By setting a boot password, you can make your computer prompt for the password every time it is restarted.
You can set the boot password in the BIOS
when your computer is starting up. Usually the computer tells you when you can
enter the BIOS (press Del
to enter setup). The BIOS is different
for different computers. If you check the documentation for your computer, it
should tell you how to set a password. Or, if you feel comfortable exploring
your BIOS, simply enter setup and look for a security or boot option.
Note: Be careful when searching! Changes made to the
BIOS
can affect your entire computer. If you make a change that you are unsure of,
choose the Exit without saving changes
option.
This will undo any changes that you have made to the BIOS in a single session.
After you have set the boot password, choose the option to save changes and exit. This will restart your computer and ask you for a password every time you boot your computer and every time you re-enter the BIOS.
Be sure to remember this password. If you forget your password, it is extremely difficult to reset.
Since the new boot password gives no protection once the computer is turned on and the password has been entered, anyone can access your computer after it boots, unless you use a screen saver password in addition to a boot password.
