Unable to boot on WinXP after Fedora Core 2 test3 install

[Marco Bambini]

I have a laptop (Acer Aspire 1300 with a 20GB HD) with Windows XP in 
the first partition (15GB) and Fedora Core 2 test1 in the second one 
(with GRUB for the dual boot and it always works fine). I have decided 
to install Fedora Core 2 test3 (with the erase linux partition option) 
and the installation works fine.

But when I try to boot on my WindowsXP partition (with Grub) nothing 
happens...
I am now UNABLE to boot into my WindowsXP partiotion...
I have read that others have the same problem after the Fedora install 
... but I haven't found any solution that works for me.

Anyone can help me?
