So this past week, I bought this new DVD from eBay. It was a MAC OS X Yosemite DVD, and I was hoping I could try to install this DVD into VirtualBox and run the OS in there, under my Windows 8.1 PC. I've had no luck so far: I've tried to convert the DVD to an ISO, also tried converting the DVD into a so-called bootable USB drive, still nothing happened. I even tried to install using VMWare, with the same results, nothing. If anyone has any suggestions on what I should do, or have any advice, please let me know. It would be greatly appreciated. Thanks!
