You can use a tool which shows these records , e.g.,
http://www.bttr-software.de/bootmgr/  (or one of the more sophisticated
tools available on the Web, look for, e.g. Ranish).

Right.

Not FAT16! Extended partition is a 'container' that keeps logical
partitions (also known as logical drives) INSIDE.

This cannot work (see above).

If you want to make a second primary DOS partition with DOS FDISK and
some hex editor only, you first have to hide your current primary
partition (by, e.g., changing it's identifier from 06 hex to 16 hex).
Then you can add another primary partition with FDISK (it won't recognize
type 16 hex as a DOS primary partition, and won't complain that there
would be already one); of course, DOS won't even boot from type 16 hex,
it will be inaccessible. Finally, unhide your original primary partition
(change it type from 16 hex back to 06 hex). After next reboot, you'll
see two primary DOS partitions; remember to give them some labels,
because drive letter ordering in case of multiple primary partitions
depends on DOS version, and can easily get confused.

Hope it helps,
