Linux boot issues

OK... I've got Vista 64 on sda with EasyBCD installed. I installed RHEL on sdb, trying not to overwrite my Vista boot stuff. When I try to setup the NST Linux loader, I see that I don't have a bootloader (grub) installed on sdb (didn't see an option to do that during the install). Of course it doesn't boot into Linux when selected. It appears that I need to configure the NST loader, but I don't know how. Where should I go next? Thanks Ron
The GRUB install was the problem... For RHEL the correct selection is under advanced boot options. After a reinstall selecting the correct GRUB install point (boot sector, second drive) everything worked exactly as it should... Ron
