    Will the same process work for a Win 8 PC as well?

    • Hi Peter,

      Yes this should work on any device, though there is also an alternative .iso method.

      It’s been reported in the last day or 2 that the Preview install has worked on some installs of Windows without changing language packs around. This is due to an update released by Microsoft to address the language issue.

      So jump to the final step first and see if it installs as is. If so, you can skip the rest of the process.
