I want to sell my old Dell Dimension 3000. I want to completely erase the computer before I do this for security reasons. No Windows CD came with the computer when purchased back in 2005. I think it would be easier to sell the computer if Windows was installed but don't know how to get Windows back on the computer after erasing. So if I do erase the HD what would be my best option for getting Windows on it:
Do I have to buy Windows XP?
Is there a way to download Windows from Dell onto CDs for free since they CDs did not come with the system?
Or any other suggestions on getting rid of all data without erasing the HD?
Thank you.
