Choosing system boot mode
The BIOS boot mode (the default), is the standard BIOS-level boot interface.
NOTE: The system also supports the UEFI boot 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 www.dell.com/ossupport.
