Install Fedora.  During install it asks where grub should be installed.
Or you can skip grub install.  Then find a grub.iso and make a grub boot CD.
(http://www.bybent.com/grub.iso has one I built; "info grub" select
Installation, select "Making a GRUB bootable CD-ROM" to do it yourself
(you've no reason to trust my .iso)

Boot from the grub.iso, figure out which drive it thinks is the USB drive (probably hd1).

run

root (hd1,0)    # assumes your /boot or /(if you have no /boot) is the first partition
setup (hd1)

Done.
