Choosing The System Boot Mode; Assigning A System And Setup Password - Dell E14S Series Owner's Manual

Choosing the system boot mode

With System Setup, you can 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 and you then 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. Trying to boot the operating system from
the other boot mode causes 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.
