How to wipe clean my Vista Hard drive

I need step by step instructions on how to completely erase my hard drive (Windows Vista) and after that install Windows 7 operating system. I've failed at this type of upgrade in the past.

What Are You Trying To Accomplish
by Grif Thomas Forum moderator / December 19, 2011 9:04 AM PST

You mention that you're trying to "upgrade" something.. Please describe exactly what you are trying to do.

To clean off a hard drive and install a new operating system, you simply need to place the new, legal operating system in the DVD/CD drive, let the system boot from the CD, then use the disc's instructions to delete all current partitions, then format the drive and install the operating system.

On the other hand, if you simply want to wipe a hard drive so secure and nothing remains, then using a boot disc such as the one at the DBAN link below should get it done for you.

Hope this helps.

New Operating System
by Glock45Cal / December 19, 2011 9:18 AM PST

Hi Grif,
Thanks for the reply. In the past when attempting to upgrade my operating system I've run into difficulty. It seems that when i've installed a new operating system it didn't completely erase the original OS. It gave me two operating systems and took up a ton of my hard drive space. I must be doing something wrong. I currently have Windows Vista Ultimate and I purchased Windows 7 for my upgrade. I hope this was a good move on my part.

Well Then, An UPGRADE Is Slightly Different

In reply to: New Operating System

The Upgrade option moves your files, settings, and programs from Windows Vista to Windows 7 as long as you have the appropriate versions of both operating systems. Microsoft has put out a whole list of webpages which should let you upgrade successfully.. Here's a link to one such page:

You didn't tell us which version of Windows 7 you've purchased.. That's important, you'll need Win7 Ultimate if you want to perform the standard 'upgrade' process from Vista Ultimate which saves all files and settings.. You won't be able to "upgrade" to a lower version of Win 7 from what you already have with Vista, in other words, going "down" from Vista Ultimate to Win 7 Pro or Win 7 Home Premium, you can't do the normal upgrade which maintains your current settings and data. You need to do a clean install which is basically what you want anyway.

Hope this helps.
