Choosing system boot mode
System Setup enables you to specify one of the following boot modes for installing your operating system:
● BIOS boot mode is the standard BIOS-level boot interface.
● UEFI boot mode (the default), is an enhanced 64-bit boot interface.
If you have configured your system to boot to UEFI mode, it replaces the system BIOS.
1. From the System Setup Main Menu , click Boot Settings , and select Boot Mode .
2. Select the UEFI 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.
3. 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.
