Firstly, let’s see what partition type, Primary partition and Logical partition is, if you are clear about partition type, please skip the first paragraphs and see how to convert partition between Logical and Primary without data losing.

Primary Partition Type

A Primary partition contains one file system. In MS-DOS and earlier versions of Microsoft Windows systems, the first partition (C:) must be a primary partition. Some operating systems are not limited in this way; however, this can depend on other factors, such as a PC’s BIOS. The “partition type” code for a primary partition can either correspond to a file system contained within (e.g. 0x07 means either an NTFS or an OS/2 HPFS file system) or indicate the partition has a special use (e.g. code 0x82 usually indicates a Linux swap partition).

Extended Partition Type

An extended partition is a primary partition which contains secondary partition(s). A hard disk may contain only one extended partition; which can then be sub-divided into logical drives, each of which is assigned additional drive letters. Windows allow creating at most 4 primary partitions, or 3 primary partitions and one extended partition. Extended partition could contain many logical partitions.

Why change partition type

There are many reasons why you need to change partition type between logical partition and primary partition, below are some examples.

  • In MS-DOS and earlier versions of Microsoft Windows systems, the first partition (C:) must be a primary partition. So it is impossible to set up dual boot operating system if there is no other primary partition, except that you convert an existing logical partition to primary.
  • Due to Windows limitation, you can only create 4 primary partitions at most in single MBR disk, so you are very likely to encounter this problem that you cannot create more partitions, especially for Windows 7 users.
  • In some special conditions, only primary partition or logical partition is allowed (not both), but you cannot provide partition with such type.

If you can change partition type directly from primary partition to logical, or convert logical partition to primary, it is very convenient.

    a option of set as logical isn’t available

    Please note that there are 4 primary partitions or 3 primary partition plus an extended partition at most in a hard disk. Of course there could be many Logical partitions in the extended partition.
    Not every primary partition can be set a Logical. For more details, you may contact support@www.hdd-tool.com and send your disk management, and then you’ll know which partition can be set as logical

    So without creating ANY logical partitions…. the limit is 3 or 4?

    Or 5 (more than 4) like some sites claim?

    A Logical partition is part of the extended partition.
    There is only one extended partition on a hard disk drive, but there could be ‘unlimited’ Logical partitions in the extended partition.
    If you want to get more Logical partitions, just shrink D and create more partitions. If you don’t know how to shrink, tell me :-D.

    I have a 1TB hard drive that is formatted into 1 24gb partition (C) and another full partition F. Windows 7 is installed onto the C drive and I would like it to stay that way. However, every program wants to make the C drive its home. Clearly, there is not enough space for this, I would like to make the F drive the primary drive so that everything naturally installs here. My Computer Management Tool lists both as primary partitions, with the F drive listed second. The C drive is listed as: System, Boot, Active, Crash Dump, Primary.
    Any help would be most appreciated.

    Thanks
