Hi :)
I suspect you have done the same as me, the same as the last thread in this list (which i didn't quite understand but suspect i just need to re-read sometime). The SSD is formatted using a GPT table rather than something unsuitable for SSDs?
What i tried was booting into my old OS and then got to a command-line and
tried
sudo update-grub
Now i can completely successfully boot into any of the OSes on my old drive. There is even a listing for the new drive but when i try to use that one the machine fails to boot up.
So, i unplugged the old drive and left the new one in. A LiveCd session allowed me to reinstall (or install) Grub 2. So now if i have the old Sata Drive plugged in i get all my old OSes but if i unplug it i get the new one. Annoyingly the new one forces me into Mega Glest rather than regular Glest so i'm quite happy staying with the old one.
I do have a feelign that if i just set-up a small partition
at the front of the SSD to dedicate to being a boot-partition and install Grub2 to that then i could have both but i think i would probably still be booting into the old OS!

Tom :)
