I was in shocked over the weekend, when I found out that VMware Workstation do not support booting from USB devices, and I did check the BIOS but didn’t find anything . However there’s nothing to stop you booting to CD then using that to boot to USB right? So I did some digging around and found out there is a boot manager utility that allows you to boot from USB devices. It’s called Plop and you could find more information here.
