I baught an HP P6-2100 for my son and windows in this house has always been a swear word. He grew up on Ubuntu and we are having a heck of a time installing it on his computer. It came with windows 7 home premium on it but when we try to boot the install cd it hangs wile the installer GUI is starting and freezes (numlock froze, no typing, no mouse) at the brown screen. Any help would be appreciated, thanks in advance.
