При загрузке windows scanning and repairing drive volume

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.

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 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.

When starting your computer, you might encounter the error message: “Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key”. This is a serious and complicated issue involving hardware problems. Here, we will explain this error in simple terms and provide solutions to fix it for both Windows 10 and Windows 11 PCs.

Understanding the problem

If you are trying to boot to your primary OS drive where your Windows 10 or Windows 11 is installed, and you see the “Reboot and Select Proper Boot Device” error, it means that your motherboard’s BIOS chip cannot detect or read the particular hard drive. This error could also indicate that the BIOS cannot detect any operating system installed on the hard drive set to be the first boot in the BIOS, particularly if you have just purchased a new computer.

If you are trying to boot from a USB flash drive, and this error occurs, it may indicate that either the bootable was not set up correctly, or the USB flash drive is simply broken. In this case, try using another software to create the bootable USB drive or a different USB pendrive.

This issue may arise during the boot process from an SSD or a traditional HDD on both desktop and laptop computers, including those from brands such as Asus, Acer, Toshiba, and Dell. It is not restricted to any specific operating system, as it affects users of Windows 11, Windows 10, or earlier versions of Windows. Furthermore, this problem is frequently encountered in PCs equipped with recently manufactured motherboards from Asrock or Gigabyte.

How to fix the “Reboot and select proper boot device” error

Here are some solutions to fix the “Reboot and select proper boot device” error that appears when you boot your Windows 10 or Windows 11 PC.

Unplug HDD cables and plug them in again

One of the most common reasons for the error to show up upon booting is that the hard drive’s SATA or power cable becomes loose or was not plugged in correctly. Re-plugging the cables should fix the issue most of the time.

Shut down your computer, remove your CPU casing cover, unplug both the SATA cable and the power cable from the HDD, and then plug them back again. This time, make sure the cables are fastened at both ends. Retry booting your Windows 10 or Windows 11 again.

Remove all USB drives and DVD

To make sure nothing is interfering with the boot-up of your Windows, remove any existing USB flash drives, DVD, or even Floppy from the PC. Then, reboot the computer and see if the “Reboot and Select Proper Boot Device” error is resolved.

Check if you have the correct boot sequence in the BIOS

If your BIOS is set to first boot a drive that’s not your primary OS drive, and the drive has no OS, it will return the “Reboot and Select Proper Boot Device” error. Therefore, make sure your computer is booting the correct OS drive. You can check the boot sequence by going to the BIOS settings on your computer.

1. Press DEL or F2 as soon as your computer starts, to boot into BIOS.
2. In the BIOS settings, look for the option usually called Boot Priority or Boot Sequence.
3. Set the First Boot to boot your primary OS hard drive.
4. Press F10 to save the configuration and reboot your computer.

HDD hardware failure

When you’re sure your BIOS is booting the correct drive, and yet the “Reboot and Select Proper Boot Device” error still appears, it may indicate that your hard disk drive has failed or is starting to fail. Try shutting down your computer and letting your HDD cool down for several hours. Then, try to boot it again.

If it doesn’t work, try to place the HDD onto another computer and see if you can read the files in it. If you can read the files, you may want to back up all your important files and data while you still can.

Use diskpart command to set the partition as active

When the primary OS drive is not set as active, your computer will return the “Reboot and Select Proper Boot Device” error. Setting the partition as active again may solve the error.

To use diskpart, you need to have access to the command prompt tool. Try the following method to boot into Windows recovery.

• While your computer is on the error screen, press and hold the power button on your computer to force shut down. Start it up again. Repeat this for 3 times. If Windows can boot into Windows Recovery on the third attempt, navigate to Troubleshoot > Advanced Option > Command Prompt.
• If the method above doesn’t work to open Windows Recovery, you will need a Windows recovery drive or a Windows installation media (DVD or bootable USB). Set your BIOS to boot the Windows recovery drive, then navigate to Troubleshoot > Advanced Option > Command Prompt.

In the command prompt, enter the following commands followed by Enter key after each line of command.

Note that the second command is assuming disk 0 is your primary OS disk. To see a list of all disks and identify the correct disk number, type “list volume” before entering the “select disk” command. Reboot your computer and verify if the problem is fixed.

diskpart
select disk 0
list partition
select partition 1
active

Run startup repair, CHKDSK and bootrec

If none of the suggested fixes above works to solve the error, you can try to run startup repair, CHKDSK, and repair the master boot record of your Windows 10 or Windows 11.

To run these tools, you have to boot into Windows Recovery. Boot into Windows Recovery as outlined above. To run startup repair, navigate to Troubleshoot > Advanced Option > Startup Repair. Follow the on-screen instructions to complete the repair.

To run CHKDSK and bootrec commands, open Command Prompt and enter the following commands followed by Enter key after each line of command (assuming C: drive is your primary Windows 10 or Windows 11 OS drive).

chkdsk c: /f
bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd
bcdboot c:\windows /s c:

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:

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

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.

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.

Then, run Command Prompt and type the following commands.

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.
