Hi all! Once I got a system unit that did not start according to the owner. It's okay - I thought, most likely problems with Windows. However, as it turned out, this is not the case, more on that below. Today I will tell you about the error faced by hundreds of people. The reason for this error is not known at first glance, but if you look closely, you can find ways to solve this problem. This is exactly the error I encountered on the above computer. How this error looks like can be seen on the poster of the article.
I connected and launched this system unit, a message appeared that there was no Floppy, etc. This is due to a dead battery that stores the boot sequence and CMOS memory. In BIOS, the drive was enabled, but in fact it was disabled, so I pressed F1 to skip all the information. And then at the time of the check, the error DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER came up.
To be honest, I personally encountered such an error for the first time, but from the name you can guess that the problem is the lack of a boot disk. After rebooting the system, I turned off the drive, and put the hard drive in priority in the first place. However, the same error popped up after that.
I rebooted the computer several more times, changing various settings in the BIOS, and then suddenly I noticed that when the computer was being tested when it was turned on, the HDD was not visible in the test results.
As you can see in the photo, the computer saw only the CD / DVD drive, and the hard drive connected to the SATA connector was not detected by the system. It turns out in my case the problem is in the hard drive. There is no HDD in BIOS either.
Perhaps the problem is in contact and I disconnected the SATA cable from one socket to another. Unfortunately this didn't work. After I checked this hard drive on another computer, connecting it through a different cable, and as a result, the HDD was not detected either. Therefore, the hard drive is simply defective and should be replaced. I also told the owner of that computer.
This was the reason for my error DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER, but this does not mean that you also have such an error due to a faulty hard drive. Let's look at the causes of such an error.
1. The computer's boot order will be reset if the battery that also stores the CMOS memory runs out. When you turn off the computer from the power outlet, the BIOS settings will also be reset. Therefore, I advise you to replace the battery.
2. Disable the floppy drive in BIOS. I suppose you still don’t use a Floppy drive, because flash drives have long been replaced.
3. In order for the computer to start correctly, make sure that there is no disc in the CD / DVD drive and no USB flash drive (s) connected. I had one funny incident. Somehow they brought me a system unit for repair, it did not start, it gave an error (to be honest, I don’t remember which one). Look in the DVD-ROM and there is some kind of disc inserted. By popping this disk out, the computer was repaired. Yes, friends, it happens.
4. In order for the computer to start immediately from the hard drive, it is necessary to set the boot priority in the BIOS. You need to install the HDD in the first place and reboot the system. Also make sure that the computer sees the hard drive.
5. If you have a drive and a hard drive connected via the IDE interface, then try disconnecting the CD / DVD drive and starting the system again. If the computer starts normally, then experiment with the SLAVE and MASTER jumpers, which are located near the IDE socket of the hard drive and CD / DVD drive.
6. Carefully check the cable connecting the hard drive to the motherboard, you never know what has come loose over time.
I hope this article will help you with your current problem. If you know other ways to fix this error, you can describe them in the comments! That's all!
Hello friends! Sometimes when you start the computer, you can see the message DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER on the monitor screen. If you translate this error literally, it will turn out: "it is impossible to boot from the disk, insert the system disk and press enter." There is only one logical conclusion with such an error - a problem with the boot device (hard drive, drive or inserted USB flash drive). Today we will consider the causes of such an error and how to eliminate it.
Before we begin, I will tell you a case with one computer. Somehow they brought me one system unit for repair. The owner of this machine said that the computer does not start and gives the error " DISC BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER».
The first step is to clarify what the last actions were carried out with the PC, what was its behavior recently, which I did. All this is necessary in case of any computer breakdown (and not only) in order to find out as much as possible where to dig and what detail to sin on. The owner of this PC said that everything happened spontaneously, while there were no mechanical effects, but recently rattling sounds were heard. The first thought is a problem with the HDD, because this happens when the hard drive "crumbles". This speculation became a fact when I noticed that when the computer was turned on, when the hardware was being tested, the hard drive was not displayed.
It turns out that the hard drive was not detected by the system, although at that moment it was connected to the SATA connector. Climbed into the BIOS of the computer - HDD is not displayed. Then I connected this disk to my PC and, oddly enough, it was not recognized. There is only one conclusion - problems with the hard drive. By the way, I recently wrote an instruction that, if you wish, you can read it so that you know what to do in a similar situation in the future.
