I have Microsoft Windows Xp installed on my Primary Drive C: and I had a Mint boot disc that I would pop in and load from. Well I got tired of this disc and installed a new hard drive in my computer so I could use Mint as a secondary OS. Everything went good in the install, and I put Mint on the second drive. But when I boot my computer the GRUB menu only shows Linux Helena Mint 8 to load from and no Xp.

Xp is still currently installed on the computer in the Primary drive, but how do I inlcude it in the GRUB boot menu or boot it at all???

Im sorry for any inconvenience but I would really greatly appreciate any help...

1st thing I would try
Open a terminal window and run

That worked perfectly! Thank you so much!
