Thanks Jimmy. I haven't gotten that far, as I've done 6 or 7 installs
today and it will not install grub on anything but /dev/sda.
So now I've swapped the drives so that the new one is sda and this one
I'm booted from is now sdb, and am about to reformat it to suit me with
wheezy's gparted, then try another install. Broken damned installers.
After the last try, I rebooted to the dvd in live mode, thinking I could
do a grub-install from there, only to find that that boot had no trace
of the grub tools.
What a revoltin development that was!
Damned dvd has 3+ gigs of empty space and they can't find room for grub2
tools? Good Grief, they're staying up nights trying to make a stretch
install come up broken on the reboot.
I'll be useing my bigger lathe to make a big piss-elm club, same one I'll
use on the next person that thinks north of 70 yo is the golden years.
I'll call it my educational club. ;-)
So its off to do the 8th install to the same hard drive today...
