A frequent problem is, and it flaunts "Reboot and select proper boot device or insert boot media". For those who are not fluent in English, the message can seem intimidating. In fact, everything is not so bad and with the right tactics, in most cases, the error can be easily eliminated on our own.
How are errors "Select proper Boot device" and the like translated?
Seeing this message on the screen for the first time, I want to find out what the computer means by this inscription. It's simple: the translation of "Reboot and device or Insert Boot Media" sounds like this: "Reboot and select the correct boot device or insert a bootable media." Despite the lengthy wording, problems of this nature can be solved quite simply. But the text can change.
Don't be alarmed if you see “reboot and select boot device proper”. In Russian, everything is simple: you need to restart your computer and select the correct device to boot. It may be written like this: "no bootable device hit any key", this indicates that no bootable device was found and you need to press a key (meaning any button on the keyboard). From the same category, the error "reboot and select proper boot", which calls for restarting the computer and choosing the correct device to boot it.
A slightly different meaning lies in the inscription "start booting from usb device", which informs about the need to start booting from a USB device.
Common problems causing errors
There are a number of reasons why an error occurred while starting the computer. If it says something like "no bootable", or "no bootable ..." then here are the most likely reasons for this:
- The hard drive is not working. Going into the BIOS, it is easy to determine. Then the hard disk (aka HDD) will not be detected in the "StandartCMOS Features" menu.
- Due to some failures, the DVD drive or flash card has become the primary boot device and is now in the computer.
- The operating system loader is damaged. This is usually due to a virus infection, or a sudden power outage during the operation of the computer, in case the computer was turned off improperly, as well as due to the installation of a new OS or inept actions of an inexperienced user associated with the hard drive.
These problems can be easily solved on their own. There are also more serious problems, including mechanical damage to the HDD. A symptom indicating this problem may be a strange sound that comes from
Hello! Today I rested all day, Sunday same. But in the late afternoon I thought that I needed something useful to write to my blog. I began to think what I hadn’t written yet, and what could be useful to you in the process of solving various computer breakdowns, and then the thought came that I had already written about that, and how I also wrote in it, but there is also a way by which, when turned on computer can select device to download without having to enter the BIOS. I will write about this, I am sure that this advice will be useful to many.
It is often necessary to choose from which device you need to start the computer. For example, you want, or just boot your computer from the boot disk to scan your computer for viruses. And to do this, you have to go into the BIOS, look for where this item is located in which the boot order is set, and on different computers, this is all done in different ways, and many at this stage abandon the idea of repairing the computer on their own.
If, for example, you need to boot from a CD / DVD disc or a flash drive once, then you can do without changing the settings in the BIOS. And now I will tell you how to do it.Selecting the boot device when turning on the computer
We insert the disc into the drive, or connect the USB flash drive. We reboot the computer and as soon as it starts to boot, press the key F11.
A window will appear "Please select boot device:", in which using the up and down arrows, we select the device we need from which we want to boot, and confirm our choice by pressing "Enter". As you can see, I have the ability to boot from a drive, a USB flash drive and of course a hard drive.
Which device you choose, from this one the download will go. As you can see, everything is much easier than digging into the BIOS settings. If nothing happens when you press F11, then there are at least two options:
- You have a USB keyboard, and the BIOS settings have disabled support for such keyboards when the computer starts up. You need to connect a regular keyboard, and already with its help go to BIOS and in the Integrated Peripherals item find USB Keybord support and set the Enable value. After that, your USB keyboard should work.
- And the second case, it's just that you have a different key installed to call up the boot device selection menu when you turn on the computer, or simply this function is disabled in the same BIOS. For example, in Acer laptops in the BIOS there is an item “F12 select boot device” (or something like that), which must be enabled by setting Enable. After that, the menu will be called by the F12 key.
It seems that he wrote everything, there will be questions, ask. Good luck!
