[Test your Multipass in a Virtual Machine!]

Wow !! Thanks so much ...you have no Idea how frustrating it is to always go to your neighbours house to test it :)....Now the cream would be to include XP somehow, so I can try out kon-boot and ophrack...but I guess thats hardly possible, right ?

NP. Now I'm just looking for an explanation as to why the drive has to be physically removed from the computer rather just disconnected and reconnected within VMware. It shocks me that they don't have USB booting within their BIOS natively since it is a virtual machine. The neighbor's 5 year old Dell supported USB booting, I don't see why they can't too.

It's not possible to install VMware inside another VM. It sounds like Fusion recognizes some configuration options differently than Workstation and Player for Windows, like how flash drives are auto-connected. Try to connect the flash drive manually, although I'm not sure how to do this in Fusion.

I had the same problem with VMWare Fusion on the Mac. I figured out a solution.

Make sure that your settings are set to auto connect USB devices. Physically remove the drive from your mac. Start the virtual machine. Select USB, then immediately after, plug your USB drive back in to the computer. An error should come up. Hit enter to return to the menu. Select USB again, and this time, it should boot into GRUB. It's worked for me.
