If the operating system does not start, you can try to restore it through the BIOS menu. In the BIOS, you can start the system recovery process using a special recovery disk or using a regular bootable media with OS.

Restoring the operating system

1 way

Insert the boot disk into the computer's optical drive. Restart your PC. On the initial system startup screen, press the DEL key, most often used to open the BIOS menu. If you couldn't open the BIOS using DEL, see the instructions for system board. So there should be information about the keys to enter different modes settings.

In the BIOS, find the 1st Boot Device parameter. Select it and press Enter. Select an optical drive from the list that appears. Exit the BIOS, making sure to save the settings first. The computer will restart. Disk in optical drive will begin to unwind. At this moment, press any key on the keyboard. The boot disk is activated. Wait for the first dialog box to appear.

Method 2

After the initial screen appears, press R. In the next window, select the operating system to restore. If there is only one, then you will see the C:\WINDOWS folder. Press the Enter key.

A line will appear. Enter fixboot in this line. Then press Enter and the Y key. Repairing the boot sector will begin operating system. Once notified that the new boot sector has been successfully created, enter the fixmbr command. Then press the Y key. A new boot entry will be created. After creating it, enter Exit in the line. The computer will reboot and start in normal mode. The system has been restored.

After completing all the steps, enter the computer’s BIOS menu again. Select the 1st Boot Device option and check HDD. If you do not do this, the computer will start more slowly if there is any media in the optical drive.

"System Restore" is a function that is built into Windows and is called using the installer. With its help, you can bring the system to the state in which it was at the time of creation of this or that "restore points".

Do "System Restore" It is impossible to do this purely through the BIOS, so you will need installation media with the version of Windows that you want to “reanimate”. It will have to be launched through the BIOS. You also need to make sure there are special "restore points", which will allow you to roll back the settings to a working state. Usually they are made by the system by default, but if none are found, then "System Restore" will become impossible.

You also need to understand that when carrying out the recovery procedure, there is a risk of losing some user files or disrupting the functionality of programs that were recently installed. In this case, everything will depend on the creation date "Restore Points" which you are using.

Method 1: Using installation media

There is nothing complicated in this method and it is universal for almost all cases. You only need the media with the Windows Installer correctly written on it.

The instructions for it look like this:

If you have Windows 7 installed, then skip step 5 from the instructions and click directly on "System Restore".

Method 2: "Safe Mode"

This method will be relevant if you do not have media with the installer of your Windows versions. Step-by-step instruction it looks like this:

It often happens that after turning on the computer, it does not load the Windows xp OS, which until recently worked “like a clock”, despite its “advanced” age. What to do in this case will be discussed in this publication.

I would like to say right away - there is no need to panic. Windows XP was developed in 2001 and during this time a lot has changed in the Internet space. The older the system, the more software errors it has and the more vulnerable it is to modern malware.

Windows xp won't load. There are two main reasons for this:

1. Problems with software. You can try to solve them by logging into safe mode and restoring the most successful configuration, “rolling back” to a checkpoint, or, as a last resort, reinstalling the system.
2. Hardware failure. This problem is harder and easier to solve at the same time. First of all, you need to check the connection of the loop and hard drive.

In any case: before drawing any conclusions, you should go into the BIOS and see if the computer sees the HDD.

1. To restart a computer.
2. After initializing the BIOS, press F2 or Del to enter.
3. Use the arrow keys on your keyboard to go to the BOOTS section.
4. Opposite the HDD item there should not be NONE, but the name of the hard drive.

Loading from the Advanced Options Menu

If the computer does not see the HDD, then you have a hardware problem. First of all, you need to check the connection between the cable and the hard drive. If the cable is in order and power is supplied to the disk, but the system does not see the disk, then the specialists of the System Technologies company will be able to install the OS as soon as possible. We are located at: Chelyabinsk, st. Kyshtymskaya, 7A.

If it turns out that the problem is software, then you should enter the menu of additional boot options by pressing the F8 key after initializing the BIOS, and select the “load last known known configuration” option. The OS will do the rest itself.

Using the distribution disk

If the OS fails to load, restoring Windows XP using a distribution disk can help. In 99% of cases, restoring the operating system is better than reinstalling, since your programs and file folders, as well as personal information will remain unchanged. To do this you need:

We recommend that when setting the date, time and some other parameters offered to you, select the “default” option. Afterwards, they can always be changed. After the procedure, it is recommended to check and install the missing drivers.

Recovery Console

Sometimes there are cases when the OS does not load at all: only the BIOS initialization procedure occurs. Most often, this happens due to the failure of the bootloader caused by viruses. Recovery windows boot loader xp you will need a distribution kit of any version of your OS on a disk or other media.

After all operations, the computer should reboot from your OS.

Rollback using a restore point

If the system boots, but does not work correctly and intermittently after unsuccessfully installed software or viruses, restoring Windows XP can be done quite simply by “rolling back” to a checkpoint.

This can be done like this:

If a serious failure occurred in Windows that blocked access to the user interface, then the only option to make the system operational again is to restore the OS through the BIOS. For this you can use:

1. Windows distribution disk;
2. A previously created backup copy of the system by the user, if available.

When a rollback through BIOS may be required

• Virus. There is malware (advanced worms or Trojans) that not only infects files, but also the recovery environment. Removing a virus initiates a rollback procedure to the point at which the OS was infected. In this case, the only correct solution is to restore the system through the BIOS;
• Damage system files and critical failure. These phenomena have one result - the OS does not load to the user interface. A disk with a distribution or recovery image and a BIOS tool come to the rescue.

