Deleting and Creating the Primary Partition
Since
this computer has been operational, it already has a partition. You are going
to first delete the existing partition and then create a new partition.
- For the hard drive to function it needs to have a partition. The partition
takes the space on the disk and makes it so it can be formatted.
- The partition your hard drive uses to create the bootable portion of the
disk is called the primary partition.
- Since you are at the A:> prompt any DOS command you type in will need
to come from the floppy in the "A" drive. In the
previous
assignment you created a bootable floppy with three additional files on it.
FDISK was one of those files. It is a DOS utility used to create partitions
on hard disks.
- Type FDISK at the A:> prompt and press Enter.
- The first thing you are asked is if you want to allow for large drives.
Earlier in the history of computers hard drives where not very big (storage
space). If you had a 1GB hard drive you had a lot of storage capacity. However
as files and programs became more sophisticated larger drives became essential.
DOS could not create partitions over 2 GB in size. Now there is no piratical
limit on the size of your partition. So to accommodate for larger drives the
FDISK utility was modified so larger partitions could be created. This question
is asking you if you want to allow for partitions over 2 GB.

- Answer Yes and press Enter.
- The main FDISK options menu comes up. Notice you have four choices.

- Type 4 and press Enter. This will allow you to see the existing partition
on the hard drive. In most cases you will have only one partition. See display
screen. In the example there are two partitions.
- Press Esc to go back to the main menu.
Since you already have a partition on the hard drive you are going to delete
the existing partition first.
It is important to note that FDISK can be very dangerous
to use. Once you delete the partition all data on the hard drive will be
gone forever.
- Type 3 and press Enter. This takes you to the FDISK Delete Menu.

- You have four choices. You probably found, when you displayed the partition
information, that you had only one partition. This is your primary partition.
Type 1 and press Enter to delete the primary partition.
- You will be asked for three pieces of input. First which partition. This
is the partition number. It is probably 1. Type 1 and press Enter.
- You will be asked for the Volume Label. Look at the top of the screen to
see what the volume label is. Many times it is blank. Type the volume label
name and press Enter. (If the volume label is blank just press Enter).
- You are now asked if you are sure. This is the point of no return. If you
really want to delete the partition and lose everything on the hard drive
then type Y and press Enter.
- The primary partition is now deleted.
- Press Esc to return to the main menu.
- It is now time to create a new primary partition. Type 1 and press Enter.
- You are now at the Create Partition screen. You have three choices. Since
you don't have a primary partition you need to create one. Type 1 and press
Enter.

- It will create the partition. When it is done it will ask you if you want
to make the partition active. This is asking you if you want this partition
to be able to be bootable. You do. Type Y and press Enter. It will complete
the process.
- You will get back to the main menu. Press Esc to exit.
- You will need to restart your computer. Make sure the bootable floppy is
still in the drive.
