При загрузке компьютера или ноутбука некоторые пользователи могут получить сообщение об ошибке: Disk boot failure, insert system disk and press enter — происходить это может как при попытке запуска установленной системы, так и при попытке загрузки с флешки.
В этой инструкции подробно о том, что делать при ошибке Disk Boot Failure — возможных её причинах и вариантах решения.
Неправильный порядок или режим загрузки
Перевести текст ошибки «Disk boot failure, insert system disk and press enter» можно как «Ошибка загрузки с диска, вставьте системный диск и нажмите Enter». Причина — в том, что начать загрузку системы с дисков, установленных в качестве загрузочных в BIOS/UEFI не удалось, поскольку «системных» или «загрузочных» среди них не обнаружилось.
Прежде чем приступать к другим методам решения проблемы, рекомендую зайти в БИОС и изучить параметры загрузки:
- Зайдите в БИОС/UEFI, на ПК для этого обычно можно использовать клавишу Del при загрузке, на ноутбуках часто — F2, F10 или F12, но возможны и иные варианты (Как зайти в БИОС/UEFI в Windows 11, подойдет для Windows 10 и для компьютера без ОС).
- Найдите раздел управления загрузкой в БИОС, обычно он называется «Boot», «Boot Settings», «Boot Sequence».
- Проверьте, чтобы системный диск (или флешка, с которой нужно произвести загрузку) была на первом месте в списке устройств загрузки. Если требуется загрузка установленной Windows и в списке присутствует пункт «Windows Boot Manager», установите его на первое место (обычно перемещение пунктов вверх/вниз выполняется клавишами F5 и F6 соответственно).
- Если правильное устройство уже было выбрано, но загрузка не выполняется, попробуйте изменить режим загрузки (Boot Mode) — с Legacy (CSM) на UEFI или наоборот.
- Учитывайте, что при включенном режиме UEFI (при отключенной поддержке Legacy) устройства (например, флешки), не поддерживающие UEFI загрузку, отображаться в списке устройств загрузки не будут, а при включенном режиме Legacy и отключенном UEFI не будет показываться Windows Boot Manager для системы, установленной в режиме UEFI.
- После изменения настроек БИОС, сохраните их (на вкладке Exit, также обычно это можно сделать с помощью клавиши F10) и проверьте, будет ли выполняться загрузка без ошибок после перезагрузки.
- Дополнительный важный момент: если у вас вставлены какие-либо компакт-диски в оптический привод, подключены флешки или карты памяти (или USB-хабы), а загрузку нужно выполнить с локального HDD или SSD — отключите все внешние накопители перед загрузкой.
Подводя итог: при появлении ошибки «Disk boot failure, insert system disk and press enter» прежде всего проверьте порядок загрузки и попробуйте поэкспериментировать с переключением режимов загрузки UEFI и Legacy (на некоторых материнских платах выглядит как переключение между Windows и Other OS).
Проблемы с диском или его подключением
Следующая возможная причина рассматриваемой ошибки — те или иные проблемы с диском, с которого выполняется загрузка. При этом бывает, что он то появляется, то исчезает в БИОС (либо не отображается там вообще, независимо от выбранного режима загрузки). Что можно сделать в этой ситуации?
- Переподключите диск: в случае ПК лучше всего — другим SATA-кабелем и к другому разъему SATA на материнской плате.
- Если предыдущий вариант не помог, по возможности проверьте работу диска на другом компьютере.
- Если проблема появилась после того, как вы подключили новые накопители к вашему компьютеру, проверьте: сохраняется ли она, если отключить их — случается, что из-за аппаратных проблем не системных дисков (или недостатка питания для всех накопителей из-за износа блока питания), возникают проблемы с доступом и к исправному системному диску.
В некоторых случаях причина в аппаратной неисправности диска: если он отказывается читаться и на других компьютерах, не форматируется или совсем не определяется — похоже, что дело именно в этом.
