sir, i am trying to install fedoracore4 on my system but it stopped in the grub

there are any way to install fedora from grub ......if any what are the instructions for that

do you mean that it failed / stopped when it was at the stage where grub was being installed? if so, then you can boot from the 1st fedora cd (or boot from the dvd if you have that), and at the initial prompt where you would originally hit "Enter" to install it, type: linux rescue, and hit enter. that will bring you into the rescue mode. you'll go through a keyboard / language setup, it'll ask if you want to start the network interfaces (unnecessary), and it'll bring you to a prompt after telling you you can mount the filesystem with: chroot /mnt/sysimage. so at the prompt, enter the command: chroot /mnt/sysimage. next, enter grub-install /dev/hda
that should install grub to your hard drive and now all you have to do is reboot so type: exit, and remove the disk from the rom drive.
