Removing an operating system from the hard disk

You may find that you no longer need one of the operating systems installed on your hard disk.




If you want to delete an operating system, use the appropriate version of fdisk. To delete a UNIX partition, you must use the UNIX system version of fdisk. To delete a DOS partition, use fdisk under DOS.



To delete an Extended DOS partition, you must delete all logical drives on that partition using fdisk. Deleting the partition removes the contents of that partition and leaves unallocated space.

You can then reallocate that space by either adding another UNIX or DOS partition, or enlarging an existing partition. Enlarging a partition requires reinstalling the operating system and (for a UNIX partition) remaking the filesystem on the partition using divvy(ADM).
