Startup menu

To change the computer startup settings, select Startup from the ThinkPad Setup main menu.
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.
• 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.

To change the startup sequence, do the following:
1. Select Boot or Network, then press Enter. The default boot list is displayed, showing the order in which
