Hi,

I have vista already and i mede some partitions as fat 32 for fedora. I don't know how and when to install grub if i want to make dual partitions. Please tell me.

Hi,
to install fedora you need a linux filesystem, like ext3, you cannot install fedora on a fat32 partition.

To install grub you dont need to do anything, just insert the disc and install fedora it will install the grub for you automagicly.

Then can i make those fat32 partitions as unallocated space so that i can do the partitions while installing linux?
My other question is what should i do regarding boot loader(check it or uncheck it) in order to get dual partition?

For dual booting, you typically have to edit the GRUB configuration file to add the desired installations.

The typical installer gives you the choice of where to install GRUB, but it will not normally set up the config file.

One standard method:
Install OS #1---let the installer put GRUB on the mbr.
Install OS #2---tell the installer to NOT install GRUB
Reboot into OS #1, and add an entry in /boot/grub/menu.lst

Whenever I install a new distro, I go into /boot (on the new distro) and make soft links for vmlinuz* and initrd* (e.g.: ln -s vmlinuz* vmlinuz). This way, I can always have menu.lst entries that use the same names.

The "booting" link---below in my sig---might help.
