My problem is that a virus maybe has infected the boot section. I can boot with the Windows disc, but I can not proceed with the installation of Windows 7. I have tried that, but then I got an error message which said that it could be a hardware error.

It could ofcourse be a hardware error, but I think that I've had a virus, because Norton and the firewall was shut of and security updates were blocked. A colleague adviced me to boot the PC with Knoppix and then install Windows. But you say that this is not a good idea. Do you mean that it is impossible to do or just that it's a stupid thing to do?

Be sure to do a full format of the hard disk to get rid of anything nasty that you may have installed on it.