The appearance of a message on the monitor screen, containing the inscription Reboot and select proper boot device, is fundamentally perplexing for many users. The operating system cannot be started. But why? Next, we propose to consider the essence of this computer failure and apply a few simple solutions to fix it. But to use them, initially at least approximately you need to know what actually caused such an impartial failure.
Reboot and select proper boot error?
Actually, the very nature of the error must be considered from the point of view of a purely technical translation of the message that appears.
In this case, it offers to restart the computer and select the correct boot device. In general, the appearance of such a message indicates that it is impossible to start the OS from the hard disk. By the way, the second line in the message prompts you to insert the bootable media and start from it. It should be understood that there are many interesting tools on the recovery discs that allow you to fix such problems (for example, the command line as well). But first things first.
Possible causes of the error
But why does a situation arise when a notification is issued with the text Reboot and select proper boot device? In the simplest and completely banal case, this can only be due to what the user installed for the removable device, and upon restarting, he simply forgot to remove it from the drive or port. But this is not the only problem.
Among the most common reasons for the appearance of the inscription Reboot and select proper boot device are the following:
- lost settings of the primary system (BIOS / UEFI);
- errors or damage to the hard drive;
- disruption of the system bootloader;
- penetration of viruses into the system;
- malfunctions of the power supply, etc.
BIOS settings and system boot options
The first step is to check the BIOS settings. In this case, the question of restoring the system boot after checking the installed components is to specify the hard drive as the first device.
This is done in the Boot section, where a line is selected that contains in the description something like Boot device priority or Boot sequence. Here you just need to put the hard drive in the first place or use the PageUp / PageDown selection keys on the first line. It goes without saying that after that the set parameters must be saved (F10 + Y).
However, even after that, the new parameters can, as they say, "fly off". On stationary computers, when booting, the line Reboot and select proper boot device appears again. Why?
The point may be that the CMOS battery has expired, which is located on the motherboard and is responsible for storing the set BIOS parameters when the terminal is turned off. Conclusion: the battery just needs to be replaced. Indirectly, the reason may be damage to the power supply or power surges. Here you will either have to try to replace the unit, or install an additional voltage regulator.
A laptop Reboot and select proper boot device may give out for a completely different reason. Very often this is due to the presence of the primary UEFI system, and not the BIOS, when the user simply does not have time to apply the keyboard shortcut to enter the settings interface. You will have to try to press the desired combination in time, but sometimes the inscription disappears, after which you can log in to the system, use the power settings and uncheck the box from the fast boot point.
The system writes "Reboot and select proper boot device": hard drive performance issues
In some cases, when starting the boot, you can use the F9 or F10 keys, which help bring up the boot menu and select the desired disk or device. But this method is fine for a one-time start. But if the problem lies precisely in the hard disk, and the line Reboot and select proper boot device appears constantly, you will have to take drastic measures.
Disk errors are not the worst thing. You can check the hard drive and fix its condition from the command line when starting from the recovery disk (chkdsk / r / f / x /). But what if the failures are not software, but physical in nature?
We'll have to make a check taking into account the surface testing. One of the good tools for this is the Hiren’s Boot CD disk utility. Also, a console program can be used for checking, but its use can be justified only in the case when the hard drive starts to "crumble". But the first utility fixes bad clusters and sectors instantly.
Bootloader damage
Finally, another problem may be that the hard disk contains damage to the boot area and the boot tool itself.
Here you need to use the command line again when starting from removable media (it is usually called through the Shift + F10 combination).
The three commands shown in the image above are used to restore. The first two are entered without fail, the third - if they did not give the desired result when the computer system was restarted.
A situation with a malfunction of the bootloader may also be associated with the impact of some types of virus threats (in this case, the appearance of the Reboot and select proper boot device start line is also possible).
But you need to deal with such things exclusively with the help of programs with the general name Rescue Disk, which are written to removable media (optical disks or USB drives), and loading is carried out from them (of course, with the installation of such devices as priority for starting in the BIOS ).
