BIOS, which stands for Basic Input or Output System, is a firmware embedded on a computer's system board or motherboard. It serves as an interface between the hardware and the operating system, providing instructions for basic functions such as booting and time settings. In some cases, users may set up passwords in the BIOS or UEFI (Unified Extensible Firmware Interface) to enhance security.
Types of BIOS or UEFI Passwords
There are three types of passwords that can be set up in the BIOS or UEFI:
- System or User password: This password is required to log in to the computer and prevents unauthorized access to the system. Without this password, users cannot enter the BIOS, access the one-time boot menu, or boot into the operating system.
- Setup or Admin password: This password is necessary to access and modify the BIOS settings. It prevents unauthorized users from tampering with the BIOS configuration.
- HDD password: This password is required to access the hard drive and boot into the operating system. It prevents unauthorized users from accessing the hard drive and its contents.
If you have forgotten your BIOS or UEFI password, follow the instructions below to reset or clear it:

Recovering a Forgotten BIOS Password on a Dell Desktop
If you have forgotten the BIOS password on a Dell desktop, you can reset the CMOS or NVRAM to restore the BIOS to its factory default settings and remove the passwords. However, please be aware that clearing the CMOS or NVRAM using a jumper will reset all BIOS passwords, including the user password, admin password, and HDD password. It will not reset other passwords such as Windows login or online accounts.
The location of the PSWD jumper, which is used to clear the CMOS or NVRAM, may vary between different Dell desktop models. To find the exact location, refer to the documentation specific to your Dell desktop.
For a step-by-step guide on how to perform a BIOS or CMOS reset and clear the NVRAM on Dell computers, please consult the Dell documentation.
