Just an observation:
How much usage do you expect to get from the research effort to
be able to do smart multiple OS booting ?

I've got some 6 IDE's which I interchange between mother-boards.
Some with 30 ...40 partitions [for n-o].
Only one little IDE boots - to DOS
All others need fd0s to boot: n-o, linux, DOS.
I can post you megabytes of text on analysing MBRs ...etc.
BTW n-o's Partitions.Tool with the source code is very good.
But life is too short, unless you can amortise the cost over
 many systems.
We can NEVER get it "right".
Don't invest time researching that which may be irrelevant soon.
Don't get married to the hardware, which will soon be redundant.
Consider using fd0 booting.
How much time/effort do you want to spend 'tuning' an apple which
you'll eat in 20 seconds ?
