Which key should be pressed multiple times to access the Boot menu during startup?

To access the Boot menu during startup on a Dell device, pressing F12 multiple times is the correct approach. This key is specifically designated for boot options, allowing users to select the device from which they want to boot, such as a hard drive, USB drive, or network boot. It provides a quick way to change the boot order temporarily without needing to enter the system BIOS setup.

F12 is particularly useful when you need to troubleshoot or restore systems, as it gives immediate access to the boot media options. The timing of pressing this key can be crucial, as it needs to be done quickly during the initial startup phase to register the input before the operating system begins to load.

Other keys like Esc, F2, and Delete serve different functions: Esc is often used to access the startup menu or BIOS setup in some scenarios, F2 typically enters the system setup (BIOS), and Delete may also access the BIOS or UEFI settings in certain configurations but does not provide direct access to the Boot menu. Hence, F12 stands out as the key that specifically meets the need for accessing boot options efficiently.
