What does reboot and select proper mean. How to fix the error "Reboot and Select proper Boot device": first aid to the computer. Damage to the Windows bootloader

Imagine that one fine day you turn on your computer, but it only boots up to halfway, and such an interesting inscription is displayed on your monitor: “ reboot and select proper boot device or insert boot media in select boot device ".

You will most likely look at this with a slightly surprised face. However, you should immediately warn you that there is simply no reason to panic. If you see a similar inscription on your monitor on a black background, this short article in the form of an instruction can help you.

If you delve into the translation of this inscription, then we are advised to reboot and decide on the correct boot device, or insert one of the boot drives into the selected device and confirm your action by pressing any button. It should be noted right away that such an error can affect not only Windows users 7, 8, but also XP.

This manual can help you figure it out. The solution to the problem can be either the simplest or a little more complicated, but our task is to acquaint you with them. In addition to the error written a little higher, there are other variants of text similar in meaning: “No bootable device - insert boot disk and press any key, No boot device available ". These errors can be reported in different ways, depending on your BIOS version.

Reasons why the error appeared

• The BIOS settings are out of order and the boot sequence is not lined up correctly.
• Various errors related to the hard drive.
• There is a virus on your computer that you must get rid of.
• The hard drive has suffered physical damage and is refusing to function properly.

The easiest and most effective way to get rid of the error

Such an error can pop up on your monitor if any flash drives are connected to your computer or laptop, as well as hard drives. In this case, you should simply disconnect these devices before the next reboot.... Your task is to forcibly remove such devices from the computer and restart the computer again. This will most likely solve your problem.

If the easiest way didn't help

As you noticed, when loading, you may be prompted to press not only the "DEL" key, but "F9". On your computer, this may be a different key, but it will be indicated next to the words: "... to Select Booting Device after POST", or with words similar in meaning.

1. We press this key. In this case, we press "F9".
2. After the appearance of the simplest menu called "Boot Menu", select "Hard Disk". This option is suitable for those who want to boot from a disk or flash drive.
3. Now we need to select the device through which we want to boot using the "Enter" key. If you are better off downloading from a connected flash drive, then among all devices it will have its own name. You can also select the "CDROM" option, and then the download will be done using the disc.

The main thing is after Windows installations return to the BIOS again to select your "Hard Disk" in the "First Boot Device" item.

The following outstanding reasons why the error is popping up

• Your motherboard in your computer has lost a working battery. She's just shrunken and needs to be replaced.
  Your computer is unplugged too often.
• You have a problem with the power grid, which causes constant power surges.
• Problems with the power supply.

  You can personally notice one of all these reasons if you are attentive to the time and date on your computer. The first symptoms that one of these breakdowns has already taken place is that your date and time are reset after each computer start-up. There is a way out - replacing the battery on your motherboard, and also try to establish a stable power supply, and return to the BIOS to fully configure the boot.

  Power surges in the electrical outlet to which the computer is connected

  So please press the key according to real situations, and you can refer to this message for help. When you restart this computer, it will work fine. This will resolve the "boot device not found" problem. If this method does not work, try the next solution.

  Solution 4: Fix the operating system

  Then during the installation process, then during the installation process, fix your operating system.

  Suggestion: Make a system backup

  If this problem is related to bad disk sectors, it is useless. This error, which reads "Restart and select the correct boot device or insert bootable media in the selected boot device" in full form, in most cases either appears out of nowhere or is caused by corruption system files, computer boot order, or faulty hardware such as a faulty or failed hard drive.

Windows bootloader damaged

In this case, a similar inscription appears "No boot device available - No bootable devices-strike F1 to retry boot, F2 for setup utility-".

Such an inscription can be formed if some malicious program has damaged your computer.... It could also be due to too frequent power outages in your home. If you do not properly shut down your computer, and also experiment with the various functions of the hard disk. In other cases, a virus program does not allow you to fully boot your computer, and requires you to transfer funds to an electronic wallet.

