BIOS - basic system I / O information, in other words - a chip that allows you to start the computer, even if there is no operating system installed on it. BIOS stores the basic configuration of the computer and allows you to change them in a special system menu. Among such configurations, there are those that are required to successfully launch the recovery of the operating system.
If the restoration of the operating system by means of the built-in programs is impossible, in the absence of the ability to start it, recovery through BIOS comes to the rescue. With this method, your main files will be saved and the computer will be able to start successfully again.
System Restore Using BIOS Settings
To start the recovery, you must have a bootable disk with a preinstalled Windows system at hand. Alternatively, you can use a boot flash drive.
Attention! System menu SETUP stores the configurations, which it is better not to change the inexperienced user. Changing the parameters if you do not know their functions can lead to improper operation of the computer and, as a result, an unrecoverable breakdown.
Step 1: Set the boot priority of devices in the BIOS
Step 2: Restore the system using the boot disk
- Startup Recovery.
If there are hardware failures or an incorrect operation of the operating system due to the action of viruses, this is a useless function. But, in the absence of the above, you can try. - System Restore.
This is the best option for us, because it uses the boot files on the recovery media. - Restore the system image.
The option is used by users who restore the system using backup.
This completes the restoration of the system with the help of BIOS. If you do not have on hand boot image operating system, unfortunately, this recovery will not work for you. In the absence of both a boot image and a restore point, you will have to reinstall the operating system. All files on the system drive, in this case they will be completely destroyed.
Note! In case of emergency, do not lose important files for you, save them on the second logical drive, separate from the system.
Never be lazy to copy the image of the operating system, at least once a month. One spent hour a month can save your valuable files and the main thing is nerves.
Hello dear readers of the blog site Not so long ago, in one of my articles I promised to tell you, how to restore the systemwindows 7
if any software faults your computer. Such a solution is the best and the most correct way in case of errors caused by errors during the installation of updates, incorrect changes in settings, and when installing either your computer or laptop. This approach can eliminate problems that slow or block the computer.
Many inexperienced users in the occurrence of this situation resort to paid services computer help, giving at the same time not small money. However, you can restore windows 7 without having spent a penny yourself.
During the procedure, you may encounter a problem with the lack of a restore point, since the protection for the disk on which the operating system was installed was disabled, and accordingly storing copies of the system parameters and previous versions files was also disabled. To further not encounter this situation I advise you to read, .
There are several ways to restore windows 7 yourself. I will try to explain them in detail and in more detail below.
Restore windows with built-in system services
In the built-in services, there are many useful utilities that make it easy to work with a computer, and also to configure and protect it. Restore the systemwindows with the help of the built-in utility it is possible only in the event that your computer is not damaged so much that the Windows does not start. If the process of starting the computer is in the normal mode, but you are sure that you need to rollback, then after loading the Windows, right click on the shortcut My computerand select item Properties. Before you will open a window of basic information about your computer, in which on the left side we select the item Protecting the system, after which an additional window will be opened Properties of the system, where you need to press the button Recovery.
Such actions will start the utility System Restore,where it is enough to press the button Further.
If you did everything according to the instructions, the result of the correct actions will be the appearance of a new window with a choice of recovery points. To display all possible points, just tick the box next to Show other recovery points.Knowing the date and time when your operating system start to act up, you can select the point formed before this event. If you have chosen the windows recovery point, select it and click the button Further.
After all the manipulations, you will see one more window in front of you, in which information on the system recovery will be provided. If you use the password to log in, then in this window it is possible to create a password reset media. Although there will be a diskette written, but as you understand, no one uses floppy disks anymore, then you can create a password reset flash drive. The name and so it is clear why it is needed.
The last thing you have to do is press the button Done, After that a message will be displayed on the screen that the restore process can not be interrupted. To continue the process, just press the button Yes.
Now it remains to wait until the process is over, after which the computer will reboot and information will appear on the screen that the windows recovery has been successful.
Restoring the system from a safe mode
There are situations when a computer displays a simple black screen instead of the usual desktop interface. In this case, it is not necessary to be upset, we will be helped . I will not describe in detail how to run this mode, since I wrote an entire article on this topic, which you can read by clicking on the link above. The essence of this method is quite understandable, but for the lazy I'll paint a little the process itself.
At the time the computer is booted, press the F8 key several times, after which a list of additional boot options appears. You can choose any mode, because for recovery it is not important. After you have selected the desired item and clicked Enter, The system must boot in safe mode with minimal settings.
