Fixing the DISK BOOT FAILURE, INSERT SYSTEM DISK error and why it appears. Resolving the error DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER What is system boot fail

Quite often, we get questions about an error called “Disk Boot Failure” from our users. In addition, many users have detected a loss of files in their computers. In this article, we will look at the main causes of the error “Disk boot failure, insert system disk and press Enter”, and the solutions.

When you turn on your computer, the BIOS runs first, and then the operating system starts booting. If the BIOS cannot find the disk to boot from, you will certainly see the error message “Disk Boot Failure” in the screen. In addition, the boot process will be canceled and, as a result, you will not be able to access your data. If you want to fix this problem, you need to find out why it happens. Let’s look at a few basic reasons and, accordingly, the methods to eliminate them.

If the hard disk or partition is damaged, you will see a “Disk Boot Failure” error, because the operating system will not be able to boot.

The solution: in this case, you’d better replace the drive and reinstall the Windows operating system immediately.

Perhaps you have just installed a new hard disk into your computer. But when you try to start Windows, you still see the “Disk Boot Failure” message. In this case, the new hard disk is likely to be configured incorrectly.

The solution: after installing a new HDD, you need to insert the installation disc and restart the computer.

3. The hard disk is not connected correctly

In addition to incorrect configuration, your hard drive will not be able to communicate properly with your computer if it is not connected properly, and it will also lead to the “Disk Boot Failure” error.

The solution: in this case, you can turn off the computer, and then check the connection between the hard drive and the motherboard. After making sure that everything is correct, you can try starting Windows again.

4. Software settings conflicts

In addition, sometimes after installing any third-party software and restarting the computer you can also get this error. In this case, there is a great chance that the software conflicts with your operating system.

The solution: in such situations, the only way is to use a system recovery disc or simply reinstall your operating system. However, you may experience data loss in the process.

5. Boot Sector Viruses

Usually most viruses can only damage files on the hard drive, but there are some viruses that can damage the boot sector of the drive. If the boot sector is infected, the hard disk will certainly not be able to boot.

The solution: this situation is rather complicated. Removing viruses from the hard drive will cause a lot of problems in the BIOS settings and Windows system. It is quite difficult. Therefore, you must take daily precautions. For example, it’s easy to install a reliable anti-virus program and update it regularly.

6. Incorrect BIOS boot sequence

The BIOS is a program that works to find a bootable hard disk based on its boot order of devices when the computer starts. Therefore, if the BIOS boot sequence is incorrect, it cannot find a boot disk.

The solution: in this case, you can change the boot order in the BIOS. When you restart your PC, open the BIOS and go to the “Boot” tab. Then change the boot sequence so that the internal hard drive is the first boot option. Save the settings and restart your computer.

7. A Windows Failure

In addition, the failure to boot disk can also be caused by Windows system failures, such as damage to system files.

The solution: as in the above case, you must reinstall the Windows operating system.

We listed the main causes of the error “Disk boot failure, insert system disk and press Enter”. As we wrote earlier, this error is very often accompanied by loss of files. In case of a similar situation, we recommend using the data recovery software. For example, Magic Partition Recovery. This utility for file recovery includes various advanced algorithms that allow the program to return deleted files and folders that other recovery products do not even recognize.

Hello! A few days ago they brought me a system unit. They said it won't start. I thought I would just transfer Windows there, but that was not the case, it turned out to be much more serious, but it’s too early to talk about that :). Today I want to tell you about the error DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER, which can appear at any time and it is not clear why. This is exactly the error I encountered on that computer. I even took a photo of her, she looks like this:

I'll tell you in order. So I connected this system unit, launched it and am waiting for a miracle :) well, when some error pops up, because something is bound to happen anyway.

A message appeared stating that loading is not possible because there is no Floppy drive, etc. The battery that stores the CMOS memory and boot order simply ran out before complete happiness. Floppy was enabled in the BIOS, but physically disabled. But it is not important. I pressed F1, it seemed like a check and then the error DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.

Yeah, I've never encountered such an error before. But in principle, it is already clear that it says that there is no boot disk.

I rebooted the computer, disconnected that drive (Drive a), set the boot order with HDD in first place and tried to turn on the computer again. But I got this error again.

And then, after about the tenth reboot, one thing caught my eye: when the computer is being tested (POST), the hard drive is not visible in the test results. Like this? And like this:

You see, only one CD/DVD drive was detected, which was connected via IDE, and the hard drive that was connected via SATA was not detected by the computer. This means the cause of the error (in my case) has been determined; it is a problem with the hard drive.

