How to Fix Disk Boot Failure Insert System Disk Windows XP, Vista, 7/8/10/11?

"Yesterday, I went to a computer shop. I purchased a new hard drive there and asked the IT person to install it on my laptop. When I came home, the computer failed to boot up. It said disk boot failure error. The IT operator told me that the hard drive had Windows 10 on it. Is there any way to fix this error myself?"

Have you faced a similar situation? Are you unable to turn your Windows computer on and facing a disk boot failure error? Don't worry. You can fix this error easily with the methods I provided in this article.

Disk boot failure error comes due to many reasons. Specifically, the users of Windows XP, Vista, 7/8, and even Windows 11 have reported this error. Therefore, this article aims to help you understand this error, why it happens, and how to fix it. Also, if you lost some data due to this error, my article will help you recover it.

All About "Disk Boot Failure"

Disk boot failure error occurs when the system fails to load the Windows correctly. What happens if the BIOS fails to detect a disk that has the operating system on it. Therefore, the BIOS throws an error indicating "DISK BOOT FAILURE – INSERT SYSTEM DISK AND PRESS ENTER". It means that BIOS wants you to add or insert a disk drive that has the operating system installed on it.

To understand why BIOS does this, one needs to understand the booting process of a computer. Whether you are using Windows Vista, 7/8/10, or even Windows 11, the process of booting the computer up remains the same.

Booting Process

  1. You turn the computer on by pressing the Power button.
  2. A POST (Power-on self-test) starts to happen as soon as you press the power button.
  3. BIOS settings start to find the boot device where the operating system should be installed.
  4. From the boot device, BIOS loads the operating system installed in that disk.
  5. BIOS gives complete control to your operating system.

These 5-steps happen in quick succession. If any of the steps fail, a boot error will come. In our case, your BIOS fails to perform the third step, throwing disk boot failure error.

Why "Disk Boot Failure" Happen?

Now you understand what disk boot failure error is and may wonder why it happens. In most cases, your computer may work fine on the closure but throws a disk boot failure error when you turn it back on. There are multiple reasons which can cause this error in the first place. Let's see the reasons below one-by-one.

1. Disc Stuck in the Drive

One reason for disk boot failure is when a disc is stuck inside the drive. The disc that would help BIOS to detect the operating system may be stuck. If this is the case, you can try removing the disc and inserting it again.

2. Incorrect Boot Sequence

Your BIOS settings have the option to see the order for boot sequence. BIOS will check the boot device from this order. If the order is wrong, meaning that your boot device isn't set to be first to load, a boot disk error will come.

3. You Have Installed a New Hard Drive on Your Computer

Installing a new hard drive on your computer without configuring it can change up the BIOS settings. BIOS might confuse your more recent hard drive with the older one and hence fail to find the boot device, resulting in disk boot failure.

4. You Have an Unplugged Hard Drive

Sometimes, your disk drive may be loosely attached to your computer case. It can also cause BIOS to fail to detect the boot disk and renders the disk boot failure error. Make sure to check if your disk drive is correctly connected with your computer system.

5. Damaged Disk

A damaged or corrupted disk will not allow the BIOS to load the operating system for it. Users have also reported that the cause of their disk boot failure error was their damaged disk. If this is the case, you need to repair your boot disk.

6. Corrupted System Files

Another common reason for disk boot failure error is corrupted system files. Your operating system files can be corrupted due to any reason. Hence, BIOS will not be able to load it properly. For this case, you need to repair the corrupted files.


Fix "Disk Boot Failure" on Windows

In summary, you can say that disk boot failure on Windows occurs due to BIOS being unable to find the disk with an operating system installed on it. With that said, various reasons can cause the error, which was mentioned above.

The good news is you can fix the disk boot failure error. There are many complex solutions on the internet. Still, here you will see a list of compiled solutions that are straightforward. If you follow the below-listed methods step-by-step, you can fix the disk boot error quickly.

Let's see the solutions step-by-step below.

Fix 1: Change BIOS Boot Order

One leading cause of disk boot failure error in Windows Vista, 7/8/10, and even Windows 11 is the boot order of disk drives in BIOS settings. In BIOS settings, your disk drive with the operating system must be booted as the priority. If that is not the case, then you might see a disk boot failure error.

To check the boot order settings in BIOS, follow the below steps:

Step 1: Restart your Computer.

Upon restart, you need to press the F2 key continuously to enter the BIOS settings. (In some computers, the key may be different. If F2 is not the key for your system, please check the internet to find your computer's relevant key. Usually, "Del, F8, F10, or F12 keys" work.

Step 2:  In boot settings, use arrows keys to navigate to the Boot tab.

