grub starter.
now i want to reinstall grub starter , let the directory /boot/grub/ have something ,or related grub starter files.

(hd1) /dev/hda2
(hd2) /dev/hda3

Let's start with the basics first. Is the your bios set to boot from the floppy drive as the first boot device?

In the /boot/grub directory, do you have a grub.conf file?

If so, can you post the contents?

I assume that you saw the RedHat guide here?

If not, and I am going by remote memory, try typing on as root user;

redhat-config-boot

See if this package is installed. If it is not, try installing it off the cd.

If it is installed, you should be able to install grub to a floppy.

I have just been looking around. See if your grub.conf file is in the /etc/ directory.

If it is at /etc/grub.conf, then post the contents, if you can.
