What key do you press to access the one-time boot menu on a Dell EMC PowerEdge server?

To access the one-time boot menu on a Dell EMC PowerEdge server, you press the F12 key. This menu allows you to select the boot device for that particular session without having to change the permanent boot order in the BIOS settings. It is particularly useful when you need to boot from a device that is not typically set as your primary boot option, such as a USB drive or a specific network location for a temporary task, such as system recovery or installation of an operating system.

The F12 key is designed for quick access, making it a practical tool for administrators or technicians who need immediate access to different boot sources during server maintenance or deployment scenarios.
