How to recover the BIOS

In many cases, provided the 'bootblock' of your BIOS is not corrupted during a bad flash, the BIOS can often be recovered by following the recovery procedures detailed below. NOTE: this recovery method should not be followed for normal practice of updating your BIOS! As you will be invariably forced to flash from a floppy disk, you'll need both a known good working floppy drive (non-USB) and a good floppy disk.

 For Award BIOS

Make a bootable floppy disk*
Copy the Award flash utility & BIOS file to the said floppy disk
Create an autoexec.bat with "Award_Flash_Utility BiosFilename" in the content (e.g. awdfl823K w6378vms.130)
Sample on how to create an autoexec:
a. On Windows, open the notepad
b. On the notepad, write "awdfl823K w6378vms.130" (without the " ")**
c. Save the file as autoexec.bat

Boot up system with the said floppy (it will take less than 2 minutes before screen comes out)

Re-flash the BIOS & reboot.

*Need a bootable floppy disk? Look here:
**Make sure you enter the correct filenames for your flasher program and BIOS ROM file!


Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM

Insert this floppy disk in the floppy drive. Turn On the system and press and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file and recover the BIOS from the A drive.

When 4 beeps are heard you may remove the floppy disk and restart the computer.

 For new boards with AMI BIOS core 8 (4MB)

Discovered by Jack The Newbie:

Of course, the steps are similar to the standard AMI BIOS Recovery Procedure for internal floppy drives (rename corresponding BIOS File to AMIBOOT.ROM, hit CTRL + HOME after starting the system).

What has to be done (tested on P45 Platinum):

1. An optical SATA Drive needs to be connected to one of the Intel ICH10R SATA ports. {After a lot of testing, I found that it does not work with the same optical drive connected to the SATA Ports hosted by the secondary JMicron Controller.  Also, using an optical drive on the JMicron IDE/PATA port does not help either.}

2. A proper BIOS File has to be renamed to AMIBOOT.ROM and burned on an empty CD.

3. CMOS-Clear with main A/C power cable removed from PSU has to be performed. {If this step is not done, the system will reboot after pressing CTRL + Home and will not proceed with recovery procedure.}
4. Press CTRL + Home to trigger BIOS Recovery.  -> The system should enter BIOS Recovery Routine. {Will basically work with both USB & PS/2 keyboard.  However, a PS/2 Keyboard is recommended as the system will respond earlier to PS/2 Keyboard than to USB Devices.}

What should happen now:

1. After pressing CTRL + HOME the LED Status should change to "Intializing Hard Disk Controller" and there should be access to the optical drive connected to the Intel ICH10R SATA ports.

2. It can take up to 30+ seconds until the BIOS File that was renamed to AMIBOOT.ROM is found. {Drive Bay can be opened to try a different CD without turning off or restarting the system.}

3. When the system finds the BIOS File, LED Status will change to "Testing RTC" and there should be a message on the screen indicating that the Flash Recovery Procedure has started.

4.  Since the BIOS File is 4MB in size, it will take a while until the BIOS is actually reflashed.

Its also possible that BIOS recovery on boards with AMIBIOS8 can be done using a FAT-formatted USB stick, containing the renamed BIOS file. Be warned, in some circumstances it may take several moments before recovery procedure actually begins. 

If recovery does not work...

Locate the BIOS chip on your mainboard. If it is soldered directly to the PCB like...

...then you have no choice but to return the board to your supplier, or to MSI, for replacement.

If your BIOS chip is in a socket, like...

...then you may be able to source a replacement BIOS chip, either from MSI, or from a website such as

How to Repair the BIOS With a Flash Drive (5 Steps)

Step 1

Find out who made the BIOS on your broken computer, and also find out your unit's model number. Find this information inside the manual that originally came with your (now broken) computer.

Step 2

Open the Web browser on a computer that works properly. Go to the website of the company that manufactured your BIOS and download the latest version of the software for that BIOS. This software will be a free download on your BIOS' s product website. Download the file to the hard drive of the working computer.

