If your operating system does not boot, then your main task is to identify the cause and, if possible, eliminate it. There are two possible scenarios: damage to the computer hardware and the need to replace a component, or simply a system failure, which can be solved by a simple rollback. Let's look at how to determine what caused the error, as well as how to fix the problem.
Attention!
All of the steps below are strongly recommended only if you fully understand everything stated, so as not to harm your computer.
If after turning on the computer nothing happens and you do not see the OS loading process, then most likely the problem is a malfunction of some components of the device. The first step is to check whether all computer components are connected. To do this, disconnect the computer from the network and turn off the power supply using the toggle switch on the back wall. Open the case.
Reason 1: Hard drive failure
If after performing the steps described above the problem does not go away, then proceed to checking hard drive. Very often the cause of the problem is a media failure. You can check its functionality only by connecting the component to another computer. There are three possible scenarios here.
Option 1: HDD is detected by another computer and Windows boots
Everything is fine! Your hard drive is working fine and the problem is not there.
In this case, you need to check the disk for bad sectors. You can do this using special program Crystal Disk Info. It is completely free and will help you perform a complete diagnostic of your hard drive. Run it and pay attention to points such as Remapped sectors, Unstable sectors, Uncorrectable sector errors. If at least one of these items is highlighted in yellow, then bad sectors there are and they need to be corrected.
To recover bad blocks, run "Command line" on behalf of the administrator. To do this, use the key combination Win + X open context menu and select the appropriate item.
Then enter the following command:
Click Enter. You will be prompted to perform a recovery after rebooting the system. Enter Y and press again Enter. After this, restart your computer.
Option 3: HDD is not detected by another computer
This is the worst option. In this case, you will have to purchase a new hard drive, since the old one most likely cannot be restored. But before you do anything, consult your service center. Perhaps yours hard drive you can still return it to working condition. Otherwise, they will recommend you which drive is better to take and offer replacement services.
Reason 2: Some components are not connected
If your hard drive is working properly, then check the following components:
- Hard drive power cable;
- A cable that connects the hard drive and the motherboard;
- Are the memory modules seated tightly in the connectors?
Reason 3: Motherboard failure
If the actions taken above did not have any result, then the problem is not in the cables and the hard drive, but in motherboard. It is better to entrust this problem to specialists and take the computer to a service center.
The system tries to boot, but nothing happens
If you turn on your PC and see any signs that the system is trying to boot, then this is a great sign. In this case, you can avoid costs and solve the problem yourself.
Reason 1: Error starting explorer.exe
If the system boots, but you only see a black screen and a cursor, then the problem arose when the explorer.exe process was launched, which is responsible for loading the graphical shell. Here you can either start the process manually or perform a system rollback - at your discretion.
Launch operating system V safe mode- one of the most common ways to diagnose problems. Previously, you could get into safe mode by clicking on boot, but this triggers automatic recovery. What if you need safe mode?It's still possible to boot into safe mode, but you'll have to dig into the settings to do so. Windows recovery 8. The key now launches automatic recovery, but if you click + instead when loading, it becomes possible to manually select recovery options. However, it’s even easier to hold down and select the “Restart” command in Windows itself or on the login screen.
There are several ways to get into safe mode - it all depends on whether the system boots and whether you can enter it. Let's start with the simplest.
If the login screen is available
If the boot successfully reaches the login screen, you can hold down the key and select the “Reboot” option from the shutdown menu. The Diagnostic Tools screen will appear, allowing you to enter Safe Mode. How exactly - read below.
If the system does not boot, but there is a recovery disk
If you have another computer on hand with the same version of Windows, you can create a USB recovery drive and boot the faulty PC from it to access diagnostic tools, including safe mode (more below).
If the login screen is not available
If the boot doesn't even get to the login screen, a recovery screen will usually appear automatically. If this does not happen, try holding down the key while loading and press until it boots new mode recovery. When the recovery screen appears, click the Advanced Options button.
The problem is that this screen does not always appear. Many computers, especially new ones, do not display it.
Using advanced options to boot into Safe Mode
Whichever of the described methods you use, on the recovery screen that appears, click the “Troubleshoot” button.
Now select Advanced Options.
Finally, click the Restart button.
After the reboot, by some miracle, the familiar boot options screen will appear, where you can select Safe Mode.
Launching Safe Mode directly from Windows 8
There is another way to get into safe mode, but it will only work if Windows is already loaded. Press the +[R] keys, enter the command “msconfig” (without quotes) in the window that appears and press .
In the window that opens, go to the “Boot” tab and check the “Safe Boot” checkbox.
You can also select options secure boot:
"Minimal"– normal safe mode.
"Alternate Shell"– safe mode with command line.
"Recovery Active Directory» (Active Directory repair)– safe mode for restoring a server that is a domain controller in local network.

1. Use the System Configuration tool (Msconfig.exe)

For Windows 8 and 8.1, some sites advise using the keyboard shortcut Shift + F8, which launches recovery mode, allowing you to boot into safe mode. However, the problem is that neither Shift + F8 nor just F8 often work.

The Windows 8 recovery disk or Windows 8.1 recovery disk is designed to troubleshoot problems with the operating system when the computer cannot boot. From the recovery disk, recovery tools are launched to carry out work to restore Windows functionality.
While working on a computer, sometimes problems arise due to various reasons. Malfunctions occur due to abnormal operation of equipment, software errors, and, perhaps most common reason: incorrect user actions.
If serious problems occur, the user can launch system recovery in different ways:
- Recovery system files and settings using previously created system restore points.
- Restoring your computer (Refresh) without deleting personal data.
- Removing all data and reinstalling (Reset) Windows.
These recovery options are launched directly from the operating system. If impossible Windows startup, it is possible to start recovery by booting from bootable flash drive or with DVD disc with the operating system image, and if the user does not have Windows image, then booting from the recovery disk.
An installation DVD or bootable USB flash drive with Windows 8.1 (Windows 8) can also be used as a recovery disk by entering the operating system recovery environment.
You will need a Windows 8.1 system repair disc in the following cases:
- the user does not have installation disk or a bootable USB flash drive with the Windows1 operating system (Windows 8);
- in case of a serious computer failure;
- if impossible Windows boot.
After booting from the recovery disk, using the recovery tools, the user can carry out the necessary troubleshooting work on the computer.
Creating a Windows 8.1 Recovery Disc

- Click on the "Next" button.
- The application will check your computer for connected drives. In Windows 8, it is possible to burn to a CD/DVD disc (to do this, you will need to run another application); in Windows 8.1, a recovery disk is created only on a flash drive.
- Then a window opens with available drives. Select required disk with USB drive. The size of the flash drive must be at least 256 MB, all information from USB devices will be deleted.
- Agree to delete all data from the flash drive. Transfer data (if any) from the USB device to another drive in advance.
