Please be more specific. Are you trying to boot with an emergency anti-virus disk? If you're using the Windows CD, then what is the "virus windows setup" that you're talking about?
If you boot with the XP disc, you should be able to access the Recovery Console and choose 'Repair' (press 'R').
Select the installation of Windows that needs repair, enter the admin password (if prompted) and then type 'fixmbr' at the prompt. You'll get some warning messages, but clearing the master boot record should not impact your data. That is, unless there's a problem with the drive itself, in which case, you're probably hosed anyway.
But I'm assuming that since you were willing to reformat the entire drive, data isn't an issue. Clearing the MBR is much less drastic than a full reformat and, if successful, would mean that you won't have to reinstall Windows.
If it works, this should allow you back into Windows so that you can take steps to remove any other viruses that may be present.
