I have a 20 GB hard disk with one partition C. I want to create a new partition call it D and make it about 7 GB so i can store seperate files on it. I just want to know what are the steps i should take after i type fdisk (step by step). Thanks.

Exactly what are you trying to achieve? Are you trying to change the existing partition structure on your drive and keep the current operating system and files? If so then FDISK is NOT what you want to do as it will effectively wipe your drive. You will need a third party prog like Partition Magic8 to accomplish what you want and there are no guarantees even that won't stuff up your system. Before beginning anything of this nature back up your files and be prepared for a complete format and reinstal if things go wrong. Of course if that happens then you will be able to use FDISK to partition your drive the way you want. Post back and expand on your question so correct advice can be given.

just follow the instructions fdisk will give you. it will ask you if you want to use the full disk for patition c: hit no, type in the amount of bytes for c: then, go to logical drive in the extended partition, and type in the amount for the next partition, etc

Using the proper method, you will lose all your data on your drive. Have XP running normally; insert the XP system disk, the XP install screen will appear; choose Fresh Install, do NOT choose Upgrade. Next, choose the option "I want to choose the drive/partition to install into" or words to that effect; You will see a graphic representation of your Harddrive, showing all partitions. Remove them all completely, thus wiping your disk clean. Now create two partitions, One 7 gigs, and one 13 gigs. XP may automatically create a small partition (8 megs, I think) for itself-that's okay, its needed for system files. Format your partition you want for C drive in NTFS (the best) or FAT32 (not the best). Soon as the formatting procedure completes, the installation will begin. Finally, when XP is loaded and running smoothly, reinsert your XP disk again, and follow same procedure as above, only fomat and install on the remaining partition. Now when you boot up, you will be given the option of booting into XP#1, or XP#2. Okay, why did I dual boot you both with XP? Because if your main (C) XP crashes thru a virus, whatever, you can still retrieve your data because its stored on a bootable partition, namely (D) XP. And the reverse; if your Library crashes, you can pull out your data by booting into C, go into Explorer and open up your D drive and pull out the data. I have used this for years, and it has saved my hide several times. If you don't want to do this, use Partition Magic to create an extra partition, and format it in NTFS. However, I strongly suggest you practice on an old machine that "doesn't matter" if you trash the HD, because PM is a great program, but folks trash their disks using it all the time. It will react differently on different machines, so beware.