Батарейка БИОС и настройки по умолчанию
Если компьютер достаточно старый, причиной ошибки может быть севшая батарейка БИОС: в этом случае ошибку обычно однократно удается исправить ручными настройками порядка загрузки, а затем она появляется вновь. Решение — замена элемента питания CR2032 (для ноутбуков потребуется приобретать специальный, с соответствующими коннекторами).
Также в некоторых случаях помогает сброс БИОС на настройки по умолчанию: обычно это можно сделать на вкладке «Exit», лучше использовать пункт для сброса на оптимизированные настройки по умолчанию (Load optimized defaults, Load fails-safe defaults), после чего перепроверить порядок загрузки и попробовать снова загрузиться с нужного диска.
Также могут быть доступны другие способы сброса настроек БИОС: перемычка/кнопка CLR CMOS на материнской плате, либо снятие батарейки на полностью обесточенном компьютере на некоторое время (15-30 минут), подробнее: Как сбросить настройки БИОС.
Повреждение файловой системы или загрузчика
В случае, если ошибка «Disk boot failure, insert system disk and press enter» возникает при загрузке системы с локального диска, при этом он виден в БИОС/UEFI, причиной может быть сбой файловой системы или повреждение загрузчика Windows. Действия в данном случае:
- Где-то на другом компьютере подготовьте загрузочную флешку Windows 11 или Windows 10 и загрузитесь с неё.
- В запустившейся программе установки нажмите клавиши Shift+F10 (Shift+Fn+f10 на некоторых ноутбуках) — это откроет командную строку.
- По порядку введите команды
diskpart list volume
- Обратите внимание на букву системного диска (она может отличаться от C при загрузке с флешки), а также на наличие тома (раздела) FAT32 (присутствует для систем, установленных в UEFI-режиме) и его номер.
- Если раздел FAT32 присутствует, введите команды (заменив N на номер этого раздела):
select volume N assign letter=Z
- Введите команду exit для выхода из diskpart.
- Используйте команду (заменив букву диска C: на фактическую букву системного раздела при необходимости):
chkdsk C: /f
- Если раздел FAT32 присутствовал, для него также выполните проверку файловой системы с помощью команды
chkdsk Z: /f
- В случае, если в отчете о проверке файловой системы дисков на ошибки вы увидели информацию о том, что они были найдены и исправлены, попробуйте перезагрузить компьютер в обычном режиме.
В ситуации, если ошибок файловой системы найдено не было, можно попробовать выполнить восстановление загрузчика Windows вручную, подробнее об этом в инструкциях:
- Восстановление загрузчика Windows 11
- Восстановление загрузчика Windows 10
Некоторые дополнительные возможные причины проблемы и варианты решения:
- Если ошибка Disk Boot Failure появляется после завершения работы при последующем включении, но исчезает при принудительном выключении долгим удержанием кнопки питания и не появляется при перезагрузке, попробуйте отключить быстрый запуск Windows и, при наличии — опцию Fast Boot в БИОС.
- Если ваш ПК или ноутбук с чистым диском (без ОС), эта ошибка — нормальное явление: просто установите операционную систему с флешки: Установка Windows 11 с флешки, Установка Windows 10 с флешки.
- При появлении ошибки после подключения системного диска с другого компьютера причина может быть в отличающемся режиме загрузки (как описано в первом разделе инструкции), в том, что загрузчик системы находится не на том же диске, где система, а в некоторых случаях (для M.2 накопителей) — в неподдерживаемом интерфейсе: например, накопитель PCI-e NVMe был установлен на компьютере, где разъем M.2 поддерживает работу только по интерфейсу SATA).
- В случае, если вы столкнулись с проблемой после установки дополнительного диска в оптибэй, причина может быть в его неправильной работе.
- Если проблема появилась после апгрейда оборудования, например, установки новых модулей памяти, проверьте, исправляет ли ошибку возврат старых комплектующих.
Надеюсь, один из предложенных вариантов поможет разобраться в причинах и исправить ситуацию. Также вы можете подробно описать проблему в комментариях ниже — я постараюсь подсказать решение.

Описание
При загрузке компьютера на черном фоне выскакивает ошибка DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER.
