The bios can be protected with a password to prevent others from accessing its settings. You have to enter the password to be able to access it, if you canÂ’t provide the correct one the access gets denied. The following method describes a way to recover the password if you forgot it or bought a used computer with a bios password.
CmosPwd is a free program that is able to display information about the bios once it is executed. You do need to create a bootable disk to be able to execute the program in dos mode. To create a bootable disk in windows right-click the disk drive and select format from the list of options. It is important that you enable the option Create an MS-DOS startup disk.
Once the disk is created copy the contents from the dos folder of cmospwd to the disk and restart the computer. You will have to remove all hard drives from the system if you do not automatically boot from disk drive. Type cmospwd.exe in the command line and the password should appear. Ignore the information about the other bios manufacturers and take a look at the one your computer is using.
Another possible method would be to start the computer in safe mode with command prompt which could work as well. You still need to access the files somewhere so make sure that the hard drive is accessible.
