I broke windows on my Odyssey X86J4105

I read up on moving my windows installation to another drive on my Odyssey X86J4105. I installed a M.2 NVMe drive and followed the instructions to move it from the mmc to the new drive. I had some problems about half way through the process and ended up not being able to boot windows.
I tried to do a fresh install with the Windows Media tools, but it will not accept the Key I got with my order. Is there a Windows 10 disk image I can download?

Of course, you can download the image from Microsoft’s official website.

Start the system to the installation media for the installed version of Windows.

On the Install Windows screen, select Next > Repair your computer.

On the Choose an option screen, select Troubleshoot.

On the Advanced options screen, select Startup Repair.

After Startup Repair, select Shutdown, then turn on your PC to see if Windows can boot properly.

I tried to install Ubuntu 20.04 on my ODYSSEY-X86J4105 (with Windows 10 pre-loaded). But, half way through (write after setting the time zoon), my installation crashed. Now, I cannot boot Windows also. Is there any way I access windows 10 again?
