Partitions

Hello everybody, I tried installing w2k a few days ago, and something, during installation something messed up my partition table. Nothing worked after, so, I used yast1 to make 3 logical partitions, and used yast2 to install suse. When I tried to use fdisk I saw that I did not have any logical partitions anymore? I don't exactly know the difference between the kinds of partitions. Should I care what kind of partitions yast2 made? thanks in advance, Jan-Willem
