For starters, I doubt that clearing the CMOS will remove the bios password as Dell usually have a special chip that handles the bios password, otherwise it would be too easy to circumvent if all you had to do is remove the CMOS battery.

I was about to say that all you have to do us go into your bios to the Security tab and elect to change the bios password, at which point you'll be asked for your present PW then when you're asked for the new PW, you just leave it blank, but then you threw a speedbump into the mix, by talking about the Bios PW that Dell put in.

What Dell PW????

There is no such thing as Dell putting bios passwords on machines that they sell.

To remove the Windows log-in password click on the Start orb, then typs cmd in the Search programs and files.
 
cmd will appear above the Search box under Apps., right click on it and choose Run as administrator.
 
After the Elevated Commad Prompt opens type in netplwiz and press Enter.
 
User Accounts will open, you will need to remove the check from Users must enter a user name and password to use this computer
 
Click on OK.

Another window will open requesting that you enter your user name and password, do this, then click on OK

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I knew if I didn't explain it would open up a can of worms.Let me explain:I googled and asked for help from this site on how to boot from CD.I got many answers as how to do it.Only one thing wrong,when I enter the bios to make the suggested changes,every option is locked.When I look at the screen,UEFI and Legacy menu have brackets around them.When you look in the upper right hand corner it says everything in brackets is locked.Ok,so I got the bright idea of putting on a password,thinking this would help.Now when I try to get into the bios it asks for my password so I type it in and go on from there.Except the options are still locked so I did that for nothing.

The only thing I want to do is remove my password,that's all.Went to best buy where I bought it and explained that it is locked and he said Dell puts there own password on to prevent damage.He gave me a few to try but did not work.Hope that explains it.

Don't believe a word those guys told you.

It's all baloney.

You can start by removing your password, exactly as I described before.

 

all you have to do us go into your bios to the Security tab and elect to change the bios password, at which point you'll be asked for your present PW then when you're asked for the new PW, you just leave it blank

 

After that, you have to disable "Secure Boot".

If there is a "Fast Boot" option, disable that too.

Once secure boot is disabled, you should have access to the Legacy options too.
