Save, Restore, Fix a Broken MBR with MBRWizard [Windows]

MBR, if you are unfamiliar, is the first sector of your hard disk. It is just 512 bytes in size, but boy are those 512 bytes important or what? The MBR is used for bootstrapping operating systems, holding the primary partition table of your disk and other important information. You take this information away and chances are you will not be able to boot the operating system.
While installing the operating system, the installer takes care of writing appropriately to the first 512 bytes to allow the operating system to boot and detect partitions. Once that has been done, you do not have direct access to the MBR (which is generally not recommended). However, there are times when you need to take things in your own hand (like backing up MBR before restoring a hard disk image or an OS install, making a partition bootable, or recovering from a corrupt MBR etc), for such times there is a small utility you can use, called – MBRWizard.
MBRWizard allows you to save/restore MBR, fix a corrupt MBR, you can hide/unhide hard disk partitions, make a partition bootable or delete it all together, make a flash disk bootable etc.
fix mbr
MBRWizard is a command line utility you can download from here. Fire up Command Prompt and browse to where you have MBRWiz.exe stored (or else add the directory to your PATH variable), type MBRWiz and you will see a list of all the options. You can then decide which option to choose according to what you are trying to accomplish.
Here are a few examples.

To create a backup of MBR

MBRWiz /save=C:\savedMBR
You can then use this backup copy to restore MBR in case you ever have to.

To restore MBR from the saved file

MBRWiz /Restore=C:\savedMBR
repair mbr

To see an exhaustive list of all the partitions along with attributes

MBRWiz /List

To Hide a parition use

MBRWiz /Hide=Yes /Disk=0 /Part=2

To delete a partition

MBRWiz /Part=2 Del
You can find the complete documentation of all the options and how to use them, here. The site also lists how you can troubleshoot MBR problems when you cannot boot into the operating system. Although in such situations, you must have a way to boot from a CD, USB drive or (ahem..) floppy disk and be able to run MBRWizard. Check out how to make your own Windows Live CD, MBRWizard would be a nice utility to have on your live CD.
MBRWizard is a great tool to have everything is working fine, as well as when you need to fix MBR issues. You must have your favorite tools to jumpstart a problematic computer. We would love to hear about them so tell us in the comments.

5 Free Apps to Clone Your Hard Drive




Hard drive prices are so low now that it really makes sense to use an imaging program. That way you've got a perfectly cloned backup of your system exactly the way you have it configured in case of a crash, which is much more convenient than reinstalling Windows, activating, and loading all your applications all over again.

Here are four great apps to get the job done - without spending a dime!

DriveImage XML. Runtime Software has never placed too much importance on looks, and it's for a very good reason. Their software works really, really well. DriveImage was the first software I used to create images within Windows. Scheduled backups can be created with the Windows Task Scheduler and command line switches. DriveImage is free for private, home use only. Yes, Macrium Reflect does the same thing and looks nicer, but it's $39.99.

For a straight-up, drive-to-drive clone, you can use Runtime's Shadow Copy. Shadow copy is free for everyone, not just home users.

Like DriveImage, XXClone runs in Windows. It has an extremely simple interface, and gives you the option to copy volume ID to your destination and make it bootable. The interface also provides quick access to the Windows disk manager, in case you need to perform some quick drive tasks prior to cloning. XXClone is free for personal, private use.

Those who, like me, prefer imaging from the command prompt should try EaseUs Disk Copy. It's interface looks a bit like a Ghost/Partition Magic mashup. It's very easy to use, handles all types of internal and external drives, and will even work with dynamic disks. DiskCopy is free for everyone.

Linux buffs will urge you to try PING, which I mention in 5 Apps for a Painless Reformat. Ping can clone drives, create bootable recovery media, back up BIOS data, reset passwords, and clean your cat's litter box. Ok, not really, but it's got more tricks up its sleeve than any other free cloning solution.
