What key do you press to access the one-time boot menu during system restart?

Pressing F12 during a system restart accesses the one-time boot menu on Dell systems. This menu allows users to select the device they want to boot from, such as the hard drive, USB drive, or CD/DVD drive, without needing to change the BIOS settings permanently.

This feature is particularly useful for troubleshooting, running diagnostics, or booting from recovery media. Since many users frequently change their boot device based on temporary needs—like installing an operating system or running a live environment from a USB stick—having quick access to this menu streamlines the process significantly.

The other keys listed do not serve this purpose; for example, F10 is often used for system setup or BIOS configuration rather than for choosing a one-time boot option.