Данное сообщение переводится «Загрузочный диск испорчен, вставьте системный диск и нажмите Enter».
Также, сообщение может быть с другим текстом, например, No bootable device.
Причина
- В БИОС/UEFI выставлен неправильный приоритет устройств, с которых идет загрузка операционной системы.
- Поврежден загрузчик.
- Вышел из строя дисковый носитель, на котором установлен загрузчик или от него отошел кабель.
- Неисправность материнской платы.
- Неправильная настройка БИОС.
Решение
1. Проверка носителя с установленной системой
Выход из строя диска, на котором была установлена система, обязательно, приведет к вышеописанной проблеме. Проще всего, проверить носитель на исправность — запустить БИОС и посмотреть, видит ли его компьютер, например:
* здесь мы видим, что диски компьютер видит. Однако, данный метод проверки не однозначный — если диски в БИОСе есть, еще не означает, что они корректно работают. Чтобы убедиться в корректной работе носителя, его нужно вытащить из компьютера и подключить к другому компьютеру, и проверить его специальной программой, например, HD Tune или CrystalDiskInfo.
Если диск не отображается, пробуем проверить плотность крепления кабелей питания и подключения к материнской плате:
В случае использования IDE диска, перед сообщением DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER может появиться сообщение Verifying DMI Pool Data — в данном случае нужно заменить шлейф IDE, соединяющий диск с материнской платой.
Без второго компьютера, диск можно проверить с помощью режима восстановления Windows. Для этого запускаем командную строку и вводим команду chkdsk C: /r /f, где C: — имя раздела, на котором стоит система.
2. Ждем
В некоторых случаях, может помочь длительное ожидание (около 30 минут).
Включаем компьютер, ждем около 30 минут, перезагружаем.
3. Настройка порядка загрузки системы с носителей
Данная ошибка может появиться, если в компьютере используется несколько дисковых носителей или подключены внешние накопители — внешние диски, флешки, CD-ROM. Также, причиной может стать севшая батарейка для БИОС, из-за чего каждый раз после выключения компьютера сбрасываются настройки порядка загрузки.
Чтобы это проверить, пробуем отключить все устройства, кроме диска с установленной операционной системой. Если она начнет загружаться, заходим в БИОС и переходим в раздел, отвечающий за загрузку системы — как правило, это раздел «Boot»:
После этого необходимо убедиться, что:
во-первых, приоритет загрузки за дисковым носителем:
во вторых, приоритет по дискам за тем носителем, на котором установлена операционная система:
* в данном примере выставлен в приоритет загрузки с жесткого диска VMware Virtual SCSI Hard Drive.
4. Восстановление загрузчика Windows
Загружаем компьютер в режиме восстановления Windows. Выбираем восстановление из командной строки.
Вводим команды:
bootrec.exe /fixmbr
bootrec.exe /fixboot
* первая команда перезапишет MBR в первый загрузочный сектор; вторая — создаст загрузочный сектор.
Выходим их консоли командой exit и перезагружаем компьютер.
Если это не решило проблему, снова запускаем компьютер в режиме восстановления Windows и вводим команды:
bootrec.exe /scanos
bootrec.exe /rebuildbcd
* первая команда просканирует диск на наличие операционных систем; вторая запишет найденные системы в загрузку.
5. Проблемы с материнской платой
Компьютер может не видеть жесткий диск не из-за самого диска, а из-за неисправных разъемов или дорожек на материнской плате. Данную диагностику провести в домашних условиях сложно, поэтому лучше компьютер сдать на диагностику.
Если проблема подтвердиться, необходимо будет либо провести ремонт, либо заменить плату.
6. Настройка режима БИОС / UEFI
Операционная система устанавливается для определенного режима работы микропрограммы — либо БИОС, либо UEFI. Если мы установим систему, когда компьютер загружается в режиме БИОС, при переключении на UEFI мы получим ошибку загрузки. И наоборот. Данный режим может переключиться по нескольким причинам:
- Ручная настройки БИОС.
- Сброс настроек для микропрограммы.
- Села батарейка на материнской плате.
