Reboot and select proper boot device or insert boot media что делать windows 10

Картинка с сайта: hyperpc.ru

Ошибка “Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press a key” — распространённое сообщение, которое у многих вызывает негодование. Обычно пользователи сразу же пытаются перезагрузить Windows. Однако это не помогает, и ситуация повторяется вновь: сообщение всё также появляется сразу после включения ноутбука или компьютера. Эта инструкция поможет вам избавиться от этой проблемы быстро и без усилий.

Что означает эта ошибка?

Данное сообщение, если буквально перевести на русский язык, просит вас перезагрузиться и выбрать подходящее устройство загрузки. Однако простой “ребут” системы, вряд ли исправит проблему. И дело тут не в переводе.

Эти сообщения появляются на мониторе, потому что ОС не определяет либо определённые файлы загрузки, либо само устройство (бут девайс). Вследствие этого ваш компьютер попадает в цикл и не может загрузиться окончательно.

Основные причины ошибок

• Неправильно настроен BIOS;
• Поврежден загрузочный сектор (бутсектор);
• Неисправен жёсткий диск (HDD) или SSD;
• Проблемы с файловой системой;
• Вредоносная активность.

Что делать?

Общая причина практически всех подобных ошибок — последовательность загрузки в BIOS. Поэтому для начала вам требуется заставить Windows загружать устройства в правильном порядке.

Проверьте настройки BIOS

Во время того, как система в очередной раз будет загружаться, вам необходимо нажать определённую функциональную клавишу (function key): F2, F8, F10, F12 или DEL. Так вы попадёте в BIOS

Далее перейдите в Boot: вы увидите надпись “Please select boot device”, а под ней — список устройств. Убедитесь, что HDD/SSD с вашей ОС находится выше всех остальных, на первом месте. Если же нет — выберите его, нажав Enter, и перетащите на первое место с помощью клавиши ↑). Затем сохраните изменения и закройте BIOS.

Если накопитель не указан в списке устройств, добавьте его:

• Вернитесь в BIOS и войдите в меню, отвечающее за настройку загрузки (Boot Order или Boot Options);
• Выберите Add Boot Option;
• Выберите тип устройства (например, USB-накопитель);
• Введите название;
• Далее переходим в список: там уже должно отображаться новое устройство. Ставим его на первое место;
• Не забудьте сохранить изменения.

Далее компьютер автоматически перезагрузится: у многих пользователей проблема уже решается на этом этапе. Однако если при повторном входе снова будет написано “Reboot and select proper Boot device”, значит попробуйте другой метод.

Проверьте HDD или SSD

Правильная настройка БИОСа говорит о том, что источник проблемы — записывающее устройство. Следующий шаг — сделать проверку накопителя на ошибки. Для этого вам понадобится войти в WinRe — среду восстановления Windows.

Если у вас Windows 7: Если у вас Windows 8 и выше:

Выключите устройство, зажав на десять секунд кнопку питания. Затем снова включите его. Повторите эти шаги несколько раз: так вы попадёте в WinRe. Выбираем: Устранение неполадок > Дополнительные параметры > Командная строка. В ней напишите команду: chkdsk c: /r.

Если же диагностика не дала результатов, то вам следует разобрать компьютер и проверить HDD или SSD на предмет физических неисправностей . Если накопитель вышел из строя, то его замена с большой вероятностью решит проблему.

Проверьте соединения и кабели

Теперь ваша задача проверить подключенные к ПК кабели: любые их повреждения могут вызывать сбой в системе, приводя к этой ошибке. Особенно внимательно проверьте исправность SATA кабеля. Именно он соединяет накопитель и системную плату.

Картинка с сайта: hyperpc.ru

Проверьте ОС на наличие вирусов и ошибок

Любое вирусное ПО негативно влияет на системные файлы. Это прямым образом влияет на появление разнообразных ошибок, сбоев и неисправной работы. Проведите диагностику вашего компьютера в безопасном режиме с помощью либо заводской антивирусной программы, либо скачанной в Интернете утилиты.

