Boot image problem

Hi,
I installed Avast! and asked me if I wanted to run a scan on start up. Now, Avast! saved my server from a virus, and caught it on start up, so I clicked “YES”. My computer restarted, and I think Avast! started scanning. However, I have a custom boot logo, and couldn’t see anything as it scanned. Xpize installed the logo, if that helps. Uninstalling Xpize kills all themes, including windows XP itself.

Any suggestions?

Please check your c:\boot.ini file - is there a /noguiboot switch inside?
