The message says that virtualization is disabled in the BIOS of your computer. "VT-x is disabled in the BIOS"

Unfortunately the BIOS/UEFI control screens are wildly different between computer makers and even models, so I cannot give you exact instructions, but you must enter your BIOS/UEFI interface at boot, and enable virtualization.
