How can I install Windows after booting with Knoppix?

[Harry Kuhman]

I am using Knoppix to boot an infected PC. I then want to install Windows 7 on it. I boot with Knoppix, but how can I then install Windows 7? I have to insert the Windows CD, but I can not remove the Knoppix while I am running Knoppix. I try this, but then I get the message "unable to eject device
volume knoppix is not mounted". So how can I proceed with my installation of Windows 7?

You're talking nonsense. You don't need Knoppix to install Windows, and I don't know of any way that you would install any version of Windows using any version of Linux. Just shut down Knoppix. Remove the disc. Insert a bootable Windows install disc. Boot it. Install Windows, making sure that your computer boots from disc before hard disk. Be sure to do a full format of the hard disk to get rid of anything nasty that you may have installed on it.
