Users have been dealing with booting issues since the very first version of Windows. There are various things that can prevent your system from booting normally. For example, system failure, damaged hardware, failed update installation, etc.

However, there are some booting problems that are more serious than others. One of these problems is definitely the BIOS issues, which prevents users from starting their computer. If you’re unable to exit BIOS, your computer is basically useless, because you can’t start it.

This isn’t a rare problem, as many users have encountered it already. In case you have the same problem, keep reading this article, because we’ve prepared a few potential workarounds, that might be of some help.

What to do if PC won’t exit BIOS

Solution 1 – Set BIOS settings to default

Maybe you accidentally changed some BIOS settings that conflict with your system. So, the safest bet, and the simplest possible solution is to simply reset BIOS to its default values. In case you don’t know how to do that, follow these instructions:

  1. Go to the Save & exit tab in BIOS
  2. Select the Load Optimized Defaults optionreset bios defaults
  3. Confirm the change

This is literally the simplest and the most basic solution for one’s BIOS issues. In case you’re still unable to exit BIOS after loading the default values, your problem is more serious. So, check out other solutions, but be careful with everything you do, because a wrong step can completely disable your computer.

Solution 2 – Make sure other components are not damaged

If some of the crucial hardware in your computer, like hard disk, CPU, or RAM memory are damaged, you won’t be able to boot your computer normally, or go past BIOS. In this case, BIOS is really not an issue, but you’re not able to go further, anyway.

Hard disk is the component that causes the most problems to users. Your system will usually tell you if the hard drive is damaged, but you can also check from BIOS, by checking if your hard disk is available in the list of boot sources.

When you make sure which component prevents your computer booting normally, change that component, and you’ll be able to start your computer again. If all your components are in a good shape, carry on with reading this article, we’re getting to more serious solutions.

Solution 3 – Reset BIOS

If software resetting didn’t help, we’re going to try the physical reset. Every motherboard has a CMOS jumper, which can be used for manually resetting BIOS. Before we continue with explaining what to do, we have to warn you. Be very careful while working with your motherboard, because you can easily damage it or other components if you’re not careful. So, if you’re not comfortable working with your hardware, ask someone who knows what he’s doing for help. Also, this method doesn’t work on laptops.

Now, let’s see what you need to do to manually reset your BIOS.

  1. Power off your computer, and unplug it from the outlet
  2. Open your case
  3. Find the CMOS jumper. It is located on your motherboard, and is usually labeled with  CLEAR, CLR, CLEAR CMOS, PSSWRD, or a variety of other labels.bios jumper
  4. You’ll notice that there are three pins, and the jumper covers only two. Move the jumper to other two pins. So, if the jumper is covering the first and second pins, move it to the second and third.
  5. Press the power button. Your computer won’t start because the power is turned off, but this will discharge any remaining power stored in the capacitors. When you do this, your BIOS will be reset.
  6. Now, just return the jumper to its original state
  7. Close the case, turn the power on, and start your computer.

Your BIOS is now restarted, and if there were any problems, they should be gone. However, there’s one more scenario which will leave your BIOS disabled, even if you reset it. We certainly hope that’s not the case with your BIOS, but we’ll explain it to you, anyway.

Updated your BIOS? Good luck!

Most of the people think that updating BIOS is like updating any other driver, but it’s totally different. Our ‘regular’ components, and the system itself are usually updated automatically, to improve security, performance, and compatibility. But updating BIOS can cripple your computer really bad, if something goes wrong. Because of that, it is not recommended to update BIOS, unless absolutely necessary.

If something goes wrong when updating your BIOS, it is very hard to get things back to normal. So, it is advisable to take your computer to a service, and ask for a professional help.

That’s all, we hope this article helped you resolve the problem with BIOS, and of course, that your computer is not permanently damaged. If you have any comments, questions, or suggestions, just let us know in the comments.
