Windows 7 repair

[TechKnowCase]

Hello,

First, it all started when I wanted to try tails to show some stuff to my friends at school. So I downloaded tails (2.0 and this version came out the day I tried to install it), installed it on a dvd-r (non rewritable disk) and didn't work. Every time I try to boot the screen freze and become more and more white. I realised that my laptop was hot as f*ck. Enven tho, it didn't work so I brought a dvd-rw and worked.

Next, my problem is that when I chose the windows boot manager, it does nothing. When I press the power button to shut it, it stop in <1sec. (other wise it supose to take more). So I try to take my paid copy of windows 7 (brought it on bittorrent ) and when I try to do fix computer, it says that I need the CD from another version of windows.

So yeah, can some one helps me to repain/ reinstall windows without loosing any data.

If you have access to another computer and a USB drive then you can reinstall using microsoft's tool http://www.microsoftstore.com/store/msusa/html/pbPage.Help_Win7_usbdvd_dwnTool

and booting from USB. I would recommend reformatting your hard drive but if you have important files then you can try without reformatting.
