This one is weird. Our Micron notebook computer with NT 4.0 (+SP4) and RH 6.0 somehow has the root directory on /dev/hda6 and there is NO /dev/hda5. I have no idea how the person here set this up. The partitions are: hda1 : FAT16 hda2 : extended (?) hda3 : linux swap hda4 : linux swap (no hda5 listed) hda6 : ext2fs (/ directory) hda7, hda8, hda9 are also ext2fs partitions (usr, tmp, etc) hda10 linux swap. The RH 6.2 installation program dies when it cant find the hda5 partition. I understand that the hard drive partition table may be corrupted, but this machine has been working great since it was installed with NT/RH 6.0.
I have no idea how one would get a computer in this state, but that is definitly a state that the machine should not be in. With this being the case, I can only say that the installer was never meant to deal with invalid partitions, so it is not surprising that the installer is failing. I would recommend reinstalling the machine and recreating the partition table during the process. What does "fdisk -l /dev/hda" show? I cannot come up with a way to get a hard drive in this state.
