How to Partition using Command Prompt?

Hard disks can be partitioned to run separate operating systems on the same disk, or to break down a disk into manageable chunks for storage. Partitioning is performed on a new or reformatted disk. These instructions describe using FDISK for PCs using DOS 3 or later.

Instructions :
STEP 1: Start the computer in DOS. The screen will show the C:/ prompt.
STEP 2: Type "FDISK." The partition window will appear with menu options.
STEP 3: Enter 5 if you're partitioning a second drive, and select the drive; otherwise, skip to the next step.
STEP 4: Enter 1 (Create DOS Partition or Logical DOS Drive).
STEP 5: Enter 2 (Create Extended DOS) to create a partition.
STEP 6: Enter N when the program asks if you want to use the maximum available size.
STEP 7: Designate the amount of disk space to allocate to the second partition (the partition will be assigned the next drive letter).
STEP 8: Type a name for the new partition and press Enter. The partition menu will appear.
STEP 9: Repeat steps 5 through 8 to create additional partitions.
STEP 10: Press Esc to exit the partition command.
STEP 11: Format the newly created partitions (see "How to Format a Hard Drive").