I went into the BIOS and it wasn't there either.

Everything is clear, you need to check the hard one. Well, for starters, I just unplugged it and plugged it into another SATA connector. But the hard one was not detected by the computer, and I again saw the error. Then I decided not to play around and checked it on another computer. I connected it on another computer, via a different SATA cable, but the hard drive was not detected there either. That's it.

It means it’s just not working, I don’t know what happened to it, but it clearly needs to be replaced. That's what I told the owner of this computer.

This was the reason for this error in my case. But this does not mean that you also have serious problems with the HDD.

Other causes of the “DISC BOOT FAILURE, INSERT...” error

Let's look at a few more popular reasons why this error may appear, and of course, ways to get rid of it.

1. Check to see if there are any flash drives connected to the computer, and if there is a disc in the CD/DVD drive. By the way, I had an interesting case a long time ago. They brought the computer, too, and it won’t start. I started watching it, some error appears (I don’t remember exactly which one). I look, and there’s some kind of disk in the drive. I pulled it out and the computer started up normally. That's how we repair it :).

2. If the battery that stores the CMOS memory runs out, this means that after turning off the computer from the outlet, the BIOS settings will be reset. And of course the computer boot order will be reset. Be sure to replace the battery. Read more in the article.

3. Disconnect the floppy drive. This can be done in the BIOS (read about how to enter BIOS ) .

4. Go into the BIOS and check the system boot order. Install the hard drive in first place. I wrote more about this in the article. Also check if your hard drive is recognized by the computer (I had this problem, if you missed it, read the article first).

5. Check all cables connecting the hard drive and CD/DVD drive. Perhaps something just moved away.

7. If your HDD and drive are connected via IDE, then look at the information on the MASTER and SLAVE jumpers - there may be a problem with them.

That's all, if you have other ways to solve this error, then you can share them in the comments - I will be grateful! Best wishes!

This message, which appears when you turn on the computer, can be considered quite common. It says that the boot disk has failed. Next they suggest inserting the boot disk and pressing enter.

If such a message appears on your computer, this does not mean that the hard drive has necessarily failed, although this cannot be ruled out.

Possible reasons for the message:

• USB connectors contain flash drives or external hard drives;
• The computer has a disk drive with a floppy disk inserted into it;
• The wire has come loose from the hard drive;
• The boot priority in the BIOS settings is lost;
• The file system on the hard drive is damaged;
• One of the Windows boot files in the boot area of ​​the hard drive has become damaged;
• The hard drive has failed.

What should I do to resolve the “Disk boot failure insert system disk and press enter” error?

This message is synonymous with the message “Reboot and select proper boot device and press a key”, which has already been discussed. In order not to repeat ourselves, we advise you to familiarize yourself with it.

Possible solution is to move the hard drive cables

It describes in detail what wires need to be checked, how to check the boot menu, and also make sure that the hard drive is detected and displayed in the BIOS.

You can add that first of all, check the presence of flash drives and external hard drives in the USB ports, as well as the presence of floppy disks in the drives. If any of the above is present on the computer, then you need to remove it and try to turn it on again.

We will also once again describe the process of checking the order of boot devices using the example of another BIOS.

BIOS menu item Advanced BIOS Features

Here we make sure that opposite the inscription “First Boot Device” there is “Hard Disk”. The image above says "Removable". It is not right!

Next, check the “Hard Disk Boot Priority” menu item. There, the boot hard drive should come first. If you have several hard drives in the system, just try to swap them in this menu item using the “+” and “-“ keys. Don’t forget to save the settings using the “F10” key.

BIOS menu item - Hard Disk Boot Priority

If everything written above did not help, then you can try removing the hard drive and try checking it for errors on another computer, or try restoring Windows boot via a boot disk or flash drive.

Or if you have the opportunity to rearrange windows, then do this by first checking the hard drive for bad sectors and looking at its S.M.A.R.T.

If nothing helps you, then write down your situation in the comments or via .

Have you decided to work with your computer, turned it on, made yourself comfortable, but instead of a greeting you saw “DISK BOOT FAILURE, INSERT SYSTEM DISK” on the screen? This message means that the PC cannot load data from the system disk. If this error is not related to a broken hard drive, it can be fixed. But sometimes it occurs due to a hardware fault. In this case, it is better to entrust computer repair to professionals.

