The disk that Windows refers to is locked. Bitlocker - encryption and decryption of hard drives

However, this would not be a problem if people did not forget these very installed codes. If this is your first time faced with such a situation and do not know how to remove the password from hard disk on a laptop, then this article is for you.

HDD

If you installed the code on the internal media and forgot, then you will not even be able to boot the OS installed on your PC. That is, the ability to use a laptop or computer for its intended purpose will simply be absent. In such a situation, the user can only delete the set password because there is no other way to get access to the computer.

Online service

There are several ways to remove password from hdd, and one of them is the well-known online service " BIOS Password Removal for Laptops».

In order to get rid of forgotten code by using it, you must:

Enter it incorrectly 3 times (any combination of numbers or letters).
After that, a special code should appear in the window.
We copy the received numbers.
We enter the same combination on the site, using the link provided above.

A few seconds after entering a combination of numbers in a specially designated line, you will receive a code that will help you reset the password from your drive.

It should be clarified that this program suitable for all models and manufacturers of hard drives (seagate, hitachi, toshiba, wd, etc.). Moreover, it does not matter what operating system is installed on your computer or laptop, because this service is considered universal.

BIOS

It is possible to remove the password from the hard disk in the BIOS only if the cipher was originally installed through the bios.

All you need to do is use the standard default reset option:

Thus, we have reset the password from the HDD.

Second way

The next option is a free one, specially created for a variety of operations with hard drives.

First you need to familiarize yourself with the scheme of work password protection drive:

Winchester can have high or maximum protection.
Using the MHDD application, you can set a custom protection level.
The factory-set master password can only be changed.
The use of a master password makes it possible to unlock the disk only when high level protection.
In the case of the maximum level of protection, the hard drive can be unlocked only if a custom code is set.
If the maximum security level is set and there is no user password, then the drive can be unlocked only by destroying all data using the Security Erase Unit ATA command.

Considering the above information, in order to remove the password from the hard disk, you should:

Thus, you can very quickly remove the previously entered and forgotten cipher.

The third way

Also, the HDD_PW.EXE (18KB) program will help you to remove the password from the hard disk. In order to remove the code using it, you need to do the following:

Find out the error code (when loading, press F2 and enter the wrong combination of numbers three times, after which a special code will appear on the screen)
Start MS-DOS application.
Select the name of the utility in the window that opens.
Enter the error code that you learned earlier through a space, and add 0 through a space.
By pressing "Enter", you will see several passwords, one of which will definitely work.

After entering the code, be sure to change it to a new one and write it down.

When performing such steps on a 64-bit system, you may encounter some difficulties. The system may give an error due to a mismatch of the utility. In this situation, it is necessary:

Download DOSBox, install and run.
Mount the "C" drive with the "mount c c: /" command.
After that, at startup, press "F2", type the wrong code 3 times again and do the same.

To eliminate the likelihood of such situations, it is recommended to get rid of the cipher altogether by disabling it in the PC settings. If you are in dire need of it, then it is worth writing it down in a notebook or any other place so that you do not have to reset again.

If you have Lenovo laptop and at startup the message "enter hdd password" is displayed on the screen, the method described in this video will help you:

Bitlocker is an encryption program that first appeared in Windows 7. It can be used to encrypt volumes hard drives(even system partition), USB and MicroSD flash drives. But it often happens that the user simply forgets the password for accessing the encrypted Bitlocker data. How to unlock information on an encrypted medium, read this article.

How to enable Bitlocker

Methods for decrypting data are suggested by the program itself at the stage of creating a lock:

Prepare the drive to be encrypted. Right click on it and select "Enable Bitlocker".
Choose an encryption method.
Usually, a password is set to unlock. If you have a USB smart card reader with a conventional ISO 7816 chip, you can use it to unlock.
For encryption, options are available separately, or both at once.
In the next step, the Encryption Disk Wizard offers options for backing up the recovery key. There are three of them:
When you have chosen to save the recovery key, select the part of the drive that you want to decrypt.
Before starting data encryption, a window will appear with a notification about the process. Click Start Encryption.
Wait a while for the procedure to complete.
The drive is now encrypted and will prompt for a password (or smart card) on initial connection.

Important! You can choose the encryption method. Bitlocker supports 128 and 256 bit XTS AES and AES-CBC encryption.

