Seems like a common problem but after much reading on forums I'm unable to solve it. Installed RedHat 9.0 exclusively on a machine. Here are the partitions

/dev/hda1 /boot
/dev/hda2 /tmp
/dev/hda3 swap
/dev/hda4 /

When I boot, after the splash screen, I get the error
Invalid or unsupported executable format.

root(hd0,0)
Filesystem is ext2fs, partition type 0x83
kernel /vmlinuz-2.4.20-8 ro root=/dev/hda4

I can only boot with my floppy now.
Any help will be appreciated

This is probably a problem with grub. Look at /etc/grub.conf and see if there are any problems. In particular check to make sure that you have the right file system type for /. After you are sure that /etc/grub.conf is correct you may need to run grub-install.

here is a grub HOWTO:

Thanks for the link.
GRUB docs and functioning seems relatively straightforward. However I cant seem to nail down my problem with that.

Is it normal for GRUB to report the filesystem as ext2fs even though its ext3fs?

"Is it normal for GRUB to report the filesystem as ext2fs even though its ext3fs?"

No. If you can figure out why grub is doing that then you probably will have the problem solved. Also check /etc/fstab to make sure that / is correctly configured in /etc/fstab.

I don't know how your boot floppy is configured but it is possible that there is a grub.conf on it. Check to see if there is a grub.conf on the floppy and how it describes your / partition.