Step 3: Change boot order and make sure to put your disk with the operating system as a top priority.

bios settings interface screen

Step 4: Press the F10 key, and BIOS will save the new settings and restart.

After performing this step, your system will boot up normally with your operating system without throwing the disk failure error.

Fix 2: Check HDD for failures

Sometimes, your Hard Disk Drive can have issues with it. Those issues can likely cause the disk boot failure error. The limitation of this method is that you need to access your system to perform this method.

To check your HDD for issues, follow the below steps:

Step 1: Open File Explorer.

Step 2: Right-click on your drive with the Windows icon on it and click on properties.

opening settings of drive with Windows OS installed on it

Step 3: Move to the Tools tab in properties and then click the Check button on it.

selecting the check option

Step 4: Choose the Scan Drive option.

Step 5: Wait for the hard drive scan to complete.

The process may take a little while. Once the process is complete, the scan results will appear. You will be able to see the list of errors associated with your hard drive.

Fix 3: Run chkdsk

A common reason that users have reported that caused disk failure error was due to their damaged disk. Damaged disk in Windows operating system can be fixed using chkdsk command. However, it would help if you had a Windows installation disc to use this method.

Follow the below steps:

Step 1: Boot your system through a Windows installation Disc.

Step 2: Choose to Repair your computer option.

Step 3: Select your Windows Installation drive and then click on the Next button.

Step 4: In system recovery options, select the Command Prompt.

Step 5: Type the "chkdsk C: /f" command in the terminal. (Replace C with your drive letter where your Windows is installed)

running the chkdsk command to repair the drive

After step 5, wait for the process to complete. Once the process is completed, you can restart your computer and see if that fixes the disk failure error for you.

Note: Make sure to remove the installation disc before restarting.

Fix 4: Remove Newly Installed Hardware

Disk boot failure error can also occur if you attach a new hard drive to your computer and do not configure it properly. Follow the below steps to fix it:

Step 1: Remove the newly installed hard drive from your computer and restart the computer.

Step 2: Check your hard drive cables where your operating system is installed. Make sure they are appropriately connected.

Step 3: Check your hard disk jumpers.

All three steps can help you fix the disk boot failure error. You don't need to follow all three steps. If you can fix the problem with step 1, that should be enough. All three steps are independent solutions to fixing your disk failure error.

Fix 5: Repair Corrupted Operating System

Your corrupt operating system will also cause disk boot failure error. However, repairing a corrupt operating system is relatively easy. You need to have a Windows installation disc or a bootable Windows USB drive to work with this method. Follow the below steps:

Step 1: Boot your system through a Windows installation Disc.

Step 2: From Windows Setup, click the Next button.

Step 3: Choose the "Repair your computer" option from the interface.

Step 4: Select the "Troubleshoot" option.

Step 5: In Advanced Options, select the "Startup Repair" option.

Once the startup repair is complete, restart your computer and see if it fixes the computer.

Summarizing

These are some of the most used and accessible solutions to fix disk boot failure error in Windows Vista, 7/8/10, and Windows 11. Any of the solutions mentioned above can work for you. You need to pick the appropriate solution by seeing its limitations.

Usually, just running the HDD failures method can help you detect the exact error associated with your hard drive. But, if you are unable to access the computer in the first place, you can check if your hard drive is connected correctly or not.

About “Disk Boot Failure

The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations.

Description and Symptoms

The error messages, alerts, warnings, and symptoms below are tied to this error.

Symptom 1: “Disk Boot Failure” error screen on startup

Every time a computer is turned on, as part of the boot process the BIOS tries to find a bootable drive to continue the loading process by starting its first sector. However, if BIOS is unable to find a drive to boot from, then a “Disk Boot Failure” error screen is displayed and the boot process is halted.

Here is an example of “Disk Boot Failure” error screen for all versions of Windows:

Disk boot failure error screen

DISK BOOT FAILURE - INSERT SYSTEM DISK AND PRESS ENTER

Causes of this Error

This error has been known to occur as a result of one of the following causes:

Cause 1: Incorrect BIOS boot order

The most common cause of this error is an incorrect order of boot devices in BIOS. Usually BIOS tries to find a bootable drive according to its boot device order, so if a PC has a floppy drive set to a higher priority than a hard drive, and there is a floppy disk inserted – then the PC tries to boot from a floppy disk, and a error message is displayed.

Cause 2: Faulty data cables

Like all components of our PC’s, hard drive data cables tend to deteriorate as the time passes. If the same data cable was used for several years(or even the same one across several computers), then it might me the cause of periodic read/write errors that can affect the loading process.

