Paul,
I may have missed it, but why are you using such a old version of
Ubuntu?  Why not 9.04 Jaunty Jackalope?

Jim Brewer

Because I am trying to run EMC2. The EMC2 people tell you not
to install 9.04 for some reason. http://linuxcnc.org/

I had it running today and then I reinstalled it from the live
version and it broke the old install. Grub Error 18 again.  I have
never had so much trouble installing Linux and I have been doing
it for 11 years.

They really keep you in the dark for about an hour as it
is installing itself on the hard disk from the "live" version
running off the DVD.

I don't know whether it formats the hard disk and loads a
virgin copy or merely reads what on there and does not copy
the new software over.

I don't want to spend $500 on a new mother board processor and memory
if I don't need to. I need to find out why I am getting Grub error 18
and how to fix it.
