Removable drives. Solving the problem of connecting a floppy disk drive to a modern computer

Whenever something goes wrong with a computer or laptop, there are a number of tools for troubleshooting that you can perform to try to eliminate the problem. In Windows 10/8/7 there are several built-in commands that can be used to check and restore damaged system files that eventually cause problems when changing. One of the ways to troubleshoot problems associated with Windows is to check the system and restore system files. It can help in all types of problems such as a slow system, blue screen Death, sudden power failures and system failures.

Consider how to run the system file verification tool in Windows using cMD command line and PowerShell, such teams as sFC / SCANNOW. and tools DISM. I want to note that to update Anniversary Update Windows 10, it will be better to use methods from PowerShell.

Check and restore system files via CMD

System file verification tool scans your computer for any damage or changes in system files that could otherwise interfere with the normal operation of your PC. From there he replaces the file proper versionto ensure uninterrupted work. Using the command line, you can try to scan and restore system files Late operating systems, like Windows 10/8/7 / Vista. We will examine two teams sFC / SCANNOW and DISM Using CMD.

1.

Launch command line (CMD) on behalf of the administrator. Click "Search" and write simply "CMD" or "Command Line", then on it right-click and launch on behalf of the admin.

Set the command sFC / SCANNOW.and wait for the end of the process.

Note:After scanning your system, one of three results will be issued:

System file errors will not be.
There will be errors of system files and Windows will restore them automatically.
Windows has detected errors, but cannot restore some of them.

If you feature option 3, that the error is detected and the system cannot recover, then do the procedure. I advise you to disable encryption and, if at the time of the check they are available. Nothing succeeded? Moving below.

2. (DISM)

If the above does not work in safe mode, there is one last method Check damage in system files and fix them. Use the Deployment Image and Service Management (DISM) tool. The command works with Windows 8 / 8.1 / 10 systems. Open back and use the following command:

The process can take a long time with the percentage of the percentage scale. Having finished working, restart the computer and run back sFC / SCANNOW, To make sure that there is no error or the error disappeared.

Check and restore system files throughPowerShell

We will use Windows PowerShell to show how to use service and management service DISM. For scanning and correcting damaged system files in Windows 10. This method will be more efficient to update Anniversary Windows 10 than the command line.

1. Using the SYSTEM FILE CHECKER (SFC) tool

Launch PowerShell On behalf of the administrator. Click "Search" and type Windows PowerShell, after right-click and select on behalf of the admin.

Set the command in the PowerShell window sFC / SCANNOW.If scan detects any problems, Windows will try to fix them. If Windows cannot fix them, he will warn you that further research and actions are needed. Move below if errors are detected.

2. Using the Deployment Image and Service Management tool (DISM)

DISM scan detects corrupted system files and Windows will try to fix them, and will give you a progress report at the end. If Windows cannot find the files needed to restore damaged system files, you will also be provided with information about what to do next, with reference to the Microsoft website and troubleshooting options. Set the command below to the PowerShell window.

DISM / ONLINE / CLEANUP-Image / RESTOREHEALTH

If DISM fixed it or did not reveal the errors, then restart the laptop, computer and run to check back sFC / SCANNOW.

Hello, friends! Systemic restoration windows files 7 or Windows 8 / 8.1 The most interesting topic. Especially if the operating system begins to bullure, and we have no recovery image and we forgot to turn on the system protection. To create a recovery point. In this case, we will not be able to restore the system from the image, we will not be able to roll back Windows to the created point of recovery and reinstall the system too lazy, as it will take a whole day. And just here we have another chance to return Windows to a normal state - try to restore system files. In this article I will try to fully disclose the topic so that you can reanimate our computer in any situation.

In the opened command line we write:

sFC / SCANNOW.

We wait a little ...

If you have a system in order, you will see the following image.

If Windows has been Paul, you will see the following.

System files have been successfully restored. Reboot and immediately turn on the system protection to create recovery points in order to just roll back the computer status a couple of days ago and that's it.

It happens that when scanning the SFC.EXE utility system has found damaged files, but it could not fix them. In this case, I would make restoring system files in safe mode. If in safe mode the same read the last article.

