There are several complications or problems that can occur while running Ubuntu and Windows in either a dual-boot or Wubi.

Most distros (versions of linux, Ubuntu is a distro), such as the tiny sliTaz, can fix most Windows problems and there are specialist distros (such as Trinity Rescue Kit and SystemRescueCd) that can fix a lot more.

This guide assumes Ubuntu either as a LiveCd or installed on hard-drive but other distros could be used just as easily.