Cause 3: HDD is damaged

A hard drive can become damaged or inaccessible due to read/write errors, power outages, or virus attacks. If that’s the case, then the drive should be checked for errors and scanned for viruses to make sure that it works correctly.

How to Perform a Startup Repair in Windows 7

Startup Repair Didn't Fix the Problem?

It's possible that Startup Repair didn't fix whatever problem you were having. If the Startup Repair tool determines this itself, it might automatically run again after your computer restarts. If it doesn't automatically run but you're still seeing problems with Windows 7, repeat these steps to run Startup Repair again manually.

Also, be sure to read the Important note on Step 1.

If it becomes apparent that Startup Repair isn't going to solve your Windows 7 problem, you do have some additional recovery options including a System Restore or a System Image Recovery, assuming you have previously backed up your entire computer.

You could also try a Parallel Install of Windows 7 or a Clean Install of Windows 7.

However, if you've tried a Startup Repair of Windows 7 as part of another troubleshooting guide, you're probably best served by continuing with whatever specific advice that guide is giving as your next step.

Conclusion

Disk boot failure error can prevent the BIOS from loading the operating system. It happens because BIOS fails to recognize the disk where your OS is installed. As a result, you will face a black screen and won't access your system.

Many causes of disk boot failures include unconfigured hardware, damaged OS, incorrect boot order, disc stuck, improper HDD connection, etc. In our opinion, you must always check if your HDD is connected correctly before moving to any other solution. If it is, then you can try OS repair options.

Also, suppose you lose data due to disk boot failure or during the process of fixing it. In that case, you can use Wondershare Recoverit tool which is reliable. It is highly recommended because I have personally tried and tested it.

How to Fix Windows 7 When It Fails to Boot

Whether caused by a virus, a new operating system or by simple mistake, being faced with an "Operating System not found" or similar error during your computer system's boot up can be a nerve rattling experience. Assuming you have Microsoft's Window 7 installed however, do not fear, such a boot error can often be resolved in just a few simple steps.

First, check your BIOS and hardware

In many cases, having Windows 7 fail to boot may be as simple as having your BIOS set with an incorrect boot order sequence. It can be quite common if you have more than one hard drive installed in your computer and your BIOS gets reset. Usually you can access your BIOS seconds after your computer turns on by pressing the Delete button or by pressing a specific function key. Once in the BIOS, check to see that your system drive is listed appropriately in the boot order sequence; you may need to refer to your motherboard manual for help.

Another possible reason for Windows not being detected upon start up is a hardware issue. If your BIOS is unable to detect your system drive, check to make sure all the cables are plugged in properly. If your hard drive is making an odd noise, such as a clicking sound, your hard drive may be broken. Finally, it is possible that the hard drive is having data corruption issues, which has damaged important system data, such as the Master Boot Record (MBR). If you suspect a faulty hard drive, it may be a good idea to backup and scan your hard drive for errors from another computer and possibly consider buying a replacement. Trying to repair a boot problem on a damaged drive can possibly lead to even more data loss, so backup your data before attempting anything.

The MBR and other important boot data can also be damaged by trying to install an earlier version of Windows, such as Windows XP, alongside Windows 7 and by third-party programs, such as viruses. In the case of a virus, it is recommended that you run a virus scan of the drive before attempting any repairs as otherwise it could lead to more data loss. It is further possible to achieve the appearance of damaged boot data by having the wrong drive partition set to active, which can be the outcome of an overly curious Windows user with administrative permissions.

Fixing the MBR and other start up problems in Windows 7 is most quickly accomplished by using the Windows 7 Installation DVD. If you do not have a Windows 7 Installation DVD however, you can alternatively use a Windows 7 System Recovery Disc, which we will show you how to create further down in this article.  If you do not yet have either a Windows 7 Installation DVD or a recovery disc, do yourself a big favor and make a recovery disc right away to avoid any unnecessary headaches down the road.

Fixing the Master Boot Record (MBR)

Step one: Turn your computer on, booting from either your Windows 7 Installation DVD or Windows 7 System Recovery Disc.  Remember, you may need to change the boot order inside your BIOS to have the your DVD drive boot first.

Step two: After the installation or recovery disc loads, if prompted, select your language settings and then continue.  If you are using the installation DVD, when prompted by the following screen select Repair your computer.

Step three: The computer will take a moment now to scan itself for any Windows installations, after which you will likely be given a choice to select which installation you wish to repair.  Select the appropriate Windows installation from the list and then continue. If by chance a problem is detected in one of your Windows installations at this initial stage, the system may also ask you if it can try to repair the problem automatically. It is up to you if you wish to let the system try to repair itself, but otherwise just select No

Step four: Once you have reached the System Recovery Options screen, as shown below, you will be faced with a list of choices that can aid you in repairing a damaged Windows 7 operating system.  If you wish to try the Startup Repair option first, it is often successful in automatically fixing many different start up issues, but in this article we will be using the Command Prompt option to resolve our problems manually. So, click Command Prompt to continue. 

