LL2 not booting if one extended partition is formatted to FAT 32

[gold_finger]

The difference between your setup and mine should not make any difference at all with regard to the system's ability to boot with that NTFS partition.  Like I said before, my guess would be that literally hundreds of thousands of people have dual-boot (Windows - Linux) systems using NTFS (or FAT32) partitions in similar manner to what you are trying to do.  I've been fairly active on Linux forums for the past couple of years and I've never seen this happen before.  I've done searches to try and find others with that problem and came up empty.  At this point, I'm completely stumped!  I have no idea what could be wrong.

I do have an old laptop drive with Windows 7 on it that I plop into one of my laptops once a year.  If I have the time, I'll put it in and hook up the other drive in an external enclosure and install LL to it.  That will be an almost identical situation to yours.  I'm 99.9% sure that there will be no problem booting into it.  Check back in periodically over next few days -- I'll post results when I get chance to run experiment.