After the hard drive was replaced, the system saw the new hardware and recognized it. After installing the operating system and installing all the necessary programs, the computer returned to its happy owner in working order. Here is such a short story from life, where I first encountered the error BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. If you see something like this on your screen, don't panic, because this does not mean that your HDD has also crashed, there are other reasons. Let's take a look at them.
Causes of the DISC BOOT FAILURE error
Step one. If you have a Floppy drive in your computer, then I advise you to disable it both physically and in the BIOS settings. If you don't have it, then move on.
step two. Check carefully all cables, loops connecting devices to the motherboard. Sometimes, with poor contact, you can see various errors, including the one described in this article.
Step Three. The boot order of devices can be knocked down due to a dead three-volt battery, as it keeps the CMOS memory in working order. A situation like this can easily cause a BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER error. Therefore, in this case, I recommend buying a new battery and replacing it.
Step Four. Make sure your drive is empty, i.e. without a CD, and check if the flash drives are connected now. The thing is that sometimes in the BIOS settings they put the CD / DVD drive or USB flash drive in the first place in the priority of boot devices. If in this case a non-boot disk is inserted into the drive or a USB flash drive into the USB socket, then it is likely that the above error or similar will pop up. Therefore, I recommend removing the disk and all flash drives from the computer.
Step Five. Make sure that the computer really sees the hard drive in the BIOS, and also look at the device boot priority - the HDD must be installed in the first place so that the system boots immediately from it.
Step Six. There are cases when the hard drive is connected in parallel with the CD / DVD drive via an IDE cable. In such a situation, I advise you to disconnect the IDE cable and power from the drive. If this helped and the computer starts up again as before, then I recommend experimentally switching the jumpers located near the cable socket to the MASTER and SLAVE modes.
Friends, I will be very glad for your comments - did this instruction help you or maybe you solved a similar problem in some other way. That's all! Thank you for your attention!
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.
Have you decided to work with your computer, turned it on, made yourself comfortable, but instead of greeting you saw “DISK BOOT FAILURE, INSERT SYSTEM DISK” on the screen? This message means that the PC cannot load data from the system drive. If this error is not related to the breakdown of the hard drive, it can be fixed. But sometimes it occurs due to a hardware malfunction. 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:
- Load order broken. The PC is trying to "find" the operating system where it does not exist.
- The BIOS does not recognize the hard drive.
- OS boot partition corrupted.
- The hard drive is not properly connected.
- The hard drive is defective.
- The motherboard is faulty.
How to fix?
Before doing 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 drives and disk drives. To do this, carefully disconnect their cables from the motherboard. And try to start the PC again. If after that the error "DISK BOOT FAILURE" disappears, then the BIOS settings are incorrect. The computer is looking for OS files in the wrong place.
BIOS setup
The BIOS or "Basic Input/Output System" is activated when the PC is turned on. It controls the download process. It indicates from which media the OS will be launched. And if a drive is selected that does not have system files, an error will appear. Here's what you need to do to configure the BIOS:
- Immediately after turning on the computer, press Delete, F1, F2, F11, or Esc. The key depends on the model of the motherboard. When the PC starts up, an inscription will appear at the bottom of the display indicating which button is needed. The message will look something like this: "Press [key] to enter setup".
- The BIOS menu will be displayed. You can “move” along it using the arrows on the keyboard, open sections with the Enter button, return to the previous menu with the Esc button. At the bottom of the monitor, the keys needed to interact with the graphical interface in the menu should be indicated.
- Go to the "Boot" tab and enter "Boot Device Priority". This is "boot priority".
- In the first place should be the hard drive. It is usually labeled as HDD, SDD or Hard Drive. If the operating system is on another media, make it the first one.
- Return to the main menu, go to "Exit" and select "Exit Saving Changes". Or press F10.
- Try restarting your computer.
If you made any changes to the system or "overclocked" the PC, this could affect the BIOS. To return the default settings, 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 error "DISK BOOT FAILURE", what should I 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 the computer and do not know where to connect this or that device, it is better to contact the service center. Although on the motherboard all the slots are different sizes. It is impossible to attach an unsuitable part to them.
