Lenovo THINKSERVER 3821 - Manual (Page 266)

Using the Boot Selection Menu program
The Boot Selection Menu is used to temporarily redefine the first startup device
without changing boot options or settings in the Setup Utility.
To use the Boot Selection Menu program, do the following:
1. Turn off the server.
2. Restart the server.
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.
The next time the server starts, it returns to the startup sequence that is set in the
Setup Utility.
