How can I remove everything that is in the harddrive?

[Abbe]

Hello there. Well, I installed Windows 7 3days ago and I did not feel comfortable about it. It kept bugging out with almost everything and the performance on my games just became weaker than when I had Vista installed. Well, I tried to uninstall Windows 7 and get back to Windows Vista while using this guide here: How to restore a Windows 7-based computer to a previous Windows installation by using the Windows.old folder I used that command program in the "repair your computer" section in Windows 7 boot menu but I accidentally typed in wrong commands in there so I closed the command program and restarted my computer. When I did that I actually thought that everything would be fine when I suddenly saw that I had Windows Vista and Windows 7 installed:sarc:? I runned Windows Vista and hoped that I would work but only a blank screen came up after I clicked on it. Windows 7 did not worked eather because I had already moved my system files when I tried to switch back to Vista. Now I have reinstalled Windows 7 and the old programs that I had are on Windows folders, I now have folders that I should not have a such. Its really really messy right now and I just want to clean my harddrive and download Windows 7 from scratch. I really need help with deleting everything in my harddrive and I want to know if the "Acer" screen after I start the computer will pop-up if I clean my harddrive because thats the only place I can boot Windows 7 from if I deleted everything in my harddrive.

Do you have either Vista or 7 on cd/dvd?

If you have the discs, you can format the entire drive during the OS setup and installation.

Yes I do have Windows 7 on my disc, but how can I format the entire harddrive then?
