I Want to reinstall my lenovo laptop with windows 8.1?

I know I can reset my laptop to factory settings but doing that would just keep all those preinstalled softwares that came with the laptop when I first bought it. I should mention that I don't have the cd to do a reinstallation through my dvd drive. Note, in case I not being clear, I'm not moving to another version of windows. I just want to do a clean reinstall without any of those preinstalled softwares from lenovo. So what are my options, and if you could, please include all the necessary steps or maybe a link to a tutorial? Please don't comment by saying that it's much easier to uninstall those preinstalled softwares instead of doing a clean reinstall. I would very much rather perform a clean reinstall.

The levono factory reinstall is an image, that returns it to out of the box condition. This includes all the factory installed bloat ware. There's no way round this
The only way to get a clean install is to purchase a genetic windows 8 CD, even then you would probably spend just as long installing all the drivers.
It would be far easier to do a factory image reinstall and uninstall all the bloatware

The only odd thing is that you need to know what version of Windows 8.1 your computer has. For most people, it's just Windows 8.1 x64 bit. If you download the incorrect one, your laptop's product key won't work with it.