“DISK BOOT FAILURE, INSERT SYSTEM DISK” translates as “There is no boot disk, insert the system disk.” That is, the PC does not recognize the drive on which the OS is located. First you need to understand why this error occurred. And then figure out what to do with it. The problem may appear if:

• The loading order is broken. The PC is trying to “find” the operating system where it is not there.
• BIOS does not recognize the hard drive.
• The OS boot partition is damaged.
• The hard drive is not connected correctly.
• The hard drive is faulty.
• The motherboard is faulty.

How to fix?

Before you do anything, remove all disks, CDs, DVDs, floppy disks, flash drives and external HDDs. Leave only the drive on which the OS is installed. And try restarting your computer. If that doesn't work, unplug your CD and floppy drives. To do this, carefully disconnect their cables from the motherboard. And try starting your PC again. If after this the “DISK BOOT FAILURE” error disappears, it means that the BIOS settings are incorrect. The computer “looks” for OS files in the wrong place.

BIOS setup

BIOS or Basic Input Output System is activated when you turn on your PC. It controls the loading process. It indicates from which media the OS will be launched. And if you select a drive that does not have system files, an error will appear. Here's what you need to do to configure the BIOS:

1. Immediately after turning on the computer, press Delete, F1, F2, F11 or Esc. The key depends on the motherboard model. When you start the PC, a message will appear at the bottom of the display indicating which button is needed. The message will look something like “Press [key] to enter setup.”
2. The BIOS menu will be displayed. You can “navigate” through it using the arrows on the keyboard, open sections with the Enter button, and return to the previous menu with the Esc button. The bottom of the monitor should indicate the keys needed to interact with the GUI in the menu.
3. Go to the "Boot" tab and enter "Boot Device Priority". This is "boot priority".
4. The hard drive should come first. It is usually designated as HDD, SDD or Hard Drive. If the operating system is on another medium, make that one first.
5. Return to the main menu, go to "Exit" and select "Exit Saving Changes". Or press F10.
6. Try restarting your computer.

If you made any changes to the system or overclocked your PC, this could affect the BIOS. To return the settings to their defaults, in the Exit section, select Load Setup Defaults. The settings will be reset.

Hardware setup

If the BIOS does not detect the hard drive and even after setting it gives the “DISK BOOT FAILURE” error, what should you do in this case? Most likely, the problem is with the hard drive itself or with its connection. Or the motherboard has failed. The power supply may also be faulty.

In this situation, you will have to remove the cover from the system unit and fix the problem yourself. If you do not understand the internal structure of a computer and do not know where to connect a particular device, it is better to contact a service center. Although on the motherboard all the slots are different sizes. It is impossible to attach an unsuitable part to them.

Before you do anything, turn off your PC. Don't just finish the job, but remove the plug from the socket.

It makes sense to find out what condition the hard drive is in. Connect it to another computer (if possible), check whether the BIOS “sees” it and whether the OS boots from it. If it works, then the drive is working. Save your personal information just in case.

To resolve the "DISK BOOT FAILURE, INSERT SYSTEM DISK" error, try the following:

• Disconnect the hard drive cable from the motherboard and connect it again.
• Connect it to another SATA connector.
• Pull out the CMOS memory power supply (looks like a coin cell battery), wait about 30 minutes and put it back in place.
• Move the Clear_CMOS jumper (located on the motherboard, may have another name - CLRTC, Clear_RTC, CCMOS) from pins 1–2 to pins 2–3. Wait 20 seconds and return everything as it was.

After each step, check whether the hard drive is visible in the BIOS. To do this, the computer must be turned on. But for any manipulations inside the system unit, the PC must be de-energized.

If the malfunction occurs due to the power supply, it must be replaced. When it discharges, it negatively affects the operation of the computer - other errors may occur.

System Restore

Another cause of the problem is damage to the boot sector of the hard drive. This means that the part of the hard drive on which information important for the OS is located is inaccessible. In such a case, you need to restore system data. They will be written to good sectors.

You need an installation CD or other drive with the OS (an example with Windows will be considered). If you don't have it, you won't be able to reinstall the files. Since there will be nowhere to take them from.

1. In the BIOS, set the priority so that the system starts from the boot disk.
2. Insert the OS drive into the desired drive.
3. Once enabled, you can select the “System Restore” option.
4. Click "Startup Repair" and confirm the action. The OS itself will find problems and automatically solve them.
5. If that doesn't help, run the boot disk again. Just now select “Command Prompt”.
6. A window will open with a black background and white text. Type “Bootrec.exe /FixMbr” without quotes and press Enter. The customizer reanimates the master boot records.
7. You can also enter the command “Bootrec.exe /RebuildBcd”. All hard drives will be scanned for the presence of the OS.