If it did not work out on the Recovery Wednesday by the F8 key, it will be necessary to boot from the installation (loading) flash drive or disk. How to boot from the flash drive -. In the same way, you can load boot from the disk. Only in this case you need a DVD-RW (reader for reading optical disks) Put the load in the first place in the priority.

I like to boot from removable media using the boot menu. In Asus motherboards, it is usually called also the key F8..

After booting from the flash drive or from the disk I saw the following picture. I choose Windows Setup. - Installing Windows.

We choose the one that we do not turn on. And here carefully! We remember the letter that has assisted the restoration environment of your system (in the folder column). I have it D..

We enter the command:

sFC / SCANNOW / OFFBOOTDIR \u003d D: \\ / offwindir \u003d D: \\ Windows

You can go to the disk and make sure that and where.

Use the utility Diskpart.

At the command prompt, enter:

diskpart. - Call the utility to work with discs.

lIST DISK. - We view the list of disks.

sELECT DISK. - I choose the hard drive you need.

For Windows 8 / 8.1

If the SFC utility could not recover damaged system files, then you need to try to restore the repository of these system files. The place where copies of serviceable system files should be located. As I understood, it is located at C: \\ Windows \\ WinSXS. That is, we first need to fix the file store, and after the SFC / SCANNOW command, restore Windows system files.

Storage Restore Using Windows Update

Run Windows PowerShell with administrator rights. To do this, open the Start menu or the initial screen and click on the "Search" icon. In the search box writing PowerShell. Click right-click on Windows PowerShell and select "RUN AS Administrator" or "Starting on behalf of the administrator".

In the opened window we write

DISM / ONLINE / CLEANUP-Image / RESTOREHEALTH

and wait. If the storage is an integer or managed to restore, using Windows Update, you will see the following picture.

If image Health State: Healthy - everything is fine. Reboot your computer and try again SFC / SCANNOW.

Restoration of the repository using the image

If we have problems with Windows Update, then this method will suit.

Download the original image of Windows 8 / 8.1 of the same bit as your system. How to find out the bit installed system — .

Connect or mount the downloaded image. Click on the right mouse button and select "Connect" or "Mount".

At the command prompt with administrator rights, we look at what editions in the form of a team

I have 2 editions in my image. What I need to understand on these distinctive signs. We use the first. If not go - the second.

Run Windows PowerShell with administrator rights and ask the command

Repair-WindowsImage -Source F: \\ Sources \\ Install.wim: 1

where, F - the letter of the disk to which we have connected the image, 1 is the Windows Edition Number in the image.

Restore system files manually

If using the SFC utility failed to restore broken files, you need to try to do it manually. In this case, you need to additionally run the command

findStr / C:% Windir% \\ Logs \\ CBS \\ CBS.log\u003e% UserProfile% \\ Desktop \\ sfcdetails.txt

FINDSTR / C:% WINDIR% \\ LOGS \\ CBS \\ CBS.log\u003e SFCDETAILS.TXT

and carefully examine the file sfcdetails.txt on the desktop or in % WINDIR% \\ LOGS \\ CBS \\.

There must be something similar as in the figure below.

After the name of the damaged file is known (accessibility.dll), we look for it on another computer with the same system as yours. If this is not an option, I would download the original image of Windows and installed it on the virtual machine. I found the file you need and copied to the boot or installation flash drive. Then, with this mounting flash drive, it booted into the recovery environment, would launch the command line. From the command line would opened a notebook. Opened the File\u003e Open menu - and here I have a practically a full-fledged conductor. Copy with a replacement serviceable file from a flash drive, reboot and everything should work.

If you have an option with installation virtual machine Not suitable, you can connect the install.wim file to the folder. Then go to this folder and copy the necessary files.

Create a folder. For example, "Win8.1Pro" at the root of D.

Copy the install.wim file in the root of D. D.

Mount the install.wim file in the created folder.

We go to the created folder and copy the necessary files.

Turn off the image

DISM / UNMOUNT-WIM /MOUNTDIR :D:\\Win8.1PRO / Discard

Conclusion

So I will try to restore system files in Windows 7 / 8/8.1. Questions and wishes Write in the comments. Thank you for sharing the article in social networks. Good luck to you!

Sincerely, Anton Dyachenko

The integrity of system files depends not only by the performance of Windows itself, but also programs and applications that were installed on the computer. If you encounter an error, the program does not start or brakes, it is necessary to check the system for the integrity of the files and recover them if necessary.

