If you are currently preoccupied with questions such as “how to erase hard disk drive?”, then I think I will not have to make much of an effort to conclude that your computer system has failed completely and needs a reboot. I say so because apart from a complete system crash, there aren’t that many reasons that justify erasing a hard disk drive. Now, coming to the main point, I would like to tell you that erasing a hard disk drive is quite easy and all you need is some basic knowledge about installation procedures and a CD of Windows Operating System.

The answer to how to erase hard disk drive is basically a step-by-step Windows reinstallation process that starts with turning on your computer and inserting the Windows CD into your CD/DVD drive. After this, you need to switch off and restart your computer and keep pressing any of the keys on your keyboard. This signals your computer to boot itself from the CD. When you do this, you will see the Windows GUI (Graphic User Interface) on your screen, which will provide you with options and help you in selecting the one that you might need.

If you keep following the instructions, you will eventually come across the option of deleting partitions of your hard drive, making new partitions and reformatting each of the selected partitions. You can say that you have succeeded in erasing your hard disk drive when you have performed all the three procedures as described above, one after the other. After this, you can be sure that your hard disk drive is completely clean and ready for the installation of Windows Operating System.

Erasing the hard disk drive also removes viruses and other malicious software codes that might have contributed to the system crash in the first place. It is the most effective way of bringing your computer back to its original state, although you might have to sacrifice some of your data that might be stored on your hard disk drive.
