What is a boot sector? All disks and hard drives are divided into small sectors. The first sector is called the boot sector and contains the Master Boot Record (MBR). The MBR contains the information concerning the location of partitions on the drive and reading of the bootable operating system partition. During the boot-up sequence on a DOS-based PC, the BIOS searches for certain system files, IO.SYS and MS-DOS.SYS. When those files have been located, the BIOS then searches for the first sector on that disk or drive and loads the needed Master Boot Record information into memory. The BIOS passes control to a program in the MBR which in turn loads IO.SYS. This latter file is responsible for loading the remainder of the operating system. What is a boot sector virus? A boot sector virus is one that infects the first sector, i.e. the boot sector, of a floppy disk or hard drive. Boot sector viruses can also infect the MBR. The first PC virus in the wild was Brain, a boot sector virus that exhibited stealth techniques to avoid detection. Brain also changed the volume label of the disk drive. How to avoid boot sector viruses. Commonly, infected floppies and subsequent boot sector infections result from “shared” diskettes and pirated software applications. It is relatively easy to avoid boot sector viruses. Most are spread when users inadvertently leave floppy disks in the drive – which happen to be infected with a boot sector virus. The next time they boot up their PC, the virus infects the local drive. Most systems allow users to change the boot sequence so that the system always attempts to boot first from the local hard drive (C:\) or CD-ROM drive. Disinfecting boot sector viruses. Boot sector repair is best accomplished by the use of antivirus software. Because some boot sector viruses encrypt the MBR, improper removal can result in a drive that is inaccessible. However, if you are certain the virus has only affected the boot sector and is not an encrypting virus, the DOS SYS command can be used to restore the first sector. Additionally, the DOS LABEL command can be used to restore a damaged volume label and FDISK /MBR will replace the MBR. None of these methods is recommended, however. Antivirus software remains the best tool for cleanly and accurately removing boot sector viruses with minimal threat to data and files. Creating a system disk.When disinfecting a boot sector virus, the system should always be booted from a known clean system disk. On a DOS-based PC, a bootable system disk can be created on a clean system running the exact same version of DOS as the infected PC. From a DOS prompt, type: SYS C:\ A:\ and press enter. This will copy the system files from the local hard drive (C:\) to the floppy drive (A:\). If the disk has not been formatted, the use of FORMAT /S will format the disk and transfer the necessary system files. On Windows 3.1x systems, the disk should be created as described above for DOS-based PC’s. On Windows 95/98/NT systems, click Start | Settings | Control Panel | Add/Remove Programs and choose the Startup Disk tab. Then click on “Create Disk”. Windows 2000 users should insert the Windows 2000 CD-ROM into the CD-ROM drive, click Start | Run and type the name of the drive followed by bootdisk\makeboot a: and then click OK. For example: d:\bootdisk\makeboot a: Follow the screen prompts to finish creating the bootable system disk. In all cases, after the creation of the bootable system disk, the disk should be write protected to avoid infection.

Tried everything to boot your Windows based system, but it is still unbootable? Unable to find out the exact cause for unbootability of your system? The most obvious cause for the above scenarios is severe damage in file system. In most cases of file system corruption, a Windows user encounters a boot error message that does not allow him/her to access the data saved in the hard drive. Few major causes of corruption in file system are improper system shutdown, virus attack, application malfunction, and operating system damage. These scenarios can be easily surmounted if the user has created an adequate backup of all his hard drive data. However, in the absence of an updated backup, the user needs to opt for powerful Data Recovery solutions.

Consider, while trying to boot your Windows Vista based system, you receive an error message :

“windows failed to startup properly, a resent hardware or software change might be the cause.”

The moment the above error message pops up, the booting process stops, rendering to inaccessibility of hard drive data.

Cause:

Damage in Windows file system.

Resolution:

To resolve the above error message, you will need to boot your system using ‘Startup Repair’ option. However, there is a possibility that this option may fail to boot and display the below error message:

“startup repair cannot repair this computer automatically.”

In such cases, if you wish to boot your system, then you can:

Perform a system restore to a particular restore point.

Use Windows Memory Diagnostic Tool to boot your system.

Run CHKDSK command.

Format and re-install Windows Vista operating system.

Re-installation will surmount the above error message and allow you to boot the system. Though the system becomes bootable, all the previously saved hard drive data becomes inaccessible. To access that data, you will need to opt for effective Data Recovery Software. Such data recovery tools scan a formatted Windows based hard drive and recoup all lost files.

Windows Data Recovery Software recovers all lost files post formatting. The Data Recovery application performs recovery in three simple steps. Compatible with FAT12, FAT16, FAT32, VFAT, NTFS and NTFS5 file systems, the recovery tool supports recovery of 185 different file types. It is designed for Windows 7, Vista, XP, 2003, and 2000.

There are many ways by which logical corruption in Windows Vista can occur. In most cases, the operating system becomes un bootable, leading to inaccessibility of data saved in your hard drive. Understanding the criticality of your data, Microsoft has embedded a powerful feature in Windows operating system, ‘Startup Repair’, to overcome all kinds of Windows booting and data inaccessibility problems. This feature can be accessed from ‘System Recovery Options’ or can also be installed on your hard drive. While the feature is useful in repairing most of the file system corruption problems, there is a possibility that it fails to repair your operating system and the data saved in your hard drive remains inaccessible. In such cases, if you want to access your hard drive data, then you need to restore the files using an updated data backup. But, with inaccessibility of an updated backup, you need to use an advanced disk recovery application.

Consider a practical case, where you encounter the below error message while trying to boot your Windows Vista based system:

“no bootable devices, please insert boot cd and press any key”

To overcome the message, when you run Startup Repair, you encounter another error message stating that your system can not be repaired using this feature:

“Problem Event: Startup RepairV2Problem Signature 01: External MediaProblem Signature 02: 6.0.6000.16386.0.0.0.0Problem Signature 03: 0Problem Signature 04: 65537Problem Signature 05: UnknownProblem Signature 06: Bad DiskProblem Signature 07: 0Problem Signature 08: 0Problem Signature 09: UnknownProblem Signature 10: 1168OS Version: 6.0.6000.2.0.0.256.1Locale ID: 1033″

After the above error message pops up, your hard drive data becomes inaccessible.

Resolution:

In case the Startup Repair option fails to repair, the next best option is to reinstall Windows Vista operating system. Though this option allows you to boot your system, it also deletes the data saved on your Windows Vista based hard drive. To access the deleted data post formatting, you need to search for a third-party disk recovery utility. Such hard disk recovery use powerful techniques to recover formatted data and to restore it at required location.

Stellar Phoenix Windows Data Recovery supports complete formatted data recovery from FAT12, FAT16, FAT32, VFAT , NTFS and NTFS5 file system based partitions. The disk recovery software can be installed on Windows 7, Vista, XP, 2003, and 2000. It supports recovery from all kinds of storage media, including memory cards, digital cameras, etc.
