Chapter 3. Troubleshooting
When do I need to change the boot mode?
The default boot mode for your computer is
UEFI
mode. If you need to install a legacy operating
system, such as Windows, Linux or Dos, etc. (that is, any operating system before Windows 8)
on your computer, you must change the boot mode to
Legacy Support
. The legacy operating
system, such as Windows, Linux or Dos, etc. cannot be installed if you don't change the boot
mode.
