Using the Boot Selection Menu program

The Boot Selection Menu program is a built-in, menu-driven configuration utility program that you can use to temporarily redefine the first startup device without changing settings in the Setup utility.

To use the Boot Selection Menu program, complete the following steps:

1. Connect a keyboard, monitor, and mouse to the console breakout cable, and connect the console breakout cable to the compute node.
   Attention: Use only the console breakout cable that comes with the compute node. Attempting to connect other console breakout cable types might damage the console breakout cable and the compute node.
2. Turn on the compute node (see Turning on the compute node).
3. Press F12 (Select Boot Device). If a bootable USB mass storage device is installed, a submenu item (USB Key/Disk) is displayed.
4. Use the Up Arrow and Down Arrow keys to select an item from the Boot Selection Menu and press Enter.
