Add a bootable USB key to ProxMox

Create a guest VM in Proxmox using a bootable USB key

Having messed with mounting a drive in linux and permissions...I realized this is easier than I thought.

I had created a bootable USB key with Windows 11 using RUFUS.  

Here's how you mount it in the server

Plug in your key into your ProxMax Server

Click on the "HARDWARE" section in your Windows guest summary and click on ADD

Select USB DEVICE

Select "Use USB port" -> Passthrough a full port -> then select your device

Then under summary, goto OPTIONS - >BOOT ORDER

Set the USB key to boot first and press OK (you may not even need to change the boot order, might be better to leave lower.  If new guest, then there's no data on HD anyway so it will likely default ot it.)

Start your virtual machine and you should be good to go
