Choosing the system boot mode

System Setup enables you to specify the boot mode for installing your operating system:

•BIOS boot mode (the default) is the standard BIOS-level boot interface.

•UEFI boot mode is an enhanced 64-bit boot interface based on Unified Extensible Firmware Interface (UEFI) specifications that overlays the system BIOS.

You must select the boot mode in the Boot Mode field of the Boot Settings screen of System Setup. Once you specify the boot mode, the system boots in the specified boot mode, proceed to install your operating system from that mode. Thereafter, you must boot the system in the same boot mode (BIOS or UEFI) to access the installed operating system.

CAUTION: Trying to boot the operating system from the other boot mode will cause the system to halt at startup.

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 on supported operating systems, go to dell.com/ossupport.

Assigning a system and/or setup password

Prerequisites

NOTE: The password jumper enables or disables the System Password and Setup Password features. For more information on the password jumper settings, see “System board jumper settings”.

You can assign a new System Password and/or Setup Password or change an existing System Password and/or Setup Password only when the password jumper setting is enabled and Password Status is Unlocked. If the Password Status is Locked, you cannot change the System Password and/or Setup Password.

If the password jumper setting is disabled, the existing System Password and Setup Password is deleted and you need not provide the system password to boot the system.