How to check windows 7 on the integrity of system files?

To customize Windows 7 to the integrity of system files as follows:

Click "Win + R" and enter "CMD".

The command line opens. In the console, enter "SFC / SCANNOW".

The system check will be launched, after which the state file status is submitted.

In cases where the message appears when you start the command, the Windows Protection of Windows resources failed to launch the recovery service ... ", then you should do the following:

Click "Win + R" and enter "ServiSes.msc".

The Services window opens. Here you need to find and enable "Installer windows modules».

To do this, double-click the service and set the start type "manually".

After rebooting the system and repeat the start of the command in the string.

How to recover system files in Windows 7 in various ways?

The "SFC / SCANNOW" command except the check also performs the recovery of system files. However, if it could not perform the "repair" of these files, it is worth doing the following actions:

In the command line, enter: FindstR / C: "% WINDR% \\ LOGS \\ CBS \\ CBS.log\u003e"% UserProfile% \\ Desktop \\ SFC.Txt ".

A text document "SFC" will appear on the desktop, in which the list of files will be presented, which could not be restored.

The list find damaged files and copy their versions from the working PC. After replacing damaged files, the system will work correctly.

You can also check and restore system files from the recovery environment using the MSDART tool. Initially download and write down ISO Image Recovery disk system "ERD Commander". After, booting from the installation disk or flash drive, select the corresponding item.

A new window will appear. Select "System File Check Tool".

The system file restore wizard will be launched. Follow the instructions.

We put the mark "Scan and Request Before Form".

The search for damaged files will start. After a window appears with a report, where you need to put a mark near the defective element and click "Next".

After restoring restoring PC.

Not many know that Windows system files can be checked using a special sFC / SCANNOW commands. Let's try to figure it out in which case the use of this command can be useful.

If you suspect that system files are damaged, modified or missing in WinODWS 7 and Windows 8 You can check system files using the built-in operating system.

So in order to remember the integrity of the operating system filesyou need to run the scan utility. For this.

1. Run the command line. Press the Win + R key combination, in the window that opens, type cmd.. The command line window opens. If you have Windows 8.1, then press Win + X keys and run the "Command Line (Administrator)" from the menu that will appear.

2. Enter on the command prompt SFC / SCANNOW.. The check utility will start windows systems. This utility will check the Windows files, and if possible, fixes.

There is also a very important remark!If during the verification process, the system has detected damaged files abstract on the command line:dISM / ONLINE / CLEANUP-image / RestoreHealth and wait until the missing files are loaded and installed!

Extended use of the SFC / SCANNOW utility

Full list of parametersWith which you can run this command as follows:

SFC.

What is it for?

You can start checking system files without correcting them with SFC / Verifyonly.
- It is possible to check and correct only one system file by executing the command. sFC / SCANFile \u003d Path_F_File (or VerifyFile, if not required to correct).
-The check system files not in current windows (and, for example, on another hard disk) you can use SFC / SCANNOW / OFFWINDIR \u003d Path_K_Papka_Windows

These features will be useful, for example, if you know what particular file fails, or you need to check the system on another disk.

When using the system file check utility, you may encounter some problems and errors.

For example, when you start SFC / SCANNow, you will see a message that "Windows resource protection cannot run the recovery service", check that the Windows Module Installer service is enabled, and the start type is set "manually".

If you have modified files in the system, for example, you replaced the icons in the explorer or something else, then the execution of automatic correction will return the files to the initial look. Also, the correction can be returned to the initial species modified Windows assembly.

It may turn out that SFC / SCANNOW will not be able to correct errors in system filesIn this case, you can enter on the command prompt:

fINDSTR / C: »»% WINDIR% \\ LOGS \\ CBS \\ CBS.log\u003e »% UserProfile% \\ Desktop \\ SFC.TXT»
Creating system file verification log

This command will create a text file SFC.Txton the desktop with a list of files, the correction of which failed.

If you need, you can copy required files from another computer with the same windows version or from the OS distribution. (which is more preferable).