Turn off your PC before doing anything. Don't just shut down, unplug the power cord.
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, whether the OS boots from it. If it works, then the drive is working. Save your personal data 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 reconnect it.
- Attach it to another SATA connector.
- Remove the CMOS memory power supply (similar to a coin cell battery), wait 30 minutes and replace it.
- 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 if the hard drive is displayed 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 appeared due to the power supply, it must be changed. When it is discharged, 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 that part of the hard drive that contains important information for the OS is not available. In such a case, you need to restore system data. They will be written to healthy sectors.
You need an installation CD or other media with the OS (Windows will be used as an example). If you don't have it, you won't be able to reinstall the files. Because there is nowhere to get them.
- In the BIOS, set the priority so that the system starts from the boot disk.
- Insert the drive with the OS into the desired drive.
- After turning it on, you will be able to select the option "System Restore".
- Click "Startup Repair" and confirm the action. The OS itself will find problems and automatically solve them.
- If it doesn't help, start the boot disk again. Only now select "Command Prompt".
- A window will open with a black background and white text. Type in "Bootrec.exe /FixMbr" without the quotes and press Enter. The customizer reanimates the master boot records.
- You can also enter the command "Bootrec.exe /RebuildBcd". All hard drives will be scanned for OS.
If none of the above methods helped, then the hard drive is broken, the motherboard or power supply has become unusable. Also, the problem may be in a low-quality cable or slot for connection. Repairing them on your own is quite difficult. This requires professional knowledge and skills. It is better to entrust the repair to specialists. Or buy new parts.
This fault often appears if the boot order is changed or the BIOS is configured incorrectly. In this case, you can fix the failure yourself. If the problem arose due to a hardware problem, it will not be so easy to solve it.

Hello everyone In this short note, I will tell you what the Boot folder is on the system drive and whether it can be deleted. I hasten to tell you right away that you cannot delete it. Don't even think about deleting it.
To begin with, I have Windows 7 and there is a folder, but in Windows 10 I don’t see such a folder anymore, probably it shouldn’t be there.
It often happens that the user says that the computer has stopped starting. But he didn't do anything. In general, it is worth looking at the C:\ drive, and there is no Boot folder there, but the user says that he did not delete or touch anything. Well, maybe it's really not him, but some kind of virus ... although I have not seen such viruses, which had the task of simply killing Windows.
The C:\Boot folder stores data for booting Windows, so if you delete it, then Windows will just crash and you won't boot it again. I'll have to reinstall it, well, or somehow restore it, I don't even know how.
Briefly, then:
- in no case should you delete the Boot folder, it’s not just that it was made hidden;
- this folder is directly involved in the Windows boot process, for which information is needed about where the system is, on which partition and other service information;
- in addition to downloading, there is also a component for checking memory in the Boot folder;
- the Boot folder can be on the C:\ drive, and on the other, it depends on which drive the bootloader status is assigned to;
To be honest, I haven’t seen it before, but all because I’m a decent user and just don’t turn on the option to display hidden files
But when I turned it on, I saw several folders, including Boot.
Here is that folder:
The folder weighs a little:
And here's what's inside it:
You see, there are many folders there, each folder stores the language for the interface of the recovery process, well, something like this
Then there are still a couple of BCD files, BOOTSTAT.DAT and the memtest.exe executable file, this is not just a file, but a very important utility - you just can’t run it because it doesn’t work in normal mode. This is only to run in emergency cases. This utility tests the RAM for broken cells, although, to be honest, I have not yet seen a non-working RAM. No, I know that it can be like that, but in my experience not a single bar has broken yet.
If you suspect that viruses have got into the system (for example, if the Boot folder weighs a lot), then I would recommend that you check your computer for viruses. Here are the utilities I recommend for this:
- - a good tool for removing adware viruses, it works clearly and quickly, it checks all system areas and even services;
- - also an advanced utility for finding advertising viruses, can analyze the contents of browser folders, check extensions in browsers;
- - a well-known scanner, finds common, but more dangerous viruses, trojans, worms, rootkits, and other dangerous nonsense;
In general, I hope that I normally explained to you what kind of Boot folder is on the system drive and that you should never delete it
