Important Tips for Restoring an Unbootable Hard Drive

Have you ever tried to restart a machine only to find it won’t boot? For whatever reason, you get a warning message informing you that disaster might well have struck… and you’re staring in the face of what could be a very bad day. Well, don’t panic yet. There are a few tricks you can try that may get that machine booted
. All is not lost until you know, with 100 percent certainty, that the drive will not boot — and even then, you can possibly recover your data. Here are some tips that can help you to get that drive booted and your machine recovered.

1: Boot from a restore disk

With many operating systems, restore disks can be created and used to deal with such disasters. The problem with this usually arises because the user hasn’t made a restore disk. I always tell users that one of the first things they should do when they get a new computer or install a fresh operating system is create a restore disk and then put it somewhere safe. That disk can really save your hide — especially in cases such as an unbootable drive. Now, every operating system approaches the restore disk differently. For example, some Linux distributions, such as Ubuntu 11.04, let you use the Live disk as a restore disk. So even if you didn’t create a restore disk, you can just download the same release that’s installed on the machine and use that as your restore.

2: Use the install disk

If you didn’t create a recovery disk in Windows, but you have the full installation disk, you’ll be okay. Those disks include recovery tools that can be accessed by pressing R at the Welcome To Setup screen. The tools let you fix boot problems, restore the hard drive from image, diagnose memory, and perform system restore. Note: The system restore typically can work only if the system restore partition is intact.

3: Get to know BartPE

There are tools… and then there is BartPE. BartPE is a huge challenge to build. But once you have it, you have a serious tool for fixing serious problems. Bart E creates a complete, preinstalled Win32 environment on your hard drive that allows you to use many of the tools available for repair. You to run check disk on your drive, which could easily solve your problem.

4: Rebuild the MBR

In many instances, the problem is a corrupt master boot record (MBR). If that’s the case, the MBR needs to be rebuilt. This process will vary, depending upon the operating system you use. With Windows 7, the necessary tool is Bootrec.exe, which can be found in the Windows Recovery Environment. If the operating system uses Grub 2 and the boot loader was lost after a Windows installation (with the intent to dual-boot), there is a tool called Grub4dos, which can certainly be a lifesaver. If no Windows environment is on the machine, grab that Live CD and you’ll have all the tools you need to rebuild your Grub boot loader. The specific tool you want is grub-install, and to rebuild the grub menu, update-grub.

5: Remove the drive

If all else fails, pull out the drive from the machine, attach it to a machine known to run, and see if the drive can be seen at all. It is possible that the reason the drive will not boot is due to physical damage. If the drive can be seen but not accessed, most likely the partition table has gone corrupt. But if the drive can’t even be seen, especially using a Linux machine to view it, the drive might well be physically damaged. If the drive can be seen and accessed, the problem is probably the MBR. I would highly recommend that at this point, you copy your data over to another drive — just in case.

What has saved you?

There are plenty of ways to recover that unbootable drive, but the techniques above have always brought me the most luck. What about you? If you’ve found a more reliable or efficient way to recover a drive that refuses to boot, share it with your fellow .

Lock your PC with a USB flash drive

PREDATOR is freeware utility that locks your PC when you are away, even if your Windows session is still opened. It uses a regular USB flash drive as an access control device. When you leave your PC you just take your USB drive with you and Predator will lock your PC. While you are away Predator records all security-related events in a log file. By reading this log, you will know if intruders have tried to use your computer while you have been away. When you return back to your PC, you put the USB flash drive in place and your PC will be unlocked.

Its easier and faster than closing your Windows session, since you do not have to retype your password when you return.

How to install Predator in your PC

1. Download and extract Predator.zip
2. Start InstallPredator.exe. When prompted for an installation folder, accept the default path "C:Program FilesPredator2" or select another folder on your hard drive, but do not select a folder on your USB flash drive. Never install PREDATOR on removable media.
3. After installing run the application from Windows program menu or the desktop shortcut icon.
4. You will get a message box like this

• Type the password of your choice in the "New Password" field. You will use it to unlock your session if you lose your USB key.
• You must enter at least 6 characters, letters, figures or signs. The password is case sensitive (uppercase and lowercase letters are different).
• Check that the drive letter displayed under "USB key drive" actually matches your flash drive or choose the correct letter from the dropdown list.
• Click the "Create key" button
• Finally, click "Ok"

    7. Predator will exit after this setup procedure.
    8. Finally, click the Predator icon installed on the desktop to restart the program. When you restart
        Predator, initialization takes a few seconds, then a green ball icon should flash in the system tray.
        If the Predator icon is blinking then everything you have done is OK.
