Change Partition Type between Logical and Primary without Data Losing

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 change partition type between logical and primary without data losing directly.

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. 0×07 means either an NTFS or an OS/2 HPFS file system) or indicate the partition has a special use (e.g. code 0×82 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, 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 time saving and more convenient.

  1. 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@hdd-tool.com and send your disk management, and then you’ll know which partition can be set as logical

  2. i have 5 partition (c) 20 gb, (d) 20 gb, (e) 40 gb, (f) 40 gb, (g) 40 gb. in my drive. in (C) Partition, I have Window XP & In (D) Partition, I have Window 7, & Other three have My Work data. Now I want to Delete both (c) & (d) partitions & merge It & want to installed Window 7.

  3. mo:

    hi
    my HDD is tow partitions C/ 20 GP primary D/139 Logical
    how i make that partition (D) extended
    thx

    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.

  4. 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

  5. Hi,

    I have the “HP Pavilion P6-2370ef” with Windows 8 pre-insalled. The manufacturer monopolises the full disk with preinstalling software into four different primary partitions.

    Because I can’t access the scanning functions of my “HP PSC 750” (I could do this in Windows XP). I would like to install WinXP along with a linux distro on different logical drives, along with my Windows 8 primary partition converted to an extended/logical partition.

    I tried to change the owner settings of windows 8 before trying to run partition managers, thinking it may change the security settings of Win8, but that did not help a bit.

    I’ve tried doing this with a few different software (AOMEI Partition Assistant, GParted, Easus Partition Master). I could have tried others, but I think I won’t be able to.

    I suppose there is some kind of security setting to be changed, either in the bios/motherboard, or elsewhere.

    Can anyone help me?
    Thanks

  6. Due to Windows limitation, you can only create 4 primary partitions at most

    of course this is strictly speaking not a Windows limitation but a limitation due to the size of the master boot record.
