Hope you were able to fix your Home Assistant. I just came to quickly recommend a way to easily backup your installation. https://github.com/sabeechen/hassio-google-drive-backup

I recommend Rufus for a hassle-free W11 install. Download the official iso from the Microsoft website and use Rufus to put it on a USB. Rufus has options to bypass the W11 hardware requirements and to bypass the need for Internet while installing W11. This will also disable the need to login to a Microsoft account.

There’s workarounds by going into CMD during the Windows install but Rufus makes it a lot easier.
