Startup menu
You might need to change the tablet startup settings. To do so, tap Startup from the ThinkPad Setup 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 tablet from booting.
Changing the startup sequence
To change the startup sequence, do the following:
1.Tap Boot. The default boot list is displayed, showing the order in which devices will be started up, even devices that are not attached to or installed on your tablet are listed.
2.In the Boot submenu, tap the menu item to specify the startup sequence that runs when you turn on the power.
3.Tap Save and Exit to save the changes and restart the system.
The following table lists the Startup menu items.
Notes:
•Default values are in boldface.
•In each submenu, tap the default value to show selectable options and select a desired option.
•Some items are displayed on the menu only if the tablet supports the corresponding features.
