i have linux mint 10 installed on my system and i want to install fedora 14 too .

since fedora 14 comes with grub legacy and not grub 2
so,if i install fedora 14 would the grub 2 that comes with Linux mint be over-written by grub leagacy

if yes,then how do i install fedora 14 withoust losing grub 2

You have the option to not install and overwrite the current boot loader after installing of Fedora 14. Just make sure to set up proper partitions so you don't lose your Linux Mint installation.

Good luck.

When installing fedora, you'll have an option on where to install grub. Just install grub in the boot partition of the fedora installation, or the root partition if you don't have a separate /boot partition. That way, the existing grub menu in the MBR wont be overwritten.

You'll probably have to edit mint's grub menu to allow you to boot into fedora. Also, fedora may automatically add mint as a boot option (you can edit this during installation), so you might want to edit the fedora grub menu as well so you don't have to go through 2 grub menus when booting fedora.
