Startup menu
You might need to change the tablet startup settings. To do so, tap Startup from the ThinkPad Tablet
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.
