Select the boot mode you want the system to boot into.
CAUTION:
Switching the boot mode may prevent the system from booting if the operating system is not installed in the
same boot mode.

After the system boots in the specified boot mode, proceed to install your operating system from that mode.
NOTE:
Operating systems must be UEFI-compatible to be installed from the UEFI boot mode. DOS and 32-bit operating systems
do not support UEFI and can only be installed from the BIOS boot mode.