Step five: Now sitting at the command prompt, enter the following command and then press enter:

bootrec.exe /FixMbr

If successful, you should be greeted with the message The operation completed successfully.  That's it!  Your Master Boot Record has been repaired.

While the above command does fix the MBR, and sometimes that is enough, there still might be an error with the system partition's boot sector and Boot Configuration Data (BCD). This might occur if you have tried to install another operating system alongside Windows 7, such as Windows XP.  To write a new boot sector, try the following command:

bootrec.exe /FixBoot

If you are still faced with your Windows 7 installation not being detected during start up, or if you wish to include more than one operating system choice to your system's boot list, you can try the following command to rebuild your BCD:
       
        bootrec.exe /RebuildBcd

The above command will scan all your disks for other operating systems compatible with Windows 7 and allow you to add them to your system's boot list. If this fails, you may need to backup the old BCD folder* and create a new one in its place with the following commands:

        bcdedit /export C:\BCD_Backup

        c:

        cd boot

        attrib bcd -s -h -r

        ren c:\boot\bcd bcd.old

        bootrec /RebuildBcd

*Some users also find simply deleting the boot folder and retrying the above steps effective at resolving boot issues, but it is not recommended.

How to create a Windows 7 System Recovery Disc

Windows 7 makes it easy to create a System Recovery Disc if you already have Windows 7 installed and running. 

Step one: Click Start > All Programs > Maintenance > Create a System Repair Disc

Step two: Insert a blank CD or DVD into your disc drive.

Step three: Click Create disc and let the program do its thing.

That's it! It only needs to write about 140- to 160-megabytes to the disc, depending on whether your OS is 64-bit or 32-bit, and that should only take a minute. If you do not have a CD/DVD-R drive to create a recovery disc with, you can alternatively download the ISO image of the Windows 7 System Recovery Disc and use it to make a bootable USB flash drive.

How to create a Windows 7 System Recovery USB flash drive

Step one: If you do not have a DVD drive, download the appropriate Windows 7 Recovery Disc image from Here. You will need a torrent client for this step, such as µTorrent. Alternatively, if you have a DVD drive, you can use an existing Windows 7 Installation DVD or a Windows 7 Recovery Disc when at step seven. 

Using a Windows 7 Installation DVD at step seven will also allow you to install Windows 7 via USB, not just recover a damaged system; very useful if you have a netbook!

Step two: Open a command prompt with administrative rights. To do this, click Start > All Programs > Accessories and then right click Command Prompt, followed by clicking Run as administrator.

Step three: After accepting any UAC verification questions, you should now be at the command prompt. Make sure your USB flash drive is plugged in and then type DiskPart, followed by pressing Enter.

Step four: Type List Disk and then press Enter. Determine which disk number corresponds to your USB flash drive. In the following scenario, Disk 1 corresponds to our USB drive since we know our USB drive has a capacity of 2-gigabytes.

Step five: Enter the following commands in order, changing the disk number to the disk number listed for your USB drive.  Warning - the following commands will erase everything on your USB drive or the disk you select.

        Select Disk 1

        Clean

        Create Partition Primary

        Select Partition 1

        Active

        Format FS=NTFS

Step six: After DiskPart successfully formats the USB drive, which might take a few minutes, you will want to enter the following commands:

Assign        Exit

Step seven: You will now need to copy the contents of the ISO image you downloaded, or the contents of a DVD you wish use, to the USB flash drive.  There should be two folders and a file in the ISO image that need to be copied. To extract the files contained within an ISO image, you will need to use a program such as WinRAR. You can download WinRAR from here.

Step eight: Now that the files are copied, we will want to make the USB drive bootable. To accomplish this however we will need to download a small file called bootsect.exe; it can be downloaded from here (opens in new tab) or here. The file can also be found in the boot directory of the Windows 7 Installation DVD.  Once downloaded, place the bootsect.exe file in the root directory of your USB flash drive.

Step nine: Back at the command prompt, we will want to change the current directory to that of the USB drive and run the bootsect command. In our case this is drive E, so we will be using the following respective commands:

          e:
          bootsect /nt60 e:

The bootsect command will update the target volume with a compatible bootcode. If all goes well, you should now have a bootable USB recovery drive; just remember to add the USB drive to the boot list in your system's BIOS for it to work upon start up.
