good comment, because of the Toshiba retards right now, I can't build my virtual lab. I can't install Hyper-V.I doubt changing the OS would make any difference to the BIOS options. Many laptops typically have a very limited (ie cut-down) BIOS to minimize the risk of the user changing something critical and then expecting the manufacturer to fix it under warranty. Seems to me that Toshiba has removed the ability to enable what you want to do.
Pro or Enterprise windows edition is required.maybe the OS is the problem, I use windows home edition and will install pro, lets see what happens then
