The appearance of a message on the monitor screen,which contains the inscription Reboot and select proper boot device, many users thoroughly puzzles. The start of the operating system is not possible. But why? Next, it is proposed to consider the essence of this computer failure and apply for its correction a few simple solutions. But to use them initially, at least approximately, you need to know what actually caused such an impartial failure.
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 proposes to producerestart the computer and select the boot device correctly. In general, the appearance of such a message indicates that the OS can not be launched from the hard disk. By the way, the second line in the messages suggests inserting the bootable media and starting from it. It should be understood that there are a lot of interesting tools on the recovery discs, which allow to eliminate such problems (for example, also the command line). But first things first.
But why there is a situation when it is issuednotification with the text Reboot and select proper boot device? In the simplest and most banal case, this can be due only to the fact that the user has set the boot priority in the BIOS for a removable device, and when restarting, simply forgot to remove it from the drive or port. But only this problem is not limited.
Among the most common reasons for the appearance of the Reboot and select proper boot device are:
The first step is to check the BIOS settings.In this case, the issue 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 you selectA string containing in the description something like Boot device priority or Boot sequence. Here you just need to set the hard drive to the first place or use the selection keys PageUp / PageDown, on the first line. Needless to say, after this, the settings must be saved (F10 + Y).
However, even after this, new parameters can, as they say, "fly off". In stationary computers, the Reboot and select proper boot device line appears again on boot. Why?
The case may be that the service life has expiredbattery CMOS, which is located on the motherboard and is responsible for storing the set BIOS parameters when the terminal is off. Conclusion: the battery needs to be simply replaced. Indirectly, the reason may be damage to the power supply unit or voltage drops in the mains. There will either have to try to replace the unit, or install an additional voltage regulator.
Laptop Reboot and select proper boot devicecan give out completely for another reason. Very often this is due to the presence of the primary system UEFI, and not the BIOS, when the user simply does not have time to apply a shortcut to enter the interface settings. You'll have to try to press the right combination in time, but sometimes the inscription disappears, after which you can log in, use the power settings and uncheck the fast boot option.
In some cases, when you start the download, you canuse the F9 or F10 keys, which help to bring up the boot menu and select the desired drive or device. But this method is suitable for a one-time start. But if the problem is exactly in the hard disk, and the Reboot and select proper boot device line appears constantly, you will have to apply the cardinal measures.
Errors on the disk - this is not the worst.You can check the hard drive and fix its status from the command line when starting from the recovery disk (chkdsk / r / f / x /). But what if the failures are not of a program but of a physical nature?
It will be necessary to carry out an inspection withtesting the surface. For this, one of the good tools can be called disk utility Hiren's Boot CD. Also, the HDD Regenerator console program can be used for testing, but its use can be justified only when the hard drive starts to "pour". But the first utility fixes bad clusters and sectors immediately.
Finally, another problem can be that the hard disk has a damaged boot area and the loader itself.
Here it is necessary to use the command line again when starting from removable media (usually it is called via the combination Shift + F10).
To restore, three commands are used,shown in the image above. The first two are mandatory, the third - if they did not give the proper result when restarting the computer system.
The situation with the loader's failure maybe associated with the impact of some varieties of virus threats (in this case, the appearance of the Reboot and select proper boot device) is also possible.
But to struggle with such things it is necessary exclusivelyusing programs with the general name Rescue Disk, which are written to removable media (optical disks or USB-drives), and downloading is done from them (of course, with the installation of such devices as priority for starting in the BIOS).
In general, only the mainpossible reasons that the start of the operating system is impossible. Unfortunately, at once it is impossible to say what was the primary source of the appearance of the malfunction, and what decision to apply to correct the situation is impossible. It is necessary 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 BIOS system, 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 isit means that you have to change the hard drive, because critical errors can be related solely to the fact that it began to go out of order. There's nothing to be done, and, of course, it's completely naive to hope for the use of the HDD Regenerator program. No matter how good it may be, absolutely all problems with the hard drive can not be eliminated simply.
