Turn off the computer. Then turn it back on and keep pressing the F8 button. It should bring you to a big menu and one of the options will be "safe mode". Choose "safe mode" and then let it boot up into safe mode and see if you can choose any of the users to log in with.

Remove password from hardrive in bios


Before your computer loads your operating system, it starts by running the BIOS program, which is extremely important because of its various options.

You can even set a password on your hard drive so that nobody can use your laptop computer without your password.

Once you put in the password into your hard drive, you can only remove it by accessing the BIOS system and deleting the password completely from the memory of your computer.

Save all of your important files on an external hard drive or similar storage device.
This is a precaution to avoid losing all of your files when making changes to the BIOS.

Then, restart your computer.
Wait for your computer's operating system to ask you to access the BIOS menu.

This may be at different times, depending on the manufacturer of your computer.
It can ask you when the manufacturer's logo comes up, or on a separate screen indicating for you to click the "F2" button on your keyboard to start.

Access the BIOS menu by clicking the key or combination of keys that you are informed to click. This information can be found in your computer's manual, but it changes between different companies.

Commonly used keys for this process are "F10", "F2" and "Delete."
Go to the BIOS option that contains your hard disk drive password.

The option that will lead you to this password varies immensely due to different laptop models, but it may appear as something such as "Advanced" or "Security."


Look for the option for changing the password, which should say "User Password," and then click "Enter." Put in the existing password and then click "Enter."

Do not enter any password into the blank fields asking you to enter a new password, and this will remove the password.

Exit the menu by clicking "Save and Exit." Click "Enter."

Need to reset bios password on Daytona-a rev 3.3 mboard


Enter the BIOS at power on, rather than booting windows, and go through the settings. Put in your old password and enter a new one as prompted on the screen.
If you bought this used, and there is a password from a previous owner, you can go to the system board and remove the small jumper that maintains the password lock for the BIOS. This should allow you access to the BIOS if you're locked out by a previous owner's password.

Ask for password to unlock system


Just hit the set up key as your machine boots up, usually, F2-F3 or F8.

Go to safe mode using the up-down arrows and where it says set/change password, simply hit the enter button, enter a new password in and close, using the save function.

You can now use that new password and are now officially the administrator!

Or else, you need some Windows password reset program to help you do that job.
