default.

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 congured 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 specied 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.
NOTE: For the latest information about supported operating systems, go to Dell.com/ossupport.
