ok i installed the fedoracore 7 with grub bootloader but after complete setup and restart it loads to windows without any bootloader shows up.so i tried loading the dvd and try to install the grub bootloader again and i get the message that NO KERNEL PACKAGES found or installed.something like that and then it restarts.yet i guess the os is installed and the only problem is the bootloader.anyway i can fix it?
