Startup menu
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.
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
might be erased or overwritten.
Attention: 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.