В зависимости от версии БИОС, данная настройка имеет свои названия — пробуем найти одну из них и попробовать изменить значение настройки:
- Secure Boot — режим безопасного запуска. Иногда, нужно отключить данную опцию, чтобы можно было настроить остальные.
- Launch CSM — режим совместимости с устаревшими системами.
- UEFI and Legacy / UEFI Only / Legacy Only / Legacy и UEFI Only.
Для решения проблемы можно попробовать поиграть с даными опциями. Но если это не поможет, возвращаем предыдущие значения для настроек.
7. Замена кабеля или порта
Проблема с загрузкой может возникать из-за плохого контакта жесткого диска с материнской платой. Со временем, кабель SATA может изнашиваться, пережиматься или окисляться, что приводит к проблемам с загрузкой системы.
Можно подключить диск через другой шлейф. Также попробовать использовать другой порт материнской платы. Если в корпусе используется несколько кабелей SATA, попробуйте поменять их местами.
Перед заменой убедитесь, что компьютер выключен и отключен от сети.

When starting your computer system, a ‘disk boot failure — insert system disk’ error can occur for several reasons, including either hardware or software changes. It is possible to fix the disk boot failure error by restoring the boot sector in the case of corrupt system files. If the disk is damaged, partitioning the disk and reinstalling the operating system will solve the problem.
What does the insert system disc error message mean?
If you see the error message «DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER», «No system disk», it means the computer could not find the operating system and therefore could not boot.
Below are some possible causes and solutions.
BIOS corruption
This problem can be caused by a faulty setting in your BIOS or UEFI. To resolve this, you should try the following procedure :
- Hold on the power-button for at least 5 seconds in order to power off the computer.
- Power the system back on. When the logo screen is displayed, immediately press the F2 key (or DEL key, or any key to access your specific BIOS).
- Try to navigate through the option to load the default configuration.
- Save your changes (often by pressing F10), and restart the PC.
Disc stuck in the drive
Check to see if this is the case — if so, remove the disc(s) and try again
Incorrect boot sequence
Enter the BIOS setup of your computer and edit the boot sequence so that the computer starts primarily on drive C.
New hard drive installed
If a new hard drive has been installed, this message is quite normal. Insert the installation CD for the operating system you wish to use and then restart the machine, having made sure the CD-ROM is defined in the BIOS setup as first in the boot sequence.
Hard drive unplugged
Open the system unit and check the power cable of the hard drive is properly connected.
How to check for corrupt system files?
It may be that some system files needed to boot the computer have been deleted or damaged or that the boot sector of the disc is damaged.
To find out if this is the case, start the computer with a system disk or CD-ROM installation of your operating system (via the Recovery Console), and type «Dir C:» to check if the contents of the C drive are accessible. If they are accessible, the problem comes from missing or damaged files and you need to run the command:
fdisk /mbr sys c:
Note: Before restoring the boot sector with the command fdisk / mbr, it is recommended to use an antivirus running under DOS, such as f-prot. https://support.microsoft.com/en-us/help/166454
Damaged disc
If the hard disk or a partition is damaged:
- If it is detected in the BIOS setup, there is a chance that it can be recovered
- If so, try reinstalling the system through the installation CD, in order to reformat or recover the partition using a utility

Reasons for Disk Boot Failure Windows 10
In brief, disk boot failure Windows 10 can be caused by any of the following factors:
- Incorrect BIOS boot order. This is the most possible reason for disk boot failure SSD. Usually, BIOS tries to find the boot device by the arranged boot order. And if a wrong drive is set the default boot drive, disk boot failure Windows 10 occurs.
- Faulty data cables. If the same data cable has been used for years and for multiple computers, it might be the cause arousing disk boot failure.
- Damaged hard drive. If a hard drive gets damaged due to virus attack, power outages, read/write error, then it should be checked and fixed for errors for a successful boot.
Let’s talk about how to fix that on Windows 10 one by one:
Tip: Before you take action to fix disk boot failure Windows 10, it is better to save the files in case that things may get worse. And MiniTool Partition Wizard is a great tool that can be used to help you clone the hard drive from unbootable Windows via its bootable media. Click here to get the details.
