How do I remove Windows for Linux?

This topic has been moved from the section Opinions and Experiences to section Linux/Free BSD by Grumpy9117

CCleaner is something that cleans up junk files, so it'd be of no use here. DBAN is an option. Use DBAN to format the drive, and then install Linux from a Live CD (I think most, if not all distros have them).

If I might ask... Why are you so interested in dumping Windows completely anyway? Dual booting would be a good option, as it also means that you're easily compatible with Windows programs too. I know Linux has WINE, but...

If you are truly interested in dumping Windows and installing some version of Linux, almost all installation media comes with a mechanism for wiping clean a disk for use for Linux, it's mostly a matter of picking a distro and finding out how they do it in their installer.

As far as Dual-booting, it's not a bad idea to keep Windows around if you already paid the MS tax when purchasing the machine (esp. if you play games or use some other SW that doesn't have a Linux analog, which is getting rarer and rarer), plus you get the nerd cred of having a duual-boot setup (although you may eventually move away from Windows altogether  )
