need help urgent

[Phillip Whiteside]

Hi,

I agree with the previous reply. A great place to start on the forum is at
http://ubuntuforums.org/showthread.php?t=1014708 which covers the issue of
re-installing the Win7 loader to replace grub. It is also a good place to
seek information on and ask for help on.

Regards,

Phill.
