Changing the startup sequence

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 devices will be started up, even devices that are not attached to or installed on your computer are listed.

•Use the Boot submenu to specify the startup sequence that runs when you turn on the power.

•Use the Network submenu to specify the startup sequence that runs when Wake on LAN is enabled. Wake on LAN is commonly used by LAN administrators in corporate networks to get remote access to your computer.

2.Set the startup order by using the following keys:

•Use cursor keys to select a device.

•Use F6 or the combination of Shift and + to move the device up to a higher priority.

•Use F5 or – to move the device down to a lower priority.

•Use the combination of Shift and ! to exclude or include a device.

3.Press F10 to save the changes and restart the system.

To change the startup sequence temporarily so that the system starts up from a different drive, do the following:

1.Turn off the computer.

2.Turn on the computer; then, while the ThinkPad logo is displayed, press F12.

3.Select the device you want to start first.

Note: The Boot menu will be displayed when the system cannot boot from any devices or the operating system cannot be found.

The following table lists the Startup menu items.

Notes:

•Default values are in boldface.

•In each submenu, press the Enter key to show selectable options and select a desired option by using cursor key.

•Some items are displayed on the menu only if the computer supports the corresponding features.
