Here we start with reasons why PC Not Booting To BIOS. The system firmware, known as the Basic Input Output System (BIOS), offers runtime functions to the Operating System. The Power On Self Test (POST) is carried out to inform the system that the Operating System may be loaded. Your computer won’t boot if POST is not successful.

These days, the BIOS has mainly been supplanted by the Unified Extensible Firmware Interface (UEFI). Nonetheless, the majority of UEFI firmware platforms offer support for traditional BIOS functions. As a result, UEFI is almost always meant when someone talks about the BIOS in a modern computer.

The names BIOS and UEFI are used interchangeably throughout this essay. You need BIOS access to change a few necessary settings. For instance, altering the RAM XMP profiles, your boot drive loading priority, turning on virtualization, etc. What to do if you can’t enter BIOS is one of the topics we cover in this post, among others. I hope you like your reading!

How To Fix PC Not Booting To BIOS?

Use UEFI Firmware Settings

The best way to access the BIOS on Windows 10 is through the UEFI firmware settings, provided your computer boots with the OS without issue.

  • Choose the Update and Security option in the Settings app.
  • Choose the Recovery tab from the left pane, then click the Restart Now button in the Advanced Startup section.
  • Choose the Troubleshoot button from the new window’s “Pick an option” menu.
  • Next, choose UEFI Firmware Settings under Advanced Options.
  • Press the Restart button to force the machine to enter BIOS.

Fix the Faulty Power Connector

You won’t be able to boot into BIOS if the motherboard or CPU’s power connector is improperly connected or defective. Please make sure the 24-pin connector on the motherboard is firmly inserted and that the cable itself shows no evidence of damage. Typically, the CPU has an eight-pin, 4+4-shaped connector.

  • Connect both ends properly.
  • Verify the appropriate connection of the wires’ other ends before inserting them into the PSU.

Troubleshoot The RAM Sticks

  • Your machine may be unable to boot into the BIOS or OS due to a Memory problem.
  • Ensure that each Memory stick is in good condition and properly positioned.
  • Turn off the computer by unplugging the power cord.
  • Find the RAM sticks on the motherboard by opening the case.
  • Remove them all from their places, then place them back in one at a time.
  • You should align the RAM module’s notch with the slot’s notch before installing each RAM module.
  • The tabs on both sides should click when the stick is seated correctly.
  • Avoid forcing the stick backward.
  • Try starting your computer again.
  • If it still doesn’t work, unplug all the Memory sticks and replug just one.

If the system is now booting, add each other RAM stick one at a time until you identify the problematic one that has to be replaced. Remember that a motherboard slot could occasionally be damaged, so you must test another slot to see whether it works.

Remove The BIOS Battery To Reset The CMOS

It would help if you uninstalled the CMOS battery to clear it since CMOS battery problems may result in boot troubles. What you ought to do is:

  • Disconnect and turn off any external devices plugged into your PC through a USB, HDMI, or other port.
  • Open the computer’s case and unplug the power cord.
  • Check the motherboard for a flat, coin-like battery that resembles a watch battery. The handbook for your motherboard can help you locate it if you can’t.
  • At this point, carefully remove the battery from its position. It can have a clip or lever holding it in place. The barrier can be removed manually or with a screwdriver, and the battery can be removed.
  • When the battery has sat outside for about 20 minutes, replace it. Ensure that it is placed correctly.
  • Shut the case, reconnect everything, and turn on the PC. Be aware that the CMOS battery has a lifespan of around ten years. It is safe to presume that the battery may be dead if you have owned the motherboard for that long or are using a used motherboard. To fix the problem, get a new CMOS battery and swap it out.

How To Boot PC To Windows?

Use this troubleshooting procedure if you’ve managed to boot the BIOS but still have difficulties starting the operating system.

How To Boot PC To Windows

Disconnect External Peripherals

There could be a conflict with one of the peripheral devices you’ve attached or their drivers that prevents the Windows operating system from booting. Unplug them, restart your computer, and check if the OS loads. Unplug any USB devices, such as the mouse, external hard drive, and others, and turn off the computer.

The power cable, the display cable for the monitor, and the keyboard should be the only cables still attached to your computer. To discharge any residual electricity, repeatedly press the power button. The system should then be turned on, and if Windows starts up, you have identified the issue. Until you identify the problematic device, restart the computer after each individual attachment.

Read The BIOS Error Messages

The system frequently provides an error message or a beep code to help you figure out where the issue is when the boot process cannot be completed. Either read the error message on the screen or pay attention to the boot-up sounds and search for its definition.

You can search for specifications on the manufacturer’s website or in the documentation for your motherboard or computer. If nothing is heard or seen, move on to the next item on the list to identify the problem.

Fix Possible Boot Device Issues

There may be an issue with the storage device on which Windows is installed or the boot order if your computer starts up to the BIOS but doesn’t load the operating system. The boot order determines how the system prioritizes various storage possibilities and searches them for Windows loading. The boot order should top the drive containing the operating system. The boot order can be determined as follows:

  • Take away all external disks and flash drives, then restart your computer.
  • During boot, access the BIOS as described in the preceding sections.
  • Locate the BIOS’s storage-specific Boot section. It could be referred to as Boot Priority, Boot Order Menu, or any similar term.
  • Place the main drive containing the OS at the top of the list. Disable all but one of the drives before starting the computer if you are still determining which one houses the OS. Until you locate the right drive, keep scrolling down the list. After giving it priority, turn on all other storage drives.
  • Remember to quit the BIOS after saving your changes.

What Are BIOS Functions?

You should be familiar with the BIOS operations and their roles to recognize and comprehend the issue you are experiencing.

  • POST: The Power-On Self-Test examines the computer’s hardware and verifies no faults before the BIOS installs the OS. Your computer won’t boot into BIOS or the operating system if it fails the POST test, which shows a hardware problem. You may hear a string of beeps that serve as error codes.
  • Bootstrap Loader: The BIOS will transfer control to the Operating System if the Bootstrap Loader identifies a capable one.
  • BIOS Drivers: The system uses these low-level drives to operate the PC’s hardware on a fundamental level.
  • CMOS: Complementary Metal Oxide Semiconductor is what the acronym stands for.

Using the configuration software, users can modify system and hardware settings, including time, date, and passwords.


In conclusion, PC Not Booting To BIOS, Windows users frequently experience problems with their BIOS not booting up on their PCs. In most circumstances, the fast booting startup feature on your system is enabled, preventing access to BIOS; thus, your system won’t normally boot to BIOS. If your system fails the Power-On Self-Test (POST) test before entering BIOS, another potential cause could be a hardware issue.