Creating an image and restore point of Windows 7

Timely creation of an OS backup is the best thing a user can do to save important data on the computer.

Backup – backup information stored in the system for the purpose of its subsequent recovery through BIOS or a recovery tool.

To create a system backup in Windows 7, the system image archiving method is used. The program provides the user with the opportunity to create an exact OS image with all available data and personal settings. You can rollback Windows to this image in the event of a program or hardware failure.

Comment. You can create a recovery disk if you have Windows computer installed by the manufacturer.

Image creation algorithm:

An image with which you can roll back the system through the BIOS has been created. Errors usually do not occur at this stage, the main thing is that the device can accommodate the downloaded information.

As for the restore point, everything is a little simpler:

It is worth noting the fact that creating a checkpoint is only possible if the recovery function is activated on the PC.

Comment. On Windows 7, by default, creating rollback points is an automatic process that occurs when programs that affect basic parameters are installed on the system.

Creating a disk and a recovery point is insurance. Not all users think about the fact that something bad can happen to the OS, so no one thinks about such a tool.

Now let's talk about BIOS setup to start Windows with boot disk or flash drives.

BIOS setup

Setting up the BIOS is a mandatory procedure, without which recovery via disk is impossible.

The first step is to call up the BIOS. Each laptop model has its own key for calling the program. This can be F1, F4, F8, F9, F11, F12 and Delete. Find the required key This can be found either in a book on using a PC, or on the website of the manufacturer.

Setting up the BIOS is not difficult; to do this you need to:

Depending on the firmware, the appearance of the program may vary, but the essence of the setting is the same - put first the media from which the operating system starts loading.

There is also a so-called “omnivorous” combination. It allows you to completely forget about setting up the BIOS in the future:

• Put in first place – USB-Flash;
• For the second - CD/DVD;
• The third one is HDD.

This option is universal, but not optimal. In this case, do not forget a disk or flash drive in the drive, as this will significantly slow down the loading of even the most powerful personal computers.

Rollback Windows 7 system via BIOS

An OS rollback via BIOS is performed when the user interface is not available due to a failure or error. Rollback algorithm for both the distribution disk and the media backup copy is the same:

• We configure the BIOS as indicated in the paragraph above. We set the parameters depending on what external device was chosen to store a backup or distribution of the system;
• After completing setting the parameters, insert installation disk or an image into a computer drive. We wait for loading and select not Windows installation, and recovery as shown in the screenshot below:

BIOS is the most important component of a computer, built into motherboard, which is responsible for checking the computer’s performance, debugging, and preparing to launch the operating system. In the event of serious problems with the Windows operating system, when, for example, logging into it is impossible due to viruses, some manipulations can be performed through the BIOS, in particular, system recovery.

If we talk about the possibility of restoring the operating system through the BIOS, then this function does not exist as such. However, if you cannot log into the operating system, you can cope with the task by using special tools that will be launched through the BIOS.

Restoring the system via BIOS

In our task, we will need an installation disk or flash drive with Windows OS - using of this instrument and system restore will be performed.

1. If you already have a bootable device that will be used to perform the recovery, great. If not, you will need to create one. You can download it from the official Microsoft website using the link below. special utility, which will allow you to download the installer to your computer and then burn it to a flash drive or disk. The operation of the program is almost completely automated; on your part, you only need to specify the drive, which will be converted into a boot drive.

2. Once you have your boot device in hand, you need to connect it to your computer and then boot it up. As soon as the computer starts up, start pressing the key responsible for entering the BIOS (it is impossible to say exactly which button is used in your case, but one of the most likely ones is F1, F2 and Del).

3. After entering the BIOS, you will need to set the flash drive or disk as the main (first) boot device. By default, users boot from the hard drive on which the operating system is actually installed. We don’t want to run Windows, but our utility, so we go to the section "Advanced BIOS Features" - "First Boot Device", and then select the device: if it is a disk, select CDROM, for a flash drive you need to select USB-HDD.

4. Save changes and exit BIOS. The computer will begin to restart automatically, and after a few moments the Windows Installer window will appear on the screen. Having selected the language, in the next window click on the button "System Restore".

5. A menu with system recovery options will be displayed on the screen, in which it is worth highlighting several items:

• Startup recovery. By selecting this item, the system will begin scanning for serious errors that prevent you from logging into Windows. If errors are found as a result of scanning, the system will automatically eliminate them.
• System Restore. This item will be effective only if your computer has a saved rollback point corresponding to the period when the computer was working normally.
• Restoring the system image. This item will be useful only if, while using Windows, you created an image of the operating system, which was saved either on the computer’s hard drive or other storage medium. This point is considered the most effective, therefore, at the beginning of using your computer, having installed all the necessary software, we recommend making a complete copy of the image, after which restoring the system will be much easier and painless.

Actually, these are the options for restoring the system through the BIOS. Choose the one that suits you best, start the process and wait until the procedure is completed. If completed successfully, the computer will automatically reboot, after which Windows should boot.
