Boot issue, possible Grub error - Linux Setup, Configuration & Administration

I've installed Red Hat 9 on my system, mostly successfully. The current major bug is that the system will not boot from the hard drive, though it does boot from the Red Hat boot disk that I made during installation. The system goes through POST, then displays a text-mode blank black screen with a blinking cursor. The only change I have made to the Grub bootloader configuration is to comment out the splashimage line, thinking I had some funky video card issues. No dice.

    Default Boot issue, possible Grub error

    I've installed Red Hat 9 on my system, mostly successfully. The
    current major bug is that the system will not boot from the hard
    drive, though it does boot from the Red Hat boot disk that I made
    during installation.

    The system goes through POST, then displays a text-mode blank black
    screen with a blinking cursor. The only change I have made to the Grub
    bootloader configuration is to comment out the splashimage line,
    thinking I had some funky video card issues. No dice.

    I have two hard drives. hda is loaded with Win98. hdb is devoted to
    Red Hat. Partition information (from fdisk) and the grub.conf file
    listed below.

    Any help gratefully accepted...

    to rerun grub after making changes to this

    Have you tried reinstalling grub? grub-install re-writes the MBR to the
    drive. OTOH, I'm not sure you can use semicolons to comment stuff in
    grub.conf..?

    According to the information you supplied from both your fdisk and
    grub.conf, you Red Hat Linux hard drive is hdc and not hdb. Your grub.conf
    file supplies the clue you need.

    Try the using following modified lines in your /boot/grub/grub.conf file;

    Use the pound sign to comment out the line not the semi-colon.

    # splashimage=(hd1,0)/grub/splash.xpm.gz

    Use the hard drive partition and not the partition label.

    kernel /vmlinuz-2.4.20-8 ro root=/dev/hdc5 hdd=ide-scsi