Likely reasons why this error appears on your monitor

The computer is turned on in a semi-automatic mode. First, a black screen appears with brief information, then the system starts to boot. The first actions of the user are usually to enter a name and password in the Windows interface, up to this point, his role is limited to monitoring the monitor. Everything changes when, instead of the system greeting, the alarm message lights up: “Reboot and select proper boot device or insert boot media in select boot device ". In this case, you will have to help the computer deal with the problem.

What does the message "Reboot and Select proper Boot device ..." mean?

Translated into Russian, the inscription may mean something like the following: "Reboot and select a working boot device or insert the bootable media into the selected boot device."

In some BIOS versions, a similar situation causes other text messages: "No bootable device - insert boot disk and press any key" or "No boot device available". Their meaning is the same.

A simple explanation of how easy and simple to restore the boot using the example of Windows XP

Scroll through the screens until you find an option to recover, repair, or restore your computer. Use the command line option, the last one. Then you can enter and execute all the commands listed above one at a time. This works in most cases where the problem is due to system corruption.

How to solve the problem

I like to go to technical questions and write technical instructions for everyone to follow. The reasons can be different, but most of the problems can be solved on your own. Therefore, there are many options to choose from. If you go to the next step, the previous one shouldn't have succeeded.

When such a message appears, user intervention is indispensable.

Speaking simple language, the computer could not fully boot itself and asks the user to change the instructions for getting started in one of the following ways:

1. Select a different (good) boot device.
2. Insert a bootable disk or other external storage(for example, a USB flash drive) to the selected boot device.

Unfortunately, you cannot ignore this message, the computer will refuse to work until the cause of the problem is eliminated.

Why did the error message appear

The BIOS stores instructions for booting the operating system, which indicate the media on which the boot files, and also marked the priority of disk devices. Therefore, the error can be the result of a problem with any of the elements of this chain.

BIOS error

1. BIOS crash due to dead battery is a common problem with older computers. Usually the battery “outlasts” the PC, since its resource lasts more than five years, and the devices are updated more often. But if the system unit continues to properly serve the owner for longer than this period, the battery is discharged, and BIOS failures begin.
2. A consequence of outside interference. Trying to customize the BIOS to suit your needs, the user could enter incorrect instructions, the execution of which led to a failure.
3. Poor power quality. Power surges can cause errors in the BIOS, and more serious consequences.

Drive problems

Basic HDD can also serve as a source of failure. Problems can also be detected with the drive itself, for example, its physical wear or damage as a result of a fall, and with key information stored on it - accidental deletion of system files, work malware... Do not forget about intermediate links: cables, adapters, cables, plugs and other little things that provide power to the drive and read information from it.

Power supply problems

A faulty or insufficiently powerful power supply can lead to a power outage of certain elements of the computer, including the disk with bootable system files.

Malware operation

Computer viruses try to get as deep as possible into the system, so their activity or the work of antivirus applications that fight them can lead to various issues, including the appearance of the error "Reboot and select proper boot device or insert boot media in select boot device".

How to solve the problem

Insofar as possible reasons there are many alarm messages, you should exclude them one by one until the true one is found. Let's start with simple steps being careful not to harm your computer.

Step 1. Checking the DVD drive and USB ports

Most computers set the priority of the drive and external device ports when determining the boot order.

This is done to make it possible to use rescue disks or flash drives in case of problems with the hard disk. The downside of this technology is boot failure, when the BIOS interprets a disk in the tray or an attached USB drive as a system one.

Therefore, we disconnect all external devices and remove the disc from the DVD drive, if it remains there, after which we try to reboot again.

Step 2. Checking BIOS power

A characteristic sign of the discharge of the element BIOS power is a regular reset of settings, including the current date and time. In addition, the parameters are guaranteed to get lost if you turn off the computer from the network for a few minutes.

If such symptoms occur, replace the battery located on the system board. This is a simple operation that requires only care and adherence to precautions, including powering off the computer.

The battery needs to be replaced with a new one.

Step 3. Checking the hardware components

To check the sufficiency of the power supply output power, turn off all additional devices connected to the computer:

• external monitor;
• flash drives;
• a printer;
• network cable and other energy consumers.

