Choosing The System Boot Mode; Entering System Setup; Responding To Error Messages; Using The System Setup Navigation Keys - Dell EMC PowerEdge R620 Owner's Manual

Choosing the system boot mode

System Setup enables you to specify one of the following boot modes for installing your operating system:
• BIOS boot mode (the default) is the standard BIOS-level boot interface.
• Unified Extensible Firmware Interface (UEFI) (the default) boot mode 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 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.
• For the latest information about supported operating systems, go to Dell.com/ossupport.

Entering System Setup

1 Turn on, or restart your system.
2 Press F2 immediately after you see the following message:
F2 = System Setup
If your operating system begins to load before you press F2, wait for the system to finish booting, and then restart your system and try
again.

Responding to error messages

If an error message is displayed while the system is booting, make a note of the message. For more information, see System Error
Messages.
NOTE: After installing a memory upgrade, it is normal for your system to display a message the first time you start your system.
