Hi, I have followed the steps as shown in: http://aruljohn.com/info/virtualbox-install-windows/ But at the window screen, it shows "FATAL : No bootable medium found! System Halted" Please help! Thanks.
Assuming you're using VirtualBox, you'll need something for Windows installation. https://royals.ms/forum/threads/discontinuation-of-mac-os-support.85582/ The main post has a link to download a 90-day renewable Windows 7 installation. Head over to that and choose your preferred settings and download it. Then go ahead and continue to steps on the tutorial from "Let's point this virtual machine (VM) to the Windows ISO. We have our ISO at C:ISO/win7.iso In the VirtualBox Manager, while Windows 7 is selected, click on Settings. Select the tab Storage. You should see this:" and so on, but of course, instead of an .iso, you'll be using the .vmdk from the Windows installation. PM me if you need more help!
