To install Windows cleanly on your Rok Box (if you cannot recover from your Windows Recovery Image), please do the following:
Please go here to get the Windows Media Creation tool for your Windows version:
Windows 10: https://go.microsoft.com/fwlink/?LinkId=691209
Then, run this tool, and when prompted, choose the default options of the tool:
Now, we will install the installation media onto the USB thumb drive we plugged into the PC:
Windows will now create a bootable Windows installation USB:
With this USB stick created, reboot your PC and boot from the USB thumb drive as such:
Hold down the F11 key on your keyboard if you have a Rok Box MC or CR series Rok Box.
Hold down F7 if you have a Rok Box MC Mobile laptop.
You will be prompted to choose which disk from which you'd like to boot.
Select the USB drive inserted into your Rok Box as your boot option.
The Windows installer will load.
You should then be prompted to install Windows to the OS drive in your system.
You may choose the option, "I don't have a product key", when prompted. This is because your Windows installation key was registered to an online service when your PC was built.
Next, choose "Custom" as your installation type:
You'll be presented with an option to choose the drive onto which you will install Windows -- this will typically be the drive listed as "drive 0":
You may see other drives listed -- their names will show next to them (Audio, Samples, etc.). DO NOT choose to install Windows onto one of these drives. This will result in loss of your data on your drives.
Hit "Next". Windows will begin the installation process.
This will completely reinstall Windows, and so any files on your primary drive will be lost.
Windows will finish the process, and then reboot itself:
Once complete, Windows will load as a completely-new, non-tweaked version of Windows.
If you wish, you may contact PCAudioLabs Support for help with tweaking your Windows installation.