Instead of a total
In general, only the main possible reasons for the impossibility of starting the operating system were mentioned here. Unfortunately, it is impossible to tell right away what was the primary source of the failure, and what solution to apply to fix the situation. We'll have to act, as they say, at random. But, if you approach the question purely for practical reasons, you should first check the parameters of the primary system BIOS, the state of the hard disk and restore (or even overwrite) the boot record. Perhaps such actions will help.
If none of the above methods work, then you will have to change the hard drive, since critical errors may be associated solely with the fact that it began to fail. There is nothing you can do about it, and, of course, it is completely naive to hope for the use of the HDD Regenerator program. No matter how good it is, absolutely all problems with the hard drive cannot be eliminated.
After turning on the computer, the system BIOS or UEFI node is activated first, depending on the year of manufacture of the computer and its operating system.
This node starts the operating system, and if the startup process does not fail, the computer boots and operates normally.
But sometimes failures can still occur in this process, and then a typical error notification appears, one of which can be reboot and select proper boot device.

What happened?
You can understand this only if you know the essence of the processes that occur when the computer is activated.
Alternative
If the problem arose due to a violation of the sequence of execution of the BIOS boot programs, then one-time it can be eliminated in another way.
To do this, while the computer boots up, press F9 continuously (you need not to hold down and hold the button, but to do a lot of quick successive clicks).
As a result, a window will open with options for choosing a boot device.
Advice. Depending on how your computer is built, it may be necessary to use a different key for this purpose. Most often, this is F10.
In the window that opens, all the devices from which the BIOS can boot the system are listed (at the same time, some of them lack any data, but these devices are also displayed in the list).
You need to indicate from which device you need to boot the system (and for this you need to know in advance the name of your hard disk with the system) by navigating to it with the arrows.
After that press Enter and the system will boot from the specified disk without any problems.
In some cases, the problem is then eliminated and the system starts to boot normally, but more often than not, this measure is only good as a one-time measure, since it does not fix the problem and on subsequent downloads you have to repeat the same procedure.
However, it also helps in cases where there is a risk of an operating system failure requiring reinstallation, as it saves all the information you need.
Configuring UEFI
All computers had the BIOS menu before, but starting with Windows 7, all versions of the assembly of operating systems (8, 8.1, 10) are equipped with a different boot system - UEFI, with which interaction is carried out differently.
It can be more difficult to troubleshoot loading problems in it, mainly because it loads quickly enough and the user simply does not have time to do this.
Exemplary the algorithm of actions with this version of the bootloader is as follows:
- Immediately after starting the computer, start pressing F9 or F10 frequently to bring up the startup device selection menu (do it in the same way as when using BIOS);
- After you specify the drive, from which you need to boot in the same menu as when using BIOS, wait for the operating system to load and enter it;
- Click on the Start button and go to Control Panel from the menu or by typing the name after clicking the Start button;
- Go to the Power supply section;
- In the window that opens, find the line Change settings that are currently unavailable;
- Below is a list of parameters and capabilities that were not previously displayed (in the same window);
- At the very bottom of the window, find the shutdown options command block;
- It contains the option Enable fast startup (recommended);
- Uncheck the checkbox to the left of this line;
- Click on Save changes.
After that, the computer can be turned off - now it will boot more slowly, and the user can have time to go to the operating system bootloader menu.
When the operating system boots, the recommended hotkey combination will appear on the screen in order to enter the menu.
Follow the system prompts.
The menu of this loader is much more reminiscent of the interface of modern programs that are understandable to the user, therefore, it is usually easier to use it without special skills.
Go to the Boot Priority section by selecting it in the tab at the top of the window.
At the bottom of the window that opens, there are icons with a symbolic designation of boot devices.
Just place them in the desired order by dragging the icons with the mouse - put yours in the first place, the removable disk, if available, on the second, etc.
Please note that the design and layout of this menu may vary depending on the manufacturer of your device.
For this reason, the actions within the program may differ slightly.
Sometimes you have to select BIOS Features and then proceed by analogy with the algorithm described above.
