You need to chroot the environment before running grub cmds. as root do the following while running from a live linuxcoin session.
mkdir myhdd
mount /dev/sda1 myhdd
mount -o bind /proc myhdd/proc
mount -o bind /sys myhdd/sys
mount -o bind /dev myhdd/dev
chroot myhdd
Now you can purge and reinstall grub. I would do the above then follow the ubuntu fix up guide. I don't know where this bug comes from I've tested the installer numerous times and always had success ?
Yea, thanks for the reply, I give up, there are the cmds u give me then there are a crap load of cmds from the other, it will just lead me to no where as i been trying since my first post in this thread. nothing but waste of time and power running a second pc trying. I'll just stick with my debian 6.0.2.1 install. Trying to mix ubuntu cmds with & fixes with linuxcoin cmds and mixes of grub version, my head is spinning.
I will send you a donation soon after I get my second gfx for giving your time trying to help me.
