I disagree with you. Here is my partition table for one drive. I have windows and 4 distros of linux going just fine. The order is reversed and I did it with linux fdisk, much like he did with gpart. You will see that hda7 and hda8 are out of order.

But linux fdisk variants will not run a mkfs, so use one of those So fdisk/cfdisk/sfdisk : whichever one you like the best, but don't forget to read manpages first if you don't know the programs yet.

It is possible to have any partitiontype inside any extended. (don't put another extended in though) Whether it's usable or not depends on the OS that reads the table. Putting a windows ID inside a linux extended is also possible. Linux won't care, windows wouldn't be able to find it though.

The overlap should not be possible, but poor partitioning programs exist. Normally you wouldn't be able to create such a table though.
