I installed kubuntu herd 4 on my old gateway p3 1ghz. I had a clean 400gb drive for the install (the only drive in the machine). I chose the guided partioning and accepted the defaults. The entire install went smoothly, but when I rebooted i got the grub error 18. The only way I found to fix it was to reinstall and manually add a /boot partition. I'm not sure I did it right or if I chose a good size for the /boot partition (I used 100gb), but after reformatting and reinstalling, everything worked fine. I'd guess that most new linux users would have just given up and gone back to some other os when the grub error occured. If there is any way to detect that a /boot partition is required, it would be nice if the partitioning step did that automatically. Everything else looks good! Nice job!!
Is this symptom still reproducible in 8.10 alpha?
