How to use DOS

To partition your HDD in DOS, you need to use FDISK command. It is one of the DOS utility files that comes with the DOS or MS Windows.
Windows start-up disk has it too.

Here are the steps:

1. Run FDISK from the location where it is stored.
2. Click on "yes" for large disk support.

3. choose the # with primary dos partition.
(This is the partition where your Operating System will be installed) Usually C:\>

4. The other drive will be your extended dos partition. Usually D:\>, e:\>, etc. It depends on how many partitions you're gonna have.

5. Create the partition and determine the size of your partition.

6. Choose the HDD and the size for your primary dos partition. Preferably 4Gb for WinNT and Win 2000.

7. Format the Drive after the partition has been created.

8. Do the same for extended Dos partition if you have any.

I'm giving these steps from top of my head. There may be some steps that I might have skipped, if any. However, FDISK program is fairly self-explanatory and pretty easy to use.
First time users shouldn't face any problems using it.

Use the 8 steps from the previous answer, but add another step.

9. Create a logicical partition (within your extended partition) and select maximum size.
