From your description, I would guess that you have the ISO file mounted in the VM and it cannot be found. If you have a properly working Windows 10 VM, close it down and edit the VM settings to unmount the VM, then restart the VM. You should no longer receive the error message. I hope this works for you.

I installed Virtual Box on my Macbook Pro and then installed Win10 from an ISO on a disk. I was then able to install and run WordPerfect. But there's a quirk. When I start VirtualBox, I get a warning that the Windows.iso file is not accessible, and I might have problems. After seeing that warning, I copied the 3.2GB file to the Desktop and ran VB again and got the same warning. After I click to start VB, I get a second similar warning about the missing Windows.iso, although it is on the Desktop. When the Windows.iso CD was in the computer, I didn't get the warnings.
From everything I've read, having the iso file accessible isn't necessary. VirtualBox and Win10 seem to run okay, so what's going on with the "missing" Windows.iso file?
