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. 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, save, or format operation. If you specify a wrong device, your data and programs
