Are you getting- “Windows NT could not start because the following file is missing or corrupt \SYSTEM32\NTOSKRNL.EXE” error while booting up your Windows computer? Is your system unbootable and you are unable to access hard drive partitions and stored data? This behavior is caused by corrupted boot sector of Windows computer. It leads to critical situations of partition loss and you need Windows Partition Recovery to retrieve lost Windows hard drive partitions.

For a Windows computer to boot up properly, the below conditions must be true:

*

MBR (Master Boot Record) exists and it is safe.
*

Partition table is intact and it contains leastwise one active partition.

If the above conditions are fulfilled, executable code in master boot record selects the active partitions and then passes the control there, so that it can load appropriate files (NTLDR or COMMAND.COM) depending upon the file system.

However, if any of the boot file or MBR itself is either missing or corrupt, the system becomes unbootable. At this point of time, Partition Recovery becomes need of hour to work around the problem.

Sometimes, when you initiate the emergency repair process of Windows computer, the below error message occurs before the repair disk recovers any data:

“Setup has determined that your file system is corrupt”

If you boot up your system using the boot disk of the operating system and use fdisk /MBR command through Windows Recovery Console, recovery process fails.

Furthermore, if any of the NTFS file system partitions is indicating as UNKNOWN in the Disk Administrator and partition is not the part of any Fault Tolerant (FT) sets. This also can be resulted by the damaged boot sector of NTFS file system partition.

Resolution

As stated in the above error message, if the problem is caused by a damaged file system, you can try fixing it through ChkDsk command-line utility. However, if the problem is caused by damaged boot sector, hard drive formatting and operating system reinstallation is required.

Hard drive formating is able to sort out most of the hard drive related problems, but it also removes all the hard drive partitions and stored data. In such cases, Partition Recovery Software are required to handle the situation.

The Windows Partition Recovery utilities are capable of performing absolute recovery in all cases of partition loss. They are quite easy and safe to use. sante.

The next time, when it tries to open the password-protected PST, it cannot recall the password. As a result, all the e-mails and other PST items remain inaccessible to the user.

Solution

Following are the standard steps, if applied in sequence, can help a user to recover lost or forgotten PST password:

Step 1: Take your time and try to recollect the password. Most of the users keep a definite set of passwords for their files. Try to unlock the file using the most frequent passwords you use.

Step 2: Download and install pst19upg.exe utility from the Internet and use it to upgrade your PST. Ideally, this is a Microsoft provided program to update the file but the resultant file it generates is free from password protection.

Step 3: Use a third-party application to recover Lost PST Password. These Password Recovery utilities provide an easily operable interface. Such software usually generate a series of PST usable passwords. sfp2007.

Enforcing PST (Personal Storage File) password protection conforms to prevention against prying eyes that may otherwise harm the privacy of important e-mails stored in the file. By far, it is the most reliable method to preclude the undesired and unauthorized access. But as happens to all, a PST owner can lose or forget the password and lose the ability to open or access e-mails from the file. For any user with important data in such files, the experience can turn to be more upsetting if it finds no suitable backup to restore. To help users in such situations, there are various PST Password Recocvery applications.

Let’s take an example to clarify such problems and steps to recover the lost PST password. A user configures Microsoft Outlook to receive all e-mails of business use. As a result, the PST file piles up with some of very important and confidential e-mails that should not be disclosed. Thus to add a safety net, the user applies a complex password and doesn’t save it in password list. Also, it doesn’t save this password anywhere on paper or in any file.

How to Rebuild the VBR?

Go through the underwritten steps to rebuild VBR:

*

Copy all data from a similar-sized or fixed sized hard drive with identical Windows operating system version. You can obtain it through two approaches – first is to install another drive in system and copy all sectors directly from healthy drive to affected one. Second option is to copy sectors from healthy drive to floppy disk and then transfer floppy disk to the system that contains affected drive.
*

Copy VBR code from the healthy drive, which is located to Cylinder 0, Head 1, and Sector 1, to same location on damaged hard drive.
*

Reboot your system.

This method works in a number of such cases, however if you are still facing the same problem, you need to format the hard disk drive, repartition it, and reinstall the operating system. This solution eventually removes all the data from your Windows hard drive, putting you in need of Windows Recovery.

The above behavior generally means that the significant data is either missing or corruption in VBR (Volume Boot Record). The volume boot record contains operating system specific information for format of the specific hard drive
partitions. If this data area is damaged, by controller failure, virus infection, improper system shutdown etc., then Windows cannot access the hard drive.

The general response of the “Missing operating system” error is – try to boot your system through a floppy disk and re-partition the hard drive (possibly using the FDISK tool). This method, thereby completely removes the probability for any sort of recovery of your precious data. You can try out the rebuilding VBR to resolve this behavior. cmveletrhy.

Consider a practical situation, where you improperly shutdown your Windows 7 based computer system. However, when you attempt to start your system, your system does not boot and only shows a black screen with an error message that the system was not properly shutdown.

Employ a third party Windows Password Recovery Software.

To modify a Windows password, Use another user with administrator rights.  Maybe the most obvious thing to do, but not everyone knows that a director user can change the passwords for all other users also.  If you still know the password for a different director user, this is the way to go.

If last idea failed to work, you can opt for another one.  The subsequent idea is all about resetting of passwords.  As agreed by Microsoft’s Window support information base, you can set a new password easily -
- If you have typed the wrong password, you may receive a message that says your user name or password is incorrect.  When this message appears click OK.
- Click Reset password, and then implement the instructions.

Windows XP and later versions also provide an alternative way for Windows Login Password recovery with the “hard reset”.  When you make a password reset disk in the past, you can use this disk to reset passwords.

I personally recommend using a third party password resetting software. This works well for non tech persons. posse.
