you will have to contact dell regarding the downgrade option for the Bios. Or do a search on google. But Calling dell if it is under warrenty still would be the best option.

You will need to contact Dell by phone in order for them to reset your bios password. They will verify ownership and then provide information for resetting the password.

Password bios GJLPZK1-1F5A


this strikes me as being a dell desktop pc. if you need the bios password you must talk to dell who will ask a couple of questions to confirm you are the owner of the machine then give you the password.
www.dell.com - select your country then go to the contact us page.