If none of the above methods helped, it means that the hard drive is broken, or the motherboard or power supply has become unusable. The problem may also be a poor-quality cable or connection slot. It is quite difficult to repair them on your own. This requires professional knowledge and skills. It is better to entrust the repair to specialists. Or buy new parts.

This problem often appears if the boot order is changed or the BIOS is not configured correctly. In this case, you can fix the problem yourself. If the problem arose due to a hardware problem, it will not be so easy to solve.

Tell us if you encountered this error and if one of the listed methods helped you.

Do you get the "Disk boot failure" error when you turn on your computer? Many users encounter it. And what’s most offensive: it always appears unexpectedly, without any reason. Although, of course, there is always a reason. It just needs to be defined.

The literal translation into Russian is “The boot disk is damaged, connect another system disk and click Enter.” That is, they tell you that there are problems with the hard drive, but the reasons are much more trivial. And this is good, because they are easier to fix.

There are many ways to fix it yourself. And, before taking the computer to a service center, it is recommended to try them - you may be able to fix the error on your own.

How to fix Disk boot failure error?

I would like to note right away that the “Disk boot failure” error appears on any PC. The OS version can also be different - Windows 10, 8, 7 or XP. Therefore, if the computer writes “Disk boot failure”, you can try any methods. After all, they are universal.

There are several methods. Let's start with the simple ones:

1. Check to see if there is a disc in the drive. You may have recently copied files from it. Or installed the game. If the disk is in the drive, remove it and restart the PC. After this, the error may disappear.
2. Disconnect flash drives and external hard drives. Same case as above. Disconnect the flash drive and restart your computer or laptop. Sometimes it helps.
3. Disconnect the floppy disk drive (you are unlikely to use it today). This problem applies to old PCs, but it is no longer installed on new ones. To disable it, go to the BIOS and opposite the Drive A line, select “None”.

Also, first of all, you need to check the functionality of the HDD drive. First, look at the loading screen to see whether it is detected or not. If not, this is the first alarm bell.

Here it is recommended to check the hard drive with friends or acquaintances. If their computer also says “Disk boot failure” when turned on, then the hard drive is faulty (you need to buy a new one). If everything is fine with your friends, then the problem is on your side. We are looking further.

Very often this error appears due to incorrect settings in the BIOS. Moreover, they could go astray due to a dead CMOS battery. This usually happens due to the PC not being shut down properly.

Also, the settings are reset when the PC is abruptly turned off from the outlet. In this case, you need to replace the battery with a new one.

If you changed the BIOS settings yourself, then reset them manually. To do this, remove the CMOS battery, wait a few minutes and connect it again.

Sometimes an error when turning on the computer appears due to problems with the cable (the cable connecting the hard drive to the motherboard). Wiggle it or unplug it and plug it back in. If the cable is damaged, then replace it with a new one.

Perhaps your hard drive and DVD drive are connected via an IDE interface. This is another reason why it says “Disk boot failure” when starting the computer. The solution here is simple: disconnect the DVD drive and turn on the PC. If the error no longer exists, then you need to experiment with the SLAVE and MASTER master keys (they are located near the IDE socket of the HDD drive and the drive).

Checking and changing device boot priority

Another common reason why the Disk boot failure message appears when booting a PC is an incorrectly set priority for turning on devices. Here you need to go into the BIOS and set the settings so that the HDD drive boots first.

In Award this is done like this:

In AMI, this procedure is performed as follows:

If you have 2 hard drives, then you need to put the one on which Windows is installed in first place. If you don’t know, try both options one by one. In Award, the boot priority of two hard drives is configured in the “Hard Disk Boot Priority” item, and in AMI – “Hard Disk Drives”.

What to do if the "Disk boot failure" error still appears? Here are some tips taken from the comments of the users themselves:

1. Check the power supply. Although nothing clearly indicates this, this may be the problem. If possible, borrow a unit from friends or acquaintances and connect it to your computer.
2. Restore Windows. If the HDD drive is detected, works on another PC, everything is fine with the BIOS parameters, but the error still appears - perhaps the reason is that the system drive has been damaged. Try it (for the time when everything worked fine). Provided that it exists, of course.
3. Contact the service center or call a technician. If you have tried everything, but you cannot fix the Disk boot failure error, contact a professional for help. You have already done everything you could - let them look for the reason.
