I've just filed bug 0004634. Grub won't install onto my pata drive now that I have a sata drive installed. This is grub 0.97 on CentOS5.5. Has anyone else encountered this? I'm guessing that I can always install Fedora on hda, which should give me a working grub, but I was hoping for something a little less involved.

Thanks, Dave Mackay

Is the PATA drive on your Primary Master connection?

If you use Gparted live CD or Parted Magic, how do those drives show up?