Hard disk setup
In some cases, the problem really lies in the device itself from which the download is made.
In this case, the problem will not be fixed by the two previous methods.
If you apply them then the system still won't boot even from the specified drive.
This problem can arise both when using hard and.
There are many reasons for this failure.- this is physical wear and tear, and mechanical damage, and a software failure.
Malware and the accidental deletion of certain system files can sometimes cause problems.
To diagnose this component of your computer you will need a set of utilities Hiren`s Boot CD that do not require a running (booted) operating system to run.
To diagnose the device in such a way, do the following:
1 Install the media containing the Hiren`s Boot CD utilities into the drive or port, which you can download from the link http://www.softportal.com/get-22023-hirens-bootcd.html from another computer;
2 Now turn on the computer and bring up the boot device selection menu in the same way as described above;
3 A window for managing the utilities will open. DOS-style;
4 Use the arrows to navigate to the section DOS programs;
5 From there, also using the arrows - to the Hard disks section;
7 Use the arrows to navigate to the drive you want to check (bootable);
8 Walk Drive level test menu à Check and Repair bad sectors;
10 After the end of the test, the bar at the bottom of the program window may turn out to be completely blue or have red sectors, if it is completely blue, then the disk is completely healthy;
11 The presence of red sectors indicates that it needs to be restored to boot the system;
12 During the check, this system, if possible, restores and in which there are failures, but if it is impossible to do this with the resources of the utility, then the sector is indicated in red on the graphical display.
If there are red sectors, the system will not boot - the hard drive is defective and needs to be replaced. You can check this in an easier way using an emergency boot disk. If the system started from it, then the problem is not in the hard disk.
Malware action
Quite often, the cause of such failures is the malicious activity of a virus program.
In order to try to fix this problem, when the computer boots up, call the boot device selection menu, in the manner described above.
Select yours and start the operating system.
Important! If the problem is really in the action of malicious software, then the system should easily start in this way.
After that, open and run an operating system scan for malware in the usual way.
In this case, choose Full or Deep scan(depending on antivirus).
Fast or Express scan often cannot identify a virus acting at the level of system files of the hard disk, namely such, conceived, and cause problems when loading the operating system.
Once malware is found, it should be removed.
You cannot quarantine such a program, as it will not make sense.
Once uninstalled, the computer should restart without issue.
malfunction of the PC power supply. Typically, such problems are corrected by service by replacing components.
If, when you turn on the PC, you see this inscription on the screen, there may be several reasons. The message says that no boot device was found, and the user is prompted to install the required device and press a button on the keyboard. Depending on the BIOS version, the inscription may have different wording, but the meaning is always the same.
Remove the flash drive or disk
If you see this error when turning on your computer, the first step is to remove any flash drives, external hard drives, or CD from the drive. Then try rebooting your device.
This reason is explained very simply: something was changed in the BIOS settings, as a result of which the operating system tries to boot from the connected drive, which does not have boot records.
Configure BIOS
When turning on the computer, enter the BIOS by pressing the corresponding button. Depending on the BIOS manufacturer, this could be F2 or Del... In the settings you need to find the item with the name Boot sequence or . In it, in the first position you need to put a hard disk instead of a USB flash drive or CD / DVD drive. After changing the parameter, press the key F10 to save the settings and confirm the action.
Replace battery
If the changed BIOS parameters are not saved, and the next time the PC is turned on, the error repeats, the battery on the motherboard may have run out. It is very easy to change, and for this you need to remove the side cover of the system unit and find the place to install the battery. In rare cases, the reason is not in it, but in a malfunction of the power supply or strong voltage drops. The problem will be solved by replacing the power supply unit or installing a voltage stabilizer.
Reinstall Windows
In some cases, the Reboot and Select proper Boot device error appears on the monitor screen when files on the boot disk are damaged by viruses. Reinstalling the operating system will fix the problem, but it is recommended that you immediately install an antivirus program and check your hard drive.
