Is this error resolvable? If yes, how.

Thank you for your intervention.

The issue is blocksize. The new macs have a 4k physical block size. Please create a winclone image using wim (file) based imaging and then it should restore fine. You set this in preferences.

I’m having a similar issue. When using the “Quick Install Windows” feature, it gets to about 90% complete then errors out with “An error occurred when trying to determine the Windows mount point. Please check the log for more information”. The logs show this information.

I am using a Windows 11 ISO from the Microsoft download site.

What version of macOS on what hardware?