Step 3

Insert your USB flash drive into the computer that works by way of a USB port. Then click "Start" and "Computer" and copy the BIOS update software onto the USB flash drive. At this point you can remove the flash drive from the computer it is currently in, as you are done with that machine.

Step 4

Insert your USB flash drive into the computer with the malfunctioning BIOS.

Step 5

Start the computer with the malfunctioning BIOS. Your computer will immediately boot off of the USB flash drive (as it won't be capable of booting off of anything else), and it will load the setup program for the BIOS software from the drive. Press "R" to select the "Repair" option, and allow the BIOS software setup utility to repair the software that runs your computer's BIOS. Once you have done this, you will have successfully repaired your BIOS with a USB flash drive.

HP Notebook PCs - Recovering the BIOS (Basic Input Output System)




The BIOS is the first software to run after turning on the computer. If the BIOS on your computer becomes corrupted, the computer fails to boot to Windows.

The BIOS can be corrupted during normal operation, through environmental conditions (such as a power surge or outage), from a failed BIOS upgrade, or damage from a virus. If the BIOS is corrupted, the system automatically attempts to restore the BIOS from a hidden partition when the computer is restarted. This document covers other steps to restore the BIOS if the automatic BIOS restoration does not work.

If you experience any of the following symptoms after restarting the computer, recover the BIOS.

  • Windows does not start and the caps lock or num lock keys blink, or the computer beeps 2 times

  • Power light or charging light continues to blink

  • A message displays

  • The computer stops at a black or blank screen when powered on

  • The computer turns on and you might hear the internal fan, but the display is blank and Windows does not start


For business computers, your IT department or local IT service might manage BIOS settings. Confirm this if you cannot access BIOS settings or restore the BIOS.

Reset the Embedded Controller

In some cases, the computer cannot boot to Windows because the data in the Embedded Controller (EC) is corrupted. Use this procedure to reset the EC.

  1. Turn off the computer and disconnect the power cord.

  2. Press and hold the power button for 11 seconds.

The computer turns on and the EC is reset.

If this does not recover your computer, see Reset the CMOS.

Reset the CMOS

In some cases, the automatic BIOS recovery fails because the Complementary Metal Oxide Semiconductor (CMOS) data is corrupted. The CMOS stores BIOS settings. Use this procedure to reset the CMOS and recover the BIOS.

  1. Turn off the computer.

  2. Press and hold the Windows + V keys, and then simultaneously press and hold the power button. After 2 to 3 seconds, continue to press and hold the Windows + V keys, but release the power button.

  3. When the CMOS Reset screen displays or you hear beeping sounds, release the Windows + V keys.

    At the completion of a successful CMOS Reset, a message similar to the following one is displayed.

    Successful CMOS reset button message
  4. Press enter to restart the computer.

Recover the BIOS

If your computer BIOS still does not reset, you can try to recover the BIOS using a key press combination or a USB recovery drive.

Recover the BIOS using a key press combination

Learn how to recover the BIOS using a key press combination.

Many HP computers have an HP BIOS Restore tool that might be able to recover the BIOS from an earlier version and restore basic function. This tool might not be able to recover the BIOS, depending on the cause of the corruption.

Use a second working computer with an active internet connection to create a BIOS recovery USB flash drive.

  1. Get the product number for the original notebook that requires a BIOS recovery. This number is typically found on a label on the bottom of the notebook or on the box it shipped in.

  2. Insert a blank USB flash drive into an available port on the second computer.

  3. Go to the HP Customer Support - Software and Driver Downloads page.

  4. Navigate to the product page for your computer.

  5. Select BIOS, and then review the details of the latest available version or the specific version recommended for the recovery. Confirm that it is the correct BIOS update before proceeding.


    Read the Details section to confirm that it applies to the computer. Installing the wrong BIOS could cause the computer to stop working.

  6. Click .

  7. Click Yes on the screen.

    Clicking Yes to allow the update to install

BIOS is one of the most important components of your PC since it’s in charge of starting your PC and checking your hardware.

Unfortunately, problems with BIOS can occur, and they can prevent your system from booting.

BIOS corruption can be a serious problem, but there are few ways to fix that on your Windows 10 PC.

BIOS corruption, how to fix it on Windows 10?