Changing the encryption method for your drive

In the local editor group policy(not supported by Windows 10 Home) You can select an encryption method for data drives. The default is XTS AES 128 bit for non-removable drives and AES-CBC 128 bit for removable hard drives and flash drives.

To change the encryption method:

After changing the policy, Bitlocker will be able to password-protect the new media with the selected parameters.

How to disable Bitlocker

The locking process provides two ways to further gain access to the contents of the drive: a password and binding to a smart card. If you forgot your password or lost access to the smart card (or rather did not use it at all), all that remains is to use the recovery key. When you password-protect a flash drive, it must be created, so you can find it:

Printed on a sheet of paper. Perhaps you have placed it with important documents.
In a text document (or on a USB flash drive if the system partition was encrypted). Insert USB stick into your computer and follow the instructions. If the key is stored in text file, read it on an unencrypted device.
In the accounting Microsoft records... Log into your profile on the site in the section "Bitlocker recovery keys".

After you have found the recovery key:

Right click on the locked media and select "Unlock Disk".
In the right upper corner The Bitlocker password entry window will appear. Press " Extra options».
Select "Enter Recovery Key".
Copy or rewrite the 48-digit key and click "Unlock".
After that, the data on the medium will become available for reading.

How often do serious interventions in the life of a computer or laptop go without consequences? Almost never! And one day, after demolishing and reinstalling the operating system, installing updates, or even after hacker attacks, or maybe just jokes with BIOS settings (basic system login and logout), when turned on, a picture appears on the screen asking for a password. And you forgot it, or you don't even remember what you installed. In general, now you have an urgent need to unlock HDD... We tell how to do this in Russian, without references to English-language sites, and instructions for replacing the BIOS and other feats that most ordinary mortals are not capable of.

A small digression - why this happened. After all, most users did not set any passwords, and why the hard drive is locked is not clear. The system works in such a way that when the computer is turned on, the BIOS starts checking the hardware for operability, and if everything goes well, the OS starts loading. If she doesn't like something, for example the fact that the day before you transferred the OS to an SSD or installed a new OS, or something else, then she will lock the disk herself, even if you did not ask her for such protection measures. In any case, before despairing and going to the service specialists, who can also advise you to simply change the locked disk, you must try to figure it out yourself. So, to unlock the disk, you need to remove the password first from the BIOS, and then directly from the HDD.

Removing the BIOS password in a stationary PC

There are two steps to overcome the problem. The first is by interfering with the insides of your computer. The fact is that the BIOS, so to speak geographically, is located on motherboard... All I / O system settings are recorded when the battery is running on the motherboard. Therefore, you can reset the settings by turning it off, by removing the battery for thirty seconds, or a little longer. Not for nothing did you disassemble the system analyst? Or even easier - using a special button "Clear CMOS" or a CMOS jumper, which is specially installed for this purpose on some motherboards. But if you don’t find it, remove the battery. Of course, this must be done first by turning off the computer from the network.

Removing the BIOS password in a laptop

The catch is that such a convenient mechanical method is only suitable for stationary computers... Since laptops have a system password in non-volatile memory, there is no escape jumper, and removing the battery is unlikely to reset the password. Here you will have to short-circuit the battery contacts. This is most often done with a screwdriver. (Just do not try to do this with a bare metal rod! You will become a conductor yourself.) Find the battery and the contacts coming from it, close them in the same way for half a minute, as in the case with the battery on the PC motherboard. Again, turning off the power and removing the battery from the laptop.

Removing the password from the hard disk

Now we turn to manipulations without surgical intervention - we will directly unlock the hard drive. In the window that appears for entering the password protecting the hard disk, enter the wrong password three times. After three incorrect attempts, the "Encrypt HDD Key:" code is displayed. The numbers following this inscription must be hammered into a special code calculator located at the link: BIOS Password Removal for Laptops. We hammer the issued key into the window of this resource and in response we receive the password for our laptop. The password is cleared, the hard disk is unlocked.

Locking the disk on which the windows operating system is installed

In an attempt to get some information about this situation, the author of the article came across stingy and simply copying each other messages from computer forums. A more or less truthful explanation was found on the Microsoft website (https://support.microsoft.com/ru-ru/kb/2826045/en-us), however, on English language... Its author explains the appearance of the message "the disk on which the windows system is installed is locked" by the following user actions:

An upgrade was carried out from windows 7 to windows 8;
Intel Smart Response Technology (SRT) was included to optimize computer performance when moving from a regular hard drive to an SSD;
The user tried to conduct windows recovery 8 using WinRE's built-in Refresh your PC or Reset your PC.