Disabled or running applications from Windows Store, problems in the work of the desktop part of Windows and the instability of the operating system as a whole are often a consequence of damage to important system files. The easiest way out of the situation when system files are damaged - or to. But such a move requires the presence of the latter - if not in the fresh edition, then at least in some. If not even at least some recovery point or backupBefore resorting to a radical solution to a problem in the form of Windows, you can try to restore the integrity of its system files. Below will look at 5 ways how to do this, provided that the current Windows is still capable of loading. Directly the ways to restore the integrity of Windows files will be proposed only two, three others are solutions for situations complicated by the need to restore the storage of the system components.

1. Restore the integrity of Windows files

To identify missing or damaged important system files and their windows restoration Provides a regular SFC.exe utility running using the command line. The utility replaces the damaged or missing system files by their originals from a special storage of components located in the WINSXS folder inside the Windows directory on the S. disk, on behalf of the administrator, command prompt and enter:

Press ENTER. After scanning to identify the system files to be replaced, they will be restored.

But this is the successful completion of the operation. When the contents of the storage itself is damaged, the operation will be completed with the message about the impossibility of restoring some of the system files. In this case, before you need to resort to the restoration of the Windows component repository, and then the operation to restore files in their working directories.

2. Restoring system component storage: DISM

To restore the system of original system files, resort to assistance utility for service windows images - DISM, also running through the command line. In the process of restoring the warehouse, the utility will use Windows Update Service and loads missing or damaged system files from Microsoft servers. Because the presence of the Internet - required condition For a successful operation.

Run on behalf of the administrator the command line and enter:

DISM / ONLINE / CLEANUP-Image / RESTOREHEALTH

Press ENTER. With a successful attempt to carry out the operation, we will see the appropriate notification.

Now we carry out the operation considered in paragraph 1 of the article.

It may be that the process of operation will hang or fail. Notification of unsuccessful attempt The operation will, in particular, be accompanied by a proposal to specify the path from where you can take data to restore the storage of the system components.

The process of restoring the repository with an indication of the data source will look at a little later, in clause 4 of articles.

3. Restoring system components storage: PowerShell

Restore system components can alternative way - Using the Windows PowerShell tool. This method is similar to the previous one: Windows update service is also used to restore the repository. And, accordingly, in this case the Internet connection is also necessary. The method using PowerShell will take longer than the previous way with the participation of the DISM utility, but also the repository recovery process will be carried out more thoroughly.

Run on behalf of the PowerShell administrator and enter:

REPAIR-WindowsImage -Online -restoreHealth

Press ENTER. If you successfully restore the system file repository, we obtain such a report as specified in the screenshot below, where, in particular, the "Image Health State" parameter will be marked as "Healthy". And this means that the system file repository is restored. Now it is necessary to carry out the operation described in paragraph 1 of the article.

4. Restoring system components storage: Windows installation disk

To restore the storage of Windows components, with an indication of the data source, you can resort if there is no Internet or two previous methods did not bring positive results. The source from where data is retrieved to restore the system component repository - this installation disk The relevant version and edition of Windows. This can be a physical installation medium - a flash drive or disk, and may be an ISO image with a distribution. The latter needs to be installed in virtual driveby calling on it context menu and choosing the "Connect" command.

We connect a flash drive, disk or image, run on behalf of the PowerShell administrator and enter the type command:

Repair-WindowsImage -Source D: \\ Sources \\ Install.wim

In this team, the letter disc installation media Substituted. In our example, this is the letter d, and instead of it in each individual case, you need to substitute your letter of a flash drive, a physical or mounted drive, as they mean in windows Explorer. After entering the command, press ENTER.

According to the results of the operation, as in the previous case, the "HEALTHY" status of the "Image Health State" parameter will indicate the successful completion.

After restoring the repository, we launch the operation considered in paragraph 1 of the article.

5. Windows 10 update

Restore the integrity of damaged Windows 10 system files by updating the system by updating utilities Media. Creation Tool. It can be downloaded on the official website of Microsoft. Windows 10 update - the longest time, at the same time, the most reliable way to return operating system performance. The Windows 10 update process passes approximately as much as the process of its reinstallation. As part of this process, all damaged system files will be overwritten, the user profile data will be saved, software installed and submitted system settings, and at the exit we get the freshest, with all installed windows updates 10 Anniversary Update.

Run Media Creation Tool. We accept licensing conditions.

Select "update this computer now."

And wait for the completion of the update process.

Excellent day!