Различные марки и модели компьютеров (особенно такие крупные, как ASUS, LENOVO, HP и т.п.) имеют свои определённые диагностические инструменты для анализа аппаратного обеспечения. Провести такие тесты также можно в безопасном режиме: возможно именно они помогут вам решить эту проблему.

Переустановите операционную систему

Последнее, что вы можете сделать для исправления ошибок устройств загрузки, — это переустановить Windows. Однако перед этим не забудьте перенести все важные файлы на другое устройство.

Заключение

Кратко обозначим ещё раз: какие шаги предпринять, если на дисплее компьютера написано “Reboot and select proper Boot device”.

• Провести правильную настройку БИОСа;
• Провести диагностику HDD/SSD;
• Дополнительно проверить SATA кабель на повреждения;
• Провести диагностику всей ОС;
• Переустановить Windows, если другие способы не помогают.

Если ничего из вышеперечисленного не помогло, то записывайтесь в сервисный центр HYPERPC, мы поможем устранить любую неисправность вашего устройства.

What is actually the problem?

If you are trying to start your computer using the main drive where Windows 10 or Windows 11 is installed and you get the “Reboot and Select Proper Boot Device” error, it means the BIOS chip on your motherboard can’t find or read the hard drive. This can happen if no operating system is found on the first boot device in the BIOS settings, or if the installed OS is corrupted to a point that it cannot be booted. This is often the case if the computer is new.

If this error pops up when you are trying to boot from a USB flash drive, it could mean the bootable USB wasn’t created properly or it’s broken. In that case, try making the bootable drive again with different software like Rufus or use another USB drive.

Use diskpart command to set the partition as active

If your primary OS drive isn’t set as active, your computer might give you the “Reboot and Select Proper Boot Device” error. Making the partition active again could fix this.

To use diskpart, access the command prompt tool through Windows recovery. Here’s what to do:

• On the error screen, hold down the power button to force shut down your PC. Start it up again. Do this three times. If Windows enters recovery mode on the third try, go to Troubleshoot > Advanced Option > Command Prompt.
• If you can’t get into recovery mode this way, you’ll need a Windows recovery or installation media. Set your BIOS to boot from it, then go to Troubleshoot > Advanced Option > Command Prompt.

In the command prompt, type these commands, hitting Enter after each:

diskpart
select disk 0
list partition
select partition 1
active

How to Quickly Fix “Reboot and Select Proper Boot Device” Error Windows 10/8/7

With knowing the exact cause for this error, you could take the corresponding measure, but it’s not easy to find the exact cause from all possible causes. Therefore, you need to do a lot of attempts.

Luckily, the following tutorial shows what attempts should be done at first. In addition, aiming at different users, it gives different solutions. All these could help you save much time.

Check Whether The Boot Drive Is Detected by BIOS or Not

If Windows asks you to insert boot device and press any key, you could check whether the boot disk or installation media is detected by BIOS, which should be the first step.

Please boot or reboot your computer and repeatedly press on F2, Del, Esc, or another required key to enter BIOS before Windows is loaded. You can find the exact key from the internet. Then, under the Main or another tab, you’ll find all devices detected by BIOS.

If the disk where you want to start Windows isn’t here, shut down your computer, reconnect the hard disk, use another cable, or connect from another SATA slot.

Or reconnect the installation media if the “Reboot and select proper boot device or insert boot media in selected boot device and press a key” error appears when you are installing Windows 10/8/7 to your ASUS, Toshiba, Acer, Gigabyte, etc. computer.

Then, you should be able to start or install Windows if it is due to faulty cable, damaged SATA slot or improper connection.

However, if the boot disk or installation media is originally here, please try our second method.

Check Boot Order in BIOS

Generally, you can find boot order or boot sequence in “Boot“, “Startup“, or similar tab:

Картинка с сайта: www.minitool.com

But sometimes, it is under “Advanced BIOS Features“:

If the disk you want to start Windows 10/8/7 from is not the first boot device, please set it as the first boot device. If the Windows installation medium does not enjoy boot priority, please set CD-ROM or removable device as the first boot device.

