How to fix PC automatically goes to BIOS

When you turn your computer on, regardless if it’s running Windows or Linux, it gives you a brief window during which you can boot to BIOS. This window tends to be longer if your system is older because the OS’s bootloader takes longer to load. On newer system, you only have a few seconds before you’re automatically booted to the desktop OS you’ve installed.

Fix PC automatically goes to BIOS

If you want to access BIOS on your computer, you must strike the right key the second you turn the system on. The key must be pressed before your OS begins to boot. If you turn your system on, and it goes straight to the BIOS, try the following fixes.

1. Check if OS is corrupt

Before you try anything else, check if the OS installed is corrupt. If it is, your system may be going to BIOS because it cannot find an OS to boot to.

Turn the system on.
Wait for BIOS to load.
Exit the BIOS by tapping the Escape key.
Wait for the OS to boot.
If the OS doesn’t boot, it may be corrupt and you will have to install it again.

2. Check Boot device

Your first boot device may be set to something other than the hard drive. Make sure you haven’t connected any external drives or USBs to the system. Remove discs from the optical drive.

Boot to BIOS.
Look for boot options.
Make sure the hard drive is set as the first boot device.

3. Run a hardware check

You may or may not be able to do this on your own. If you’re familiar with the hardware of a computer, you can run these checks yourself. If not, have a professional take a look.

Check for;

Loose cables, particularly for the hard drive. 
Check the CMOS battery. It may be time to replace it. 
The power supply unit and battery. Try to run the system on direct power.
Check the hard drive for errors or damage. If it’s damaged, you wont be able to boot to the OS that’s installed on it. 

Conclusion

A system normally won’t boot to BIOS unless there is a problem with the hardware or its configuration. Even if your OS is corrupt, you will see a message telling you no OS was found but you won’t be taken to the BIOS. More often than not, these problems are related to the power supply or the hard drive. A power supply can be repaired but a hard drive will have to be replaced in most cases.
