Please go to this link (not the catalog)

https://www.microsoft.com/en-us/software-download/windowsinsiderpreviewiso

And download this ISO:

Mount the ISO, then open the file and click Setup.

    Why is it deleting my posts on how to get the iso download and instructions to mount it to run setup?

    Hi,

    Going to ask, is your PC fully Windows 11 compatible?

    Run this: https://aka.ms/GetPCHealthCheckApp

    If it is, then at this point I would use the Media

    Creation Tool and do a total clean install and

    then rejoin Insiders. Backup important files,

    documents, photos, etc. first.

    This could also be part of your problem,

    Optional Diagnostics has to be On.