Fix – BIOS corruption Windows 10

Solution 1 – Reflash your BIOS

If you’re having problems with corrupted BIOS, you might be able to fix the problem simply by reflashing your BIOS.

Updating your BIOS is advanced and potentially dangerous process, therefore be sure to check your motherboard manual for detailed instructions on how to flash your BIOS.

We also wrote an article on how to flash your BIOS on Windows 10, so be sure to check it out for some instructions.

Solution 2 – Remove your motherboard battery

According to users, you might be able to fix the problem with corrupted BIOS simply by removing the motherboard battery.

By removing the battery your BIOS will reset to default and hopefully you’ll be able to fix the problem.

In order to remove motherboard battery you need to open your computer case, and in most cases that will violate your computer’s warranty, so keep that in mind.

If your PC is under warranty, it might be better to take it to the official repair center and ask them to fix the problem.

If you decide to perform this process by yourself, simply remove the battery and wait for 5-10 minutes for battery to drain completely.

After your battery is drained, insert it back to your motherboard and check if the issue is resolved. Some users are suggesting to replace your battery with a new one so you might want to try that as well.

If you’re using a laptop, be sure to remove both your laptop battery and motherboard battery to reset BIOS.

Some users also reported that you need to set your HDD mode in BIOS to AHCI after resetting your BIOS, so be sure to do that.

Find everything there is to know about your motherboard with the help of these tools!

Solution 3 – Reset your BIOS

According to users, you can fix this issue simply by resetting your BIOS.

There are several different ways to do that, and probably the simplest one is to enter BIOS and restore it to default values. To do that, follow these steps:

While your PC boots keep pressing Del or certain F key to enter BIOS. Usually there will be a message saying to press a certain key to enter SETUP.

If you can’t find this key, check your motherboard manual to see which key is used to enter BIOS. Once you enter BIOS, look for Load Setup Defaults option.

Run a System Scan to discover potential errors

Run a PC Scan with Restoro Repair Tool to find errors causing security problems and slowdowns. After the scan is complete, the repair process will replace damaged files with fresh Windows files and components.

This option should be located in the Exit section. Select Load Setup Defaults and save changes. Keep in mind that this process might be different depending on the version of BIOS that you’re using.

Another way to reset your BIOS is to change jumper positions on your motherboard. Most motherboards have a jumper next to the BIOS chip that allows you to reset it. To do that, follow these steps:

  1. Turn off your PC and disconnect all cables.
  2. Open the PC case.
  3. Look for a jumper that has CLEAR CMOS or something similar written next to it.
  4. Move the jumper to the clear position.
  5. Turn on your PC and turn it off.
  6. Now move the jumper back to its original position.

Keep in mind that you need to place the jumper in the appropriate position in order to reset your BIOS.

If you place it incorrectly you can cause permanent damage to your PC, so be extra cautions.

In order to avoid causing damage, we strongly suggest that you check your motherboard manual for detailed instructions on how to change the jumper configuration. Another way to reset your BIOS is to remove your motherboard battery.

We already explained this process in our previous solution, so be sure to check it out.

Read our comprehensive guide and learn how to use BIOS like a real technician!

Solution 4 – Remove your graphic card

Many PCs have both integrated and dedicated graphic card, and users reported that you can fix the problem with corrupted BIOS simply by removing your graphic card and connecting your monitor to the integrated graphic card.

Keep in mind that by removing the dedicated graphic card you might be violating your computer warranty.

Solution 5 – Use Windows Key + B key combo

According to users, you can fix this problem on HP computers simply by pressing Windows Key + B key combo while your PC boots. To do that, follow these steps:

  1. Turn off your PC.
  2. Press and hold Windows Key + B.
  3. While keeping these keys pressed, press and hold the Power button for 2 or 3 seconds.
  4. Release the Power button but keep Windows Key + B pressed until BIOS update screen appears or until you hear a beeping sound. During this process your screen might go blank for 40 seconds or more and you might hear beeping sounds from your computer. This is perfectly normal, so no need to worry about it.
  5. HP BIOS Update screen will now appear. Wait until the process is finished.
  6. After your BIOS is recovered, select Continue Startup button to complete the process.

