  Well, re-FDISKing the drive will lose all of your existing data on
it.  Whether that's considered safe could depend on how much use
you've made of the drive so far.

  You *might* be able to avoid that using Partition Magic, or
something similar.  I'm not positive that it can copy a primary
partition to a logical volume, but once you create the volume you
could use xcopy for that step.[*]  You should back up the data
anyway, but at least this can save you the hassle of restoring it.

  The only restriction that's likely to apply is that only primary
partitions can be bootable.


[*] The steps are something like:

1.  Shrink existing logical drives, and move them up against the high
end of the extended partition.  Create a new logical drive at the
start of the partition (and format it, I believe).

2.  xcopy the primary partition to the new logical drive using
appropriate options (depending on OS).

3.  Back to PM; delete primary partition, expand extended, and
resize/move logical drives to fill space.
