When I click on the green arrow start, the Fatal error shows up.

Can you guys let me know what I can do to install windows on my mac? Im trying to run only 1 software that is only compatible Windows.

It seems like you have been trying to mount random host files as virtual media, and generally made a big mess.

If I was you I would scrap and delete everything I'd done so far, and start again. Don't thrash. When mounting optical media the correct file type is the ISO you downloaded from the Microsoft site. Choose the correct guest OS template (Win10, or Win8.1 if using <VBox 4.3.28) when creating the VM. And read the first few chapters of the VBox user manual, which covers first steps in creating a VM.

HI thanks! I will read the manual, uninstall and try it again. Hopefully its gonna work this time!
