HI WLM13:
Thank you for your query.
From your post it sounds like you successfully changed the Windows password but now need to change the bios password. Depending on which model you have there are different options for entering the bios. Watch your start up screen and look for the prompt to enter the bios. It will only stay on your screen for 2 or 3 seconds so be ready. I am providing you a link to Bios Passwords click here. If you require further assistance please provide me with the exact model number of your computer. How Do I Find My Model Number or Product Number? click here.