How to select boot device? The “↑”, “↓”, “+”, and “−” key could help change the boot order.

At last, remember to press on F10 to save changes and quit from BIOS. Then, you should be able to start or install Windows.

Trick: Before quitting from BIOS, you’d better carefully view each tab to see whether there is a signal showing you are using UEFI boot mode. The following screenshot shows it is under UEFI boot mode:

However, if it is not UEFI but Legacy, you are using Legacy BIOS boot mode. In addition, sometimes it is CMS (compatibility Support Mode), which supports both UEFI and Legacy BIOS. In addition, sometimes it is CMS (compatibility Support Mode), which supports both UEFI and Legacy BIOS.

However, if your ASUS, Toshiba, Acer, Gigabyte, etc. computer running Windows 10/8/7 still have the “Reboot and select proper boot device” error after you are setting the correct boot order or it is originally in correct boot sequence, please try doing the next attempt.

Set Correct Partition Active (Recommended for Legacy BIOS Users)

To set active partition correctly to remove “reboot and select proper boot device Windows 10/8/7”, you’d better employ MiniTool Partition Wizard, a professional partition manager instead of Diskpart, because the former tool provides friendly GUI (Graphical User Interface) while the latter is a command-based utility.

To do this work, you need to use MiniTool Partition Wizard Bootable Edition that can be got in all paid editions. Here use Pro Edition as an example and just get it from the following button.

Step 1: Download, install and register the program on another computer to get the main window below. Here, please choose Bootable Media on the top right corner.

Step 2: Choose a USB flash drive or DVD/CD disc for the bootable media creation. For more information, view the post How to Build Boot CD/DVD Discs and Boot Flash Drive with Bootable Media Builder

Картинка с сайта: www.minitool.com

Step 3: Then, start the unbootable computer from the created bootable disc to get the main interface of MiniTool Partition Wizard.

Generally, the partition storing Windows boot files should be set active, and it is always the system reserved partition. However, if you install Windows 10/8/7 to an appointed partition, there will be no system reserved partition, and your C drive should be set active.

Therefore, you need to view the status of each partition to see whether there is an active partition already. If not, select the system reserved partition or C drive and choose the Set Active feature. However, if a wrong partition is set active, you’ll need to set this wrong partition inactive at first, and then set the correct partition active.

Step 4: At last, click the Apply button to make all changes performed.

After restarting your computer such as ASUS, Acer, Gigabyte, Toshiba, etc., the issue – “reboot and select proper boot device Windows 10/8/7” could be fixed.

Rebuild MBR (Recommended for Legacy BIOS Users)

Step 1: In the main window of MiniTool Partition Wizard, please select the disk where Windows is and click the Rebuild MBR feature.

Step 2: Click Apply to make this change performed.

Картинка с сайта: www.minitool.com

Then, you should be able to start Windows. Otherwise, you’ll need to make the next reboot and select proper boot device fix.

Set BIOS to Best Defaults

Setting to Defaults usually loads default values which are optimized for performance, without risking stability. Many users gave feedback and said this helped them fixed the issue “Reboot and select proper boot device Windows 10/8/7” flawlessly.

For different types of motherboards, their names vary, which might be Get Default Values, Load Optimized Defaults, Load Optimal Defaults, etc.

If all attempts above failed to fix reboot and select proper boot device error, most probably Windows boot files or the system itself has corrupted. Then, you’ll need to fix boot or reinstall Windows, but both require Windows installation disc.

Fix Windows Boot Files

Prepare a Windows repair disc and boot the ASUS, Acer, Toshiba or Gigabyte PC from the disc. Then, go to the following interface and click Repair your computer to enter the Windows Recovery Environment.

Картинка с сайта: www.minitool.com

For Legacy BIOS users:

• Bootrec /fixmbr
• Bootrec /fixboot
• Bootrec /rebuildBCD

For UEFI users: bcdboot C:\windows

And each type should be followed by a press on the Enter key. Then, you can quit from Command Prompt to try restarting your system. If the computer says reboot and select proper device, you’ll need to reinstall Windows.