Next, you need to do the same things that are described in the first method, because when you boot safe mode The system does not change the style of its work, but only disables unnecessary files. Actually, with this method, everything is clear.
System recovery via Bios
The last and most effective way to rollback is to start the recovery of windows 7 via BIOS. This method will revitalize the computer even in difficult situations, it is enough that it is turned on.
The only thing that should be at hand is the boot disk or. More details about this method I described in, but here I will try to describe this method a little. Before you start the process of restoring the system through the BIOS, insert the disk or USB flash drive into the computer. When the computer is turned on, press the Delor F12 (it all depends on the computer manufacturer and the version of the firmware), so you run Bios. After the boot, go to the menu Boot /BootDevicePriorityand choose which media the system will boot from. If you use a disc, then choose a DVD, if a USB flash drive, then a USB HDD. Save all changes and reboot the computer. In Bios, just press F10 to do this.
After the computer rebooted, the installer window should appear. Here we select the item System Restoreand click Further.If you did everything correctly, you will be prompted to select a recovery point. In my experience I want to say that it is best to choose the first successful launch. In this case, all the programs that were installed during operation on the computer will be deleted. Do not worry about the safety of personal information, it will not be affected. After the recovery point was selected, click Further, waiting for the recovery process to finish windows 7 and push the button Yes Done. Actually, the process of restoring the system through Bios is over, it will only be necessary to remove the media from the computer and change the order of the devices from which the download should be performed in the Bios settings.
So we looked at the basic ways how to restore the system of windows 7. If none of them helped you or during the process there were questions that you can not solve yourself, then be sure to ask them in the comments.
You can also see a detailed video instruction, after viewing which there should be no questions left
Many users know that the BIOS is a necessary component of each computer, with which you can install and start the operating system. From this it can be assumed that if there are serious problems with the Windows OS, then it can be restored through the BIOS.
Faced with problems in the system, many users (and even specialists) simply rearrange the operating system. Certainly, this method effective, but the most extreme, because with the problem of the computer can be much faster to cope, after trying to perform the procedure for restoring the system.
How can I restore the system via BIOS?
System recovery via BIOS is performed in the event that the operating system does not start, which means, windows tools the system can not be restored.
A few words about the regular means of system recovery. Find it you can, if you open the menu "Control Panel" section "Recovery" .
In the next window, you need to click on the button "Starting System Restore" , and then select the restore point, when problems with the computer were not observed.
Step 1: Preparing the media with the Windows distribution
In order to restore the system through the BIOS, you will definitely need installation disk with Windows. If you do not have one, on any other computer you can write a bootable USB flash drive with the Windows distribution, for example, using the UltraISO program.
Step 2: Log into the BIOS
After you have prepared a Windows disk or a bootable USB flash drive, insert the media into the computer, and then you can proceed to restore the system through the BIOS.
First we need to get into the BIOS. The BIOS is accessed at the earliest stage of computer boot by pressing a specific button.
For entering the BIOS on each computer or laptop, you can have its own key (or combination). As a rule, in most cases this is either F2, or Del.
So, turn on the computer. As soon as it starts to boot, start repeatedly and quickly press the key responsible for entering the BIOS. After a few moments, the BIOS will be displayed on your screen.
If the first time you can not log into the BIOS, try again, but using the new key.
Step 3: Set the main loader
The appearance of the BIOS will depend on its version. For example, if you have a modern UEFI BIOS, you will be met with a fairly user-friendly interface, as well as the ability to work with the keyboard and mouse.
If you have an old BIOS installed on your computer, you will have to be content with the control only using the keyboard.
In BIOS, we need to install media with the Windows distribution, which we connected to the computer before, as the main boot device. That is, at the moment the procedure is no different from if you reinstalled Windows.
In order to put a USB flash drive or disk as the main boot device, you need to find the parameter «First boot device» (in your case, the name may be slightly different, but the essence remains the same). This option is usually located in the "Boot", "Advansed Featuers", "Boot Device Configuration" or "Boot Sequence" sections.
The screenshot below uses a Windows disk, so you'll need to set the first "CDROM" item on the account. If you use a USB flash drive with a Windows distribution, select its name.
