Hi Embion,
Thanks for coming back to us on this one. Just to confirm that Tudor's response was correct. All of VM's boxes run Linux software so therefore when going through the verification steps, it will show as Linux. If you wish to sign in then you will need to allow it when prompted.
Just as a side note, the bit on Tudor's post about 'There are 10 types of people...' - this is part of their signature and not in response to your question so no need to look at this 🙂
If you have any further questions or concerns, pop back and let us know.
Thanks,
