Startup menu
You might need to change the startup sequence of your computer. For example, if you have different operating systems on different devices, you can have the system start up from either of them.
Attention: After you change your startup sequence, you must be extremely careful not to specify a wrong device during a copy, a save, or a format operation. If you specify a wrong device, your data and programs might be erased or overwritten.
Attention: If you are using the BitLocker® drive encryption, you should not change the startup sequence. BitLocker drive encryption detects the change of startup sequence and locks the computer from booting.
Changing the startup sequence
Selecting Startup to display the Boot submenu.
To change the startup sequence, do the following:
1.Select Boot; then press Enter.
You can use the Boot submenu to specify the startup sequence that runs when you turn on the power. Refer to “Boot submenu” on page 115.
2.Select the device you want to start first.
3.Press Fn+F10 to save the changes and restart the system.