Solution 6 – Use HP System BIOS Update Utility tool

According to users, you can fix this issue on HP computers by using HP System BIOS Update Utility tool. To do that, go to HP’s website and download the latest version of BIOS for your computer.

You might have to enter your PC’s model number or product number in order to download BIOS, so keep that in mind. After downloading new version of BIOS, you need to create recovery USB drive by following these steps:</p>

  1. Connect an empty USB drive to your PC.
  2. Double click the BIOS file that you downloaded.
  3. InstallShield Wizard will appear. Click Next.
  4. Accept the terms of service and click Next.
  5. In Location to Save Files window click Change.
  6. Select your USB flash drive, click OK and then click Next.
  7. HP System BIOS Update Utility will open. Click Next.
  8. Select Create Recovery USB Flash drive and click Next.
  9. Select your USB flash drive and click on Next.
  10. Wait while the files are copied to your flash drive. After the process is completed, click on Next.

After creating bootable USB flash drive, connect it to the problematic PC and follow the instructions from the previous solution.

These tools will definitely ease your task! Create multiboot USB drives with only a few clicks!

Solution 7 – Replace your motherboard

If the problem still persists, it might be that your BIOS chip is damaged and the only way to fix this issue is to replace your motherboard.

If your PC is still under warranty, be sure to take it to the repair center and ask them if they can fix the problem.

Corrupted BIOS can be a serious problem, but we hope that you managed to fix it by using one of our solutions.

Start your computer from a Windows 7 installation disc or USB flash drive

You might need to start, or boot, your computer using the Windows 7 installation disc or a USB flash drive if you want to:

  • Install or reinstall Windows 7.

  • Recover Windows 7 from a serious error. If your computer won't start Windows at all, you can access Startup Repair and other tools in the System Recovery Options menu from the Windows 7 installation disc or USB flash drive. These tools can help you get Windows 7 running again.

Note: If you use a Tablet PC or other computer with a touchscreen, you might need to attach a keyboard and mouse in order to use Startup Repair and other tools in the System Recovery Options menu.

  1. Turn on your computer, insert the Windows 7 installation disc or USB flash drive, and then turn off your computer.

  2. Restart your computer.

  3. Press any key when prompted to do so, and then follow any instructions that appear.

  4. When the Install Windows page appears, click Install now to begin the installation process or click Repair your computer to access system recovery options.

  5. Follow the instructions.

If the Install Windows page doesn't appear, and you aren't asked to press any key, you might have to specify that your computer uses its DVD drive or a USB flash drive as the first startup device. To do this, you need to change settings in the computer's basic input/output system (BIOS).

Note: Most newer computers can start from a USB device, but some older computers might not have this capability. For more information, check the documentation that came with your computer or go to the manufacturer's website.

Before you change BIOS settings, check the information that came with your computer or go to the computer manufacturer's website. Specific procedures for accessing the BIOS and changing settings can differ depending on your computer's manufacturer, or you might be able to choose which startup device your computer uses without changing BIOS settings.

Warning: Be careful when changing BIOS settings. The BIOS interface is designed for advanced users, and it's possible to change a setting that could prevent your computer from starting correctly.

  1. Turn on your computer, insert the Windows 7 installation disc or USB flash drive, and then restart your computer.

  2. Newer computers often display a startup (or boot) menu. On the startup menu, choose "BIOS setup," or "BIOS settings," or something similar.

    Procedures vary depending on the BIOS manufacturer. Usually, you must press a key (such as F2, F12, Delete, Esc) or a key combination immediately after you turn on your computer but before Windows starts. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer again.

  3. The BIOS setup screen appears. On the BIOS setup screen, choose the option called "Boot order," or something similar. Boot order settings might also be listed under "Advanced settings" or something similar.

  4. Select your DVD drive or USB flash drive as the first startup device. (The USB flash drive might be listed under "Removable devices" or something similar.)

  5. Save the setting changes, and then exit the BIOS.

  6. Restart your computer, and then start Windows 7 from the installation disc or USB flash drive as previously described.