Save the changes, and then exit the BIOS (to do this, pay attention to the bottom area of the window where the names of the buttons and actions for which they respond are displayed, for example, in our case, to save the changes, you need to click on the F10 button, and to exit BIOS, press on the ESC key.
Step 4: System Restore
The computer starts the restart, and the Windows Installer interface appears on the screen. Set the language and go on.
In the next window in the bottom area, click on the button "System Restore" .
1. Restore the launch - the function will start scanning the system for errors that interfere running Windows, and in time they will be eliminated;
2. System Recovery - If there were saved points for rollback on your computer, then in this menu you can choose the right one when there were no problems when the computer was working;
3. Restore the system image - If earlier the OS image was removed from the OS, then this function will allow using it to restore Windows functionality;
4. Diagnostics windows Memory - Runs a computer memory test;
5. Command line - the terminal window is launched.
After selecting the first item, the system will scan. Be prepared for the fact that the search for errors can take quite a long time.
Once the scan is completed, you just have to click on the button "Fix and restart" , and then check the success of the recovery.
If you have saved recovery points on your computer, select the second option "System Restore" .
Next, you will be prompted to select a recovery point and begin the rollback process. The length of the system recovery will depend on how many changes in the system operation have been made since the selected point, i. If the point was created long ago, the process can drag on for several hours.
We hope that we helped you to understand how the system is recovering through the BIOS.
If in Windows there was a serious failure that blocked access to the user interface, then the only option to make the system work again is to restore the OS through the BIOS. To do this, you can use:
- Disk with Windows distribution;
- Previously created by the user backup (backup) of the system, if any.
When you may need to roll back through the BIOS
- Virus. There is malware (advanced worms or trojans) that infects not only files, but also the recovery environment. Deleting a virus initiates the rollback procedure at the time the OS is 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 up to the user interface. The help comes the disk with the distribution kit or the image for recovery and the BIOS tool.
Create an image and restore point for Windows 7
The timely creation of an OS backup is the best thing a user can do to save important data on a computer.
Backup - backup information stored in the system for the purpose of its subsequent recovery through the BIOS or a means of recovery.
To create a backup of the system in Windows 7, the system image archiving method is applied. The program allows the user to create an accurate OS image with all available data and personal settings. You can roll back Windows to this image in the event of a program or hardware failure.
Comment. You can create a recovery disc if the Windows computer installed by the manufacturer.
Algorithm for creating an image:
The image with which you can roll back the system through the BIOS is created. Errors at this stage usually do not occur, the main thing is that the device could contain the downloaded information.
As for the recovery point, then everything is a bit simpler:
It should be noted that the creation of a control point is possible only if the recovery function is activated on the PC.
Comment. On Windows 7 by default, creating points for rollback is an automatic process that occurs when programs that affect the main parameters are installed on the system.
Creation of a disk and a point for restoration - the insurance. Not all users think about the fact that something bad can happen to the OS, so no one thinks about this tool.
Now let's talk about bIOS setup to start Windows with the boot disk or a flash drive.
BIOS Setup
BIOS setup is a required procedure, without which recovery via a disk is impossible.
The first step is to call the BIOS. Each notebook model has its own key for calling the program. This can be F1, F4, F8, F9, F11, F12 and Delete. You can find the necessary key either in the book on using the PC or on the website of the manufacturer.
Configuring BIOS is not difficult, for this you need:
Depending on the firmware, the appearance of the program may be different, but the essence of the setting is the same - put the media on top of which the operating system starts to boot.
There is also a so-called "omnivorous" combination. It allows you to completely forget about the BIOS setup in the future:
- On the first place put - USB-Flash;
- On the second - CD / DVD;
- The third - HDD.
This option is universal, but not optimal. In this case, do not forget the drive drive or USB flash drive, as it will sufficiently slow down the download of even the most powerful personal computers.
Windows 7 rollback via BIOS
OS rollback via BIOS is performed when the user interface is not available due to a failure or error. The rollback algorithm for both the distribution disk and the media backup is the same:
- Configure the BIOS as described in the paragraph above. Parameters are set depending on what external device was chosen to store the backup or the distribution of the system;
- After completing the settings, insert the installation disk or image into the computer drive. Waiting for the download and choose not to windows installation, and restore, as shown in the screenshot below:
On this instruction about how to make the rollback of Windows 7 through the BIOS ends. If the computer contains important information, then the main thing to remember is one thing: always have an external media on which the image of the system is recorded. Update the copy at least once a month.
