Windows 10 does not start

Questions about what to do if Windows 10 does not start, constantly reboots, blue or black screen when started, reports that the computer is launched incorrectly, about Boot Failure errors - one of the most frequently asked users. In this material, the most common errors are collected, as a result of which the computer from Windows 10 does not load and ways to solve the problem.

When you correct such errors, it is always useful to remember what happened with a computer or laptop immediately before that: Windows 10 has stopped run after upgrading or installing an antivirus, possibly after updating drivers, BIOS or add devices, or after incorrect shutdown, the short-spectant laptop battery, etc. NS. All this can help more correctly determine the cause of the problem and correct it.

Attention: The actions described in some instructions can provide not only to correct Windows 10 launch errors, but in some cases, and to the fact that they will be aggravated. Get on the steps described only if they are ready for this.

"The computer is launched incorrectly" or "It seems that the Windows system boot incorrectly"

The first widespread problem when Windows 10 does not start, and instead first (but not always) reports a certain error (Critical_Process_died, for example), and then - the blue screen with the text "Computer is incorrect" and two options for action - a computer reboot or additional parameters.

Most often (with the exception of some cases, in particular, Inaccessible_Boot_Device errors) is caused by damage to system files due to their deletion, installations and detection of programs (often - antiviruses), using computer cleaning and registry software.

You can try to solve such problems by restoring damaged files and registry Windows 10. Detailed instructions: The computer is launched incorrectly in Windows 10.

The windows 10 logo appears and the computer turns off

With its reasons, the problem when Windows 10 does not start, and the computer itself turns off, sometimes after several reboots and the appearances of the OS logo, similar to the first time described and it usually occurs after unsuccessful automatic startup fix.

Unfortunately, in this situation, we cannot get into the Windows 10 Recovery Wednesday, which is on the hard disk, and therefore we need either a recovery disk, or a boot flash drive (or disk) from Windows 10 to make which you have to do on any other computer ( If you have such a drive absent).

In detail how to boot into the recovery environment using the installation disk or flash drive in the Windows 10 Recovery disk manual. After downloading in the recovery environment, we try the methods from the "Computer run incorrectly".

Boot Failure and An Operating System WASNT FOUND errors

Another frequent problem with the launch of Windows 10 is a black screen with the text of the Boot Failure error. Reboot and Select Proper Boot Device or Insert Boot Media in Selected Boot Device or An Operating System Wasn't Found. Try DisconNecting Any Drives That Don't Contain An Operating System. Press Ctrl + Alt + Del to Restart.

In both cases, if this is not the wrong order of loading devices to BIOS or UEFI and not damage to the hard disk or SSD, almost always the cause of the start-up error is a spoiled Windows loader 10. Steps to help correct this error are described in the manual: Boot Failure and An Operating System Wasn't Found in Windows 10.

Black screen when running Windows 10

The problem when Windows 10 does not start, and instead of the desktop you see the black screen, has several options:

1. When apparently (for example, on the sound of the OS greeting), in reality everything starts, but you see only a black screen. In this case, use the black screen of Windows 10.
2. When after some kind of actions with disks (with partitions on it) or incorrect shutdown, you first see the system logo first, and then the black screen immediately and nothing else happens. As a rule, the reasons for this are the same as in the case of inchescessible_boot_device, try using methods from there (the instruction indicated above).
3. Black screen, but there is a mouse pointer - try the methods from the article not loading the desktop.
4. If, after switching on, neither the Windows 10 logo does not appear even the manufacturer's logo or the manufacturer's logo, especially if you have and without this, there are problems with starting a computer from the first time, the following two instructions will be useful to you: the computer does not turn on, the monitor does not turn on. They wrote them pretty long ago, but in general they are relevant and now will help to figure out what exactly the point is (and it is most likely not in Windows).

This is still all that I managed to systematize from the most common problems for users with the launch of Windows 10 at the current time. Additionally, I recommend paying attention to the Windows 10 restore article - it may also be able to help with solving the problems described.
