Enable or Disable UEFI Secure Boot for a Virtual Machine
UEFI Secure Boot is a security standard that helps ensure that your PC boots using only software that is
trusted by the PC manufacturer. For certain virtual machine hardware versions and operating systems,
you can enable secure boot just as you can for a physical machine.
In an operating system that supports UEFI secure boot, each piece of boot software is signed, including
the bootloader, the operating system kernel, and operating system drivers. The virtual machine's default
configuration includes several code signing certificates.
