I can't enter the BIOS because the computer boots too fast. If Fast Startup is enabled, you likely won't be able to enter the BIOS by pressing your computer's setup key because it'll boot up too fast. You can disable Fast Startup to fix this, or use a different method to enter the BIOS. To disable Fast Startup:
- Windows 11:
  - Type choose a power plan into the Windows search bar and click Choose a power plan in the search results.
  - Click Choose what the power button does in the left panel.
  - Uncheck "Turn on fast startup." If it's grayed out, click Change settings that are currently unavailable first.
  - Click Save changes.^{[9]

- Windows 10:
  - Type power and sleep into the Windows search bar and click Power & sleep settings.
  - Click Additional power settings under "Related settings."
  - Click Choose what the power button does in the left panel.
  - Uncheck "Turn on fast startup." If it's grayed out, click Change settings that are currently unavailable first.
  - Click Save changes.
This usually happens when the BIOS doesn't support the resolution of your monitor or there's an unsupported device connected to your PC. Try connecting a different monitor to your computer, and make sure no external devices other than your mouse and keyboard are connected when you try to enter the BIOS.

The setup key I'm using doesn't work to enter the BIOS. This could happen for a few reasons:
- Different motherboards use different setup keys, so you may just be using the wrong one. If your computer was prebuilt by an OEM manufacturer like Dell, HP, or Lenovo, look up your model and "Setup key" or "BIOS key" to find the right setup key.
- If you're using the right key but it's not working, you may need to hold down Fn as you press it.
- As soon as the computer turns off and back on, press the setup key repeatedly, but don't hold it down. Press it over and over again quickly until it boots to the BIOS or a menu with an option to enter it.
- If you're using a Lenovo laptop or desktop computer, try pressing Enter as soon as you see the Lenovo logo to enter the Startup Interrupt Menu. When the menu loads, press F1 to enter the BIOS setup utility.

The BIOS is locked, and I don't have the password. You can reset the BIOS to its default settings by removing the CMOS battery for about 5 minutes and then reconnecting it, or by temporarily moving the CMOS jumper slider to a different position.
- Removing/replacing the CMOS battery:
  - Turn off your PC and disconnect all cables and peripherals.
  - Open your computer and locate the CMOS battery on the motherboard. It's a round battery in a horizontal or vertical battery holder, or sometimes connected to a header with a wire.^{[10]

    Research source}
  - If the CMOS battery is in a holder, take a photo so you can remember which direction it's inserted in, then remove it from the holder for about 5 minutes before replacing it.
  - If it's connected with a wire, disconnect the wire for about 5 minutes, then reconnect it.
  - Reboot and enter the BIOS.
- Resetting with a jumper:
  - Turn off your PC and disconnect all cables and peripherals.
  - Locate the 3 pins near the CMOS battery, a round disc-style battery.
  - The jumper should have two positions—1-2, and 2-3. The default position is 1-2.
  - Move the jumper to 2-3 and leave it in place for 5 minutes.
  - Move the jumper back to the default position, reboot, and enter the BIOS.

You can't. The BIOS has been designed to require a password to deter potential hackers.

Question

How do I enter BIOS on a Windows 7 computer?

Community Answer

The operating system is irrelevant. Google your PC manufacturer or motherboard to find out what key to press on your keyboard. Once you know it, reboot your PC and press the key to enter the BIOS as soon as your PC powers on and the logo of your manufacturer shows.

If you need to reset the BIOS because you don't have the password, you'll lose any custom BIOS settings you've added. So, if you set the optical drive as the first device in the boot order, you'll need to make that change again after resetting the BIOS.
If your computer has a BIOS, the mouse won't be usable. If you have a UEFI, you should be able to use the mouse.