In addition, a stable mains supply must be used to provide sufficient input current. If, after all the measures taken, the computer boots successfully, you should either replace the power supply with a more powerful one, or reduce consumption by rejecting some of the external devices.

During the check, you should also pay attention to the work indicator hard disk and the sounds emitted. If the indicator does not light up, most likely the problem is hardware, that is, the power supply is out of order or the cable has come off the drive. Also, a typical sign of problems with the power supply is the regular boot of the computer only from the second or third time. If the indicator lights up, but the hard drive emits unusual sharp sounds, then, perhaps, the matter is in the breakdown of the drive. In both cases, it is better to take the computer to a workshop to check the operation of the components on the bench.

Step 4. Configuring BIOS

Wrong BIOS settings may cause the system to try to boot from the wrong media. This problem is typical for computers with more than one physical disk. Therefore, let's start the BIOS and set the correct priorities.

Step 5. Alternative choice of boot device

Some manufacturers build in the ability to call the boot device selection window using function keys... The most common options are F10, F12, less often F8 or F9. This method is also suitable if, for some reason, it was not possible to configure the BIOS according to the previously described algorithm.

Step 6. Boot from a rescue disk or USB stick

In order to check if the system hard disk with the installed operating system and the information on it, you need to boot from an external medium: an emergency disk or a USB flash drive with an installed OS.

Of course, a prerequisite for this method is the presence of such a carrier. If there is no rescue disk or flash drive, you can create them (using another, working, computer) by downloading the necessary files from the website of antivirus manufacturers, for example, Dr Web.

You can download the contents of the rescue disk directly from the DrWeb website

By connecting a USB flash drive or placing a disk in the drive tray, go into the BIOS again and set the boot sequence with the priority of the selected device. This procedure can be carried out using hot keys directly from the boot window or manually by changing the parameters in the menu. Do not forget to return the boot priority from the hard disk after the system restore is completed.

Step 7. Check the computer with an antivirus

A successful boot from the rescue drive indicates that the problem lies in the Windows hard drive. This can be a physical problem (breakdown or poor power supply) or software, for example, the result of malware.

We check the availability of the hard disk (using Explorer or another file manager find out if the system disk icon is reflected):

1. If Windows does not see the hard drive, you can remove the cover system unit and find out if the connectors have come off the drive. If everything is in place, then it's time to carry the computer to service center, since it is necessary to check the power supply and the absence of physical damage to the disk, and this requires the appropriate instruments.
2. If the disk is available, then the reason is not a physical breakdown, but a software breakdown, so you need to run an antivirus program, usually added to emergency disk... It is possible that this will be enough to solve the problem.

How to repair the Windows bootloader

BIOS recovery and hard drive access will ensure the relative performance of the computer by booting from external media. However, if damaged Windows bootloader instead of normal BIOS operation, we will be greeted with another inscription "No boot device available - No bootable devices-strike F1 to retry boot, F2 for setup utility". In an approximate translation into Russian, it means "No available boot device - No boot devices - press F1 to reboot, F2 to call the configuration utility."

If the problem persists, it remains possible to choose the option to restore the system using backup points. This method will help even if Windows is damaged by malware.

How to avoid errors

To avoid seeing a similar message on your computer screen again, you need to take some precautions:

1. Computer care. It is necessary to monitor the computer hardware, change the BIOS battery in time (especially at the first time and date failures), and avoid dropping and other physical impacts on the components. An additional warning sign of hard drive problems can be a characteristic high-pitched sound.
2. Skilled intervention. Any tampering with the BIOS or computer hardware must be supervised by a qualified technician. Connecting additional components (video cards, hard drives, drives, etc.) must be matched to the power supply output power.
3. Antivirus protection. You should protect your computer from malware using antivirus software a trusted manufacturer.
4. Reservation. It is necessary to regularly save important information to external media, as well as create backup system restore points.
5. Tools. The "emergency kit" must contain bootable media (disk or flash drive).

A black screen when you turn on your computer instead of the friendly Windows screensaver does not always mean a fatal error. First, you can try to fix the problem yourself. If the problem persists, contact the service center. Qualified specialists will definitely help you.
