so I'm trying to install windows 7 again. I got a virus for some reason, I couldn't start up my PC anymore. So I formatted everything in the windows 7 installation(you know before the installation begins). There is nothing left of my old files. So after windows expanded the files it's starting to install the features, but then I get some error saying: could not set the offline locale information Error code 0x80FF000. After that I get a lot of errors saying that files are corrupt and that I have to run checkdisk utility. I don't know how to run that without windows explorer. So it would also be helpful if someone tells me how to run that without having windows on your PC.
The windows 7 dvd is fine, because I used it before on the very same computer and it worked. Only this time I'm getting these strange errors.
So if someone could tell me what to do with this error and how to run the checkdisk utility, I would be grateful.
