Triple boot problems

[Setarkos]

Hi there

I had Win7 installed on my Laptop and wanted to set up a triple boot with Fedora 12 and Mint 8.
So I installed Fedora 12 and it worked loading grub and offering Win7 and Fedora as choices.
Then I installed Mint hoping for the Grub2 to recognise Fedora and set up the triple boot but it didn't and I can now only boot into Win7 or Mint.
sudo update-grub doesn't help
How can I configure grub2 to offer me all three OSs?

Thanks in advance

I do not know fedora but copied this thread. It seems that the initrd file is not in an expected location and the osprober cannot find it. I saw were some did manual entries like this in 40_custom or modified the prober to look in the correct place:
