Hi guys, I need my computer to boot from a dvd drive at the moment as I am trying to dual and boot Linux Mint. The only problem is I am unable to change the boot values. I know the commands are f5 and f6 to move down and up but using those just is not happening even though it did before. I also did creat a password for the BIOS not so long ago just to how this was possible and so not sure if that has anything to do with this. Also I am unable to undo what I have done regarding the BIOS password. If any of you can help I'd be very grateful. Thanks.

Pull out the CMOS battery for ten minutes and then reinstall. This will put you at the factory reset point and the BIOS should be accessable.

You have to remove that bios password and leave it blank.

I highly doubt that clearing the CMOS will do anything for you, in this case.

I'm almost positive that a bios password doesn't get cleared by clearing the CMOS.

And how do I remove the Bios Password? Thanks.

You will have to reset the bios back to defaults using the reset jumper on the motherboard. Just find out which three pins are your reset pins, move the jumper over to reset and leave on for 5 seconds, then just move them back. That should clear the password, but you will have to resetup your bios.

Well it turns out that changing the UEFI Boot BIOS in the Advanced BIOS settings from disabled to enabled solved the problem with  being able to change the values. I also mananged to clear the password by disabling the option to promt password on Boot.

 

This I think I can say is now resolved. Thanks for your time guys.

Sorry that I was slow to answer, but you clearly figured it out, so all is well that ends well.

Removing the CMOS battery resets the BIOS to the default settings, this includes the password.  Yes it will clear the password.

It will clear it in PC's. but most laptops have a special security chip that is not controlled or powered by the CMOS battery and getting around it involves the manufacturer or those after market guys who charge $50 to $100 to get you an unlocking code.
