dual boot problems

[hanfamily at earthlink.net]

Hi,
I bought a new compaq computer with win xp partitioned the
drive installed fedora with grub to load. I had everything
working then I booted windows it goes into pc recovery and
overwrites the boot section so it only will boot windows.
Is there a way to get this to work?  If not is there a 
way to make a boot cd to access the linux partition.
              Thanks
              Linda
