so I have a question, I'm using Virtual Box and I have a zipped folder of android8. Can I drag it to virtual box and run it or it needs to be an ISO file

I would advise opening the zip first and seeing what's inside. I don't know which VM you got, but if you share the link maybe I can help. Anyways I don't like virtual box so much, I would advise finding one compatible with VM ware as it's much more screen reader friendly or at least it was back when I used it.

I've tried using the Android 8 VM from Mason's site with VMWare and I keep hearing a beep sound whenever I press a key. I do not know how to solve this, I've E-Mailed Mason about this but he hasn't fully replied to all of my questions. So, for anyone who knows, why am I hearing this sound and how do I fix it?

that beep happens when it is corrupted

I use Mason's system. you find it on masonasons.me
