Question reinstall the w7 OS on 860 evo

[ppdemo]

Hello guys, as the question says, how do I do it? should I format from the start or do something else? because I've seen that there is talk of secure erase and also to reset it to factory values. I the first time, from the start, install it as if it were a hdd disk. Now I need to re-delete the windows to make a clean installation back. i hope your answers thanks.

This is how it needs to be done, but it requires that you have installation media. If you don't have installation media, you need to GET installation media from a reputable source or the manufacturer if they still offer it.
