look to Disable Windwos automatic downlaod and installing Drivers by Windows Update?
I have make a Systemrestore, and become unstable System with Hang on by installing 16.7.3
After uninstalling in Safe mode, i try to disable Signed Driver, in cmd it dont work with new System w10(Premissions)
i disabled service and have a look on gpedit.msc ...try to disable that WIndwos Update installing self Driver Updates for Devices (u must know what u have to install...)
Disable in Hardware Options the "Validiate" and u can choose the driver self and than installing the Software (this must i do for new intel mGpu drivers)
THis helped me after System Restore W10 14939_10
But i must go about 188.8.131.52 non WHQL (not install First the WHQL 184.108.40.206 this give me Error and problemms with Microsoft Signed Drivers...) and over it i Upgrade to 220.127.116.11 and Uncheck Automatic Installed drivers.
i have the same problem with my laptop Lenovo G510 (R7 m265) which is the same as your graphic card i had to reinstall the OS multiple times (win10) trying to install the driver but i still don't find a way to do it . it always freezes when installing the amd driver settings at 55% i can't even move the mouse so i have to restart the laptop and when i do i get a black screen which lead me to reinstall the OS , i have to point out that happened to me after the windows 10 anniversary update.
I have the same problem. If I install any other windows, its ok, buth windows 10 anyversiry edition is broken. Cant install any AMD drivers, PC will hang, restart wont hepl, only reinstall of OS