In such cases, a message may appear stating that the disk with the operating system installed on it is locked. In non-Russian operating systems, this message looks like “The drive where windows is installed is locked. Unlock the drive and try again. "

Causes and solutions to the problem

Microsoft support says that one of the reasons for this message is the lack of the Intel Rapid Storage Technology (Intel RST) driver required for Intel technology Smart Response. This technology will not work without it, since it relies heavily on its use. In this case, technical support gives advice if you can download windows 8, contact your PC manufacturer and get instructions on how to disable this technology.

If the opportunity to enter home screen there is no download, then it follows:

From other posts on the forums, it can be noted that the reason lies in updating the hard drive controller driver, which does not have digital signature or it fails validation in UEFI-Bios. At the same time, the UEFI security Boot function can block its launch at the hardware level and prevent the operating system from booting. This issue is resolved by disabling this function in Bios.

There are also reports that this phenomenon occurs after the next windows updates 8. A rollback is impossible due to the lack of loading the operating system. There are also tips to use the bootrec / fixboot command - some have done this to fix the problem.

There are also many other suggestions for fixing this problem, for example, on many laptops it is possible to perform recovery from the built-in Recovery partition, but there are no positive answers to this recommendation.

This theme is further evidence of the "rawness" of windows 8, which makes developers nod to manufacturers, and manufacturers to developers.

In the modern digital world, there are a lot of all kinds of operating system errors that users who live in different parts of the world encounter every day. Today we will consider one of them - an error in which the hard disk, or rather its logical partition, with the operating system is blocked.

The situation might look like this:

The user display shows blue screen death and we lose any ability to interact with the computer until the disk is unlocked. The error text says: “Restart your computer. The drive where Windows is installed is locked. Unblock it and try again. ”

The presence of malware on the computer.
Software conflicts resulting in damaged system files.
Internal hardware failure.

Unfortunately, it is difficult to name the exact reasons for the problem, but we can help you learn how to fix it on Windows 7, Windows 8, Windows 8.1, Windows 10. The manual is universal, so the instructions will be simple and understandable for users with different operating systems.

Good afternoon, dear blog readers! Today we will talk about something that is not so frequent, but important. More than once I came across such a problem as the set password on the hard drive or BIOS. Probably many do not quite understand, and perhaps I do not understand at all what I mean. I'll explain in more detail now.

BIOS password

Bios is software, located in read-only memory (ROM), engaged in self-testing devices and finding a bootloader. Naturally, the BIOS functionality is much wider than described above, but we will not dig deep, but consider directly on the topic of our article. The BIOS password is set to avoid manipulation by third parties.

How to remove password from BIOS

Installed bios password does not make it possible to get into it, and in this case there are three options for solving this situation: by removing the CMOS battery on the motherboard, rearrange the CMOS jumper (jumper) on the motherboard in the opposite direction (not provided in laptops) or simply close the jumper contacts.

AND last way remove the BIOS password using the online service BIOS Password Removal for Laptops. If you know the password and you just find it inconvenient to enter it all the time, you can turn it off by going into the settings.

HDD password

Here the purpose and function of the password is slightly different. If in the first case you simply cannot get into the BIOS, then with the set password on the HDD you will not be able to load operating system... And this is the inability to use a computer or laptop for its intended purpose.

How to remove password from HDD

If we considered three options to solve problems with the bios, then in order to remove the password from the hdd, I have only one for you, the same bourgeois online service. I have not described above how to use this site. To unlock a password that you don't remember, you need to enter it incorrectly three times (for example, 1234 or whatever). After the attempts made, a code will appear in the window, enter it on the site http://bios-pw.org/ and in response you will receive a code to reset the password from the hard drive.

How to put a password on a hard drive or BIOS

Set these passwords to protect data and from various manipulations. Each BIOS provides such a function. Current computers and laptops have a Security tab where you can set passwords. More on this in the pictures.

Setting passwords on BIOS and hard drive

Set Supervisor Password- set Administrator password
Set User Password- set User password
HDD Password- hard disk password
Password on boot serves to enable or disable the boot password.

Well that's all, my little article has come to an end. See you soon!
