My machine looks like this - a bit of a mess I know.

/dev/hde1 Windows 95
/dev/hde2 Linux swap (set up for Redhat 9)
/dev/hde3 /home (for Redhat 9)

/dev/hda1 Mandrake 9.2 (includes /home /boot )

/dev/hdc1 /boot (for Redhat 9)
/dev/hdc2 / (for Redhat 9)

I have grub installed controlled by menu.lst from Mandrake see below. With it I can boot into Mandrake and Windows. When I try Redhat Grub almost immediately displays the line -

kernel (hd2,0)/boot/vmlinuz-2.4.20-28.9 root=/dev/hdc2 devfs=mount acpi=ht resume=/dev/hda5 splash=silent vga=788

then Error 15: File not found.

I can't see what file it's not found. I can boot into Redhat with a floppy boot disk. Can anyone help? Thanks

The contents of menu.lst

well...as a first step, check out that every file that's listed in RedHat's section actually is where Grub tries to search if some of them is missing, that's the problem....vmlinuz, initrd and the splash image (silent) should be found in order to boot normally so load up Mandrake or something and do a search.

Thanks for the quick response. The problem was with the line

kernel (hd2,0)/boot/vmlinuz-2.4.20-28.9 root=/dev/hdc2 devfs=mount acpi=ht resume=/dev/hda5 splash=silent vga=788
was that it should have been

kernel (hd2,0)/vmlinuz-2.4.20-28.9 root=/dev/hdc2 devfs=mount acpi=ht resume=/dev/hda5 splash=silent vga=788

as boot is in it's own partition (hd2,0) it shouldn't include /boot in its path.

Similarly with next line.

Thanks for your help
