Medion P6624 - Windows 10 Install Guide

Here is a definitive upgrade guide for the Medion P6624 for going from Windows 7 or Windows 8 to Windows 10. This step-by-step guide gets you through all the hoops of the actual Windows 10 upgrade installation, and then fixes driver issues once Windows 10 is installed.

Step 1.
Remove the battery, but keep the power cable in.

Step 2.
Start the Windows 10 upgrade. This image shows the upgrade that starts with the Windows 10 Media Creation Tool. The same information here goes for the Windows Update/GWX update method.

Let it go through the all the inital stages. The Medion P6624 will restart, let it go. This sequence events will happen:

Step3.
When the first stage, Copying Files, has finished and the Upgrading Windows percentage hits 30%, the Medion P6624 will restart.
When it restarts and the BIOS screen is presented, pull out the power cable.

Step 4.

Reconnect the power cable, and power up the computer.

Then the second stage of the installation will kick off (without this plug trick, it will hang).

Step 5.
At the end of the "Installing features and drivers" stage, at around 75%, the Medion P6624 will restart again.
When it restarts and the BIOS screen is presented, pull out the power cable.

Step 6.
Reconnect the power cable, and power up the computer.

The third and final stage will now continue.

Installation of Windows 10 complete.

With Windows 10 installed, there are two more things to do.

1. Replace the default USB3 driver, it causes a hang on restart. The default Windows 10 driver has the same issues as the Windows 8 driver on the Medion P6624. It's fine from a cold start, but system restarts cause lockups.
2. Replace the default nVidia driver, it crashes Direct X on the Medion P6624. The default 353.62 nVidia Windows 10 driver has the same issues as the Windows 8 driver on the Medion P6624 - DirectX applications hang instantly.

Step 7.
Install this USB3 Reneasas driver from Intel.
Install the Nvidia Geforce 344.65 drivers from NVidia.

Done! Enjoy.

not that sort of N-Joi

Conclusions.
With these installed, your Medion P6624 running Windows 10 should restart without hanging, and the Geforce GT425M in it should run DirectX applications without crashing.

I have to thank user DS_POS from this thread (warning, it's in German) for making the logical extension of my previous findings with Windows 8. I think the BIOS in the Medion P6624 needs work. My very strong suspicion is that it has something to do with the RESTART state, and the USB3 controller. I saw someone say they could Disable Legacy USB in the BIOS and get the same result, but when I did that, I couldn't boot at all.
As for the NVidia Geforce GT425M problem, I'm at a loss to explain that. I think that is simply a driver issue with NVidia, but using the very latest NVidia drivers still does not work so stick with 344.65 and IGNORE all advice to upgrade for now.

Happy upgrading!
