Grub error 13 with redhat 6.2
I am still using redhat 6.2 for some things on an old machine and I've just installed fedora 4 on there. It did use LILO but I let fedora install grub and now when I try to boot redhat with grub it gives:
Error 13: Invalid or unsupported executable format.
Redhat is on hda1 with its boot partition on hda2.
Fedora is on hda4 and doesn't have a seperate boot partition.
To try to boot redhat I do
kernel /vmlinux-2.2.14-5.0 ro root=/dev/hda1
I've spent ages searching for an answer and even tried running grub-install on hda2 so any help would be very appreciated.
