Sounds like what I would "try", after making an "full spindle"
AcronisTrueImage10
image that includes a copy of track 0 along with MBR (if I had the space
somewhere).
Note that deselecting the Windows partition in Acronis also skips track 0 and
the MBR.

It would be a pain to reinstall Ubuntu because I have made lots of
modifications to the default install, not just installing software but
actual config changes.
I think my best bet would be to format the Windows partition, shrink
it down to like 10 MB, and leave it in place. That way I get the
space back but don't have to worry about messing up the boot order or
mappings.