Fix #1: Remove Newly Connected Devices
We suggest you first of all removing all the hard drives newly connected, such as USB flash drives, webcam, printer and monitor. Just keep the devices required for normal system operation like the boot drive, the keyboard and the mouse. Then restart your computer and see how this works.
Fix #2: Confirm the Boot Order
You need to enter the BIOS utility and check if the primary boot option is the primary HDD. If not, change the boot order. Follow the steps below.
Step 1. Restart the PC and pay attention to the BIOS setup message like Press DEL to enter Setup. Press the key as soon as you see that message.
Step 2. When you have entered the BIOS Setup utility, view the options listed horizontally at the top of the screen and locate the option for changing boot sequence. It could be Boot, Boot Order, Boot Options, or even under Advanced Options. All BIOS utilities are not the same, but they are basically similar.
Step 3. All hardware connected to your motherboard will be listed there. Now view their sequences and make sure the drive containing the operating system ranks first or is highlighted and selected as the first boot device.
Step 4. Save the changes to BIOS utility and exit.
Step 5. Restart your PC with the new boot order and see if the “disk boot failure insert system disk and press enter” message disappears.
Tip: WHAT IF YOUR BOOT DEVICE DOES NOT APPEAR IN THE BIOS?
If your system hard disk cannot be found in the Boot Settings, then you’ve got yourself a hardware problem, at this time, check the SATA cables first.
If you have a spare SATA cable, you try to replace the one being used and see if the disk boot failure persists. In case you do not have a spare one, see if any of your other hard drives is being detected. Take out its cable and use it to replace the faulty one for a test.
And if replacing SATA cable works, you need to buy a new cable for the boot drive. But if this does not make any difference, that’s got to be painful, for your hard drive might be failing.
Step 1. Boot your computer with Windows installation media. Then at the initial Windows Setup, go through the preparatory job and choose Repair this computer link.
Step 2. Then you need to follow this path: Troubleshoot >Advanced options > Startup Repair.

Check the hard disk or SSD connections to ensure that they are properly connected and not loose.
Step 1. Power off your computer and unplug it from the power source. Open the computer case to access the internal components.
Step 2. Locate the hard disk or SSD, which is typically a rectangular-shaped device that is connected to the motherboard using a SATA cable.
Step 3. Check that the SATA cable is securely connected to both the motherboard and the hard disk or SSD.
Step 4. If the connection appears loose, gently push the cable into the socket until it clicks into place. If your hard disk or SSD is connected via an older IDE or SCSI interface, check the cable connections and ensure that the jumpers are set correctly.
Step 5. After ensuring the connections are secure, close the computer case and reconnect the power source.
Step 6. Turn on your computer and check if the hard disk or SSD is detected in the BIOS or in the operating system.
Note: If you are not comfortable with opening your computer case or making hardware changes, it is recommended to seek assistance from a qualified technician.
Fix #3: Check Boot Order in BIOS
Ensure that the boot order is correctly set in BIOS, so that the computer tries to boot from the correct device. The system disk should be the first boot device in the boot order.
Step 1. Turn on your computer and press the key to enter the BIOS setup utility. The key to press may vary depending on your computer’s manufacturer and model, but it is usually displayed on the screen during startup. Common keys include F2, Del, Esc, or F10.
Step 2. Navigate to the Boot tab using the arrow keys and press Enter to select it. You will see a list of boot devices in the Boot Priority or Boot Order section. The top device in the list is the first boot device, followed by the second, third, and so on.
Step 3. Check that the device containing your operating system, usually your hard disk or SSD, is listed as the first boot device.
Step 4. If the boot order is incorrect, use the arrow keys to highlight the device you want to move and press the + or — key to move it up or down in the list.
Once you have set the correct boot order, press F10 to save and exit the BIOS setup utility. Confirm that you want to save the changes and exit.
Your computer will now boot from the first device in the boot order, which should be the device containing your operating system.
Fix #4: Repair the Master Boot Record (MBR)
