There is no reason that a prior operating system install should interfere with installing GRUB. Removing DSL is unlikely to make any difference except by luck.
In any case:
Dec 27 23:32:56 ubuntu grub-installer: malloc: ../bash/dispose_cmd.c:197: assertion botched^M
Dec 27 23:32:56 ubuntu grub-installer: free: start and end chunk sizes differ
Dec 27 23:32:56 ubuntu grub-installer: Aborting...
Dec 27 23:33:10 ubuntu grub-installer: error: Running 'update-grub -y' failed.
That looks like a fairly random crash in bash to me. Wolfgang, perhaps this is bad memory?
