Install Windows 10 and immediately upgrade to Windows 11
I thought I reinstall my entire Windows / Linux Setup and for Windows I upgrade immediately from Windows 10 to Windows 11. It's free, so why not.
Unfortunately, even after hours of installing all the updates, Windows didn't offer me the upgrade to Windows 11.
Finally I used the "Netinstaller" from Microsoft and did it this way. https://www.microsoft.com/en-us/software-download/windows11
