• - Solution 1: change partition type ID with a powerful utility
• - Solution 2: set partition type ID via Diskpart

Most computer users may be familiar with partitions and partition types. Actually, there are five partition types: primary, extensible firmware interface (EFI), extended, logical, and Microsoft Reserved (MSR). How about partition type ID? It is a byte value intended to specify the file system a partition contains and/or to flag the special access method used to access the partition.

For MBR disks, the value for the type field is in hexadecimal form. Following are the frequently-used type IDs for MBR-based partitions:

● 0x01 FAT12 ● 0x04 FAT16, less than 32 MB ● 0x06 FAT16, greater than 32 MB ● 0x07 NTFS ● 0x0B FAT32, used by DOS & Win95 ● 0x0C FAT32 using LBA mode to access to FAT32 partition ● 0x0E FAT16 using LBA mode to access to FAT16 partition

For GPT disks, the value for the type field is a long string. Recognized GUIDs include:

◆ EFI system partition: c12a7328-f81f-11d2-ba4b-00a0c93ec93b ◆ Basic data partition: ebd0a0a2-b9e5-4433-87c0-68b6b72699c7 ◆ Learn more…

Why would someone like to change a partition type ID? Actually, changing type ID is a good way to prevent the system using or initializing partitions. Read on to find out how to change partition type ID in Windows 10/8/7 efficiently.

How to change partition type ID in Windows 11/10/8/7 easily?

Here I’m going to show you two efficient solutions to change partition type ID in Windows 11/10/8/7. You can set partition type ID in Windows 11/8/7 with the same methods.

How to change partition numbers?

• Thread starter pirc
• Start date Feb 7, 2016
• Feb 7, 2016

So I make a clone of my C: drive with the Win 10 OS onto an ext drive which had one partition of backup files. Obviously, Macrium left the original partition as Partition 1 and placed the OS as Partition 2 and 3 (3 being system reserved from the C: drive). How can I reorder these partitions so that Partition 1 is OS, 2 is System reserved, and 3 is the original file backup partition. Is a there a utility is disk part or something else I can use for this? Thank you!

First off Windows doesn't boot from an external drive. In case of disaster, you boot with your Macrium Boot Flash, then tell Macrium to restore whatever partition of interest from the external, you just click-select it, and then highlight your Boot partition (which is now sick), and Macrium will bring the backup over and replace entirely over the sick partition. <Answer deselected by moderator at OP request>

If my ssd fails and I need a new one I can clone the clone copy from the HDD ext onto the new ssd rather than reloading and clean installing and then setting up every single program.

Your original post worried about a partition number, I hope my initial response told you, partition number not a concern. Now you have additional new concerns which I will reply hoping am not interpreting your new request incorrectly. Say you Boot partition is C: and there you have your OS and also installed your Apps there. A Macrium Image backup copies EVERYTHING in C: so no, you don't have to re-install your Apps. Your OS, with all its settings intact and the installed App will appear EXACTLY as it was the day you performed this image backup. Now as some people do, they install OS on C: but they have a small SSD and install their Apps on D:, then in order for you to be able to restore EVERYTHNG WITHOUT RE-INSTALLING ANYTHING, then your need to Macrium image backup C: as well as D: I dunno whether Macrium has the ability to backup 2 partitions as 1, that I haven't tried.

One of those things is a "boot partition" flag which tells the BIOS which partition to use to boot the machine. So partition number isn't a factor. Some utilities allow you to set or clear the boot partition flags so that can cause problems if you don't do it correctly. You could have no boot partition or you could have multiple boot partitions. In the latter case it will boot from the first partition that it finds that has the boot partition flag set. It doesn't sound like that will be a problem for you since you are using backup software. Just to clear up one other thing: drive letters (C:, D:, etc) are logical drive identifiers that are assigned at boot time to partitions by the OS. One physical drive with multiple usable partitions will have multiple drive letters assigned that access those partitions. It can get confusing when you refer to a drive letter as the physical drive. Physical drives have numeric identifiers (0, 1, 2, etc.) that are assigned by the BIOS at boot time as it finds them. Typically this is in the sequence of the data ports, i.e. SATA_1, SATA_2, SATA_3, etc. It looks for fixed media (SSD, HDD) first, then removable media like CD/DVD, USB, floppy disk, etc. Here are some scenarios: SATA_1->SSD->drive 0->only one partition=C: SATA_2->HDD->drive 1->only one partition=D: SATA_3->CD/DVD->drive 2->E: SATA_1->HDD->drive 0->two partitions=C:, D: SATA_2->HDD->drive 1->only one partition=E: SATA_3->CD/DVD->drive 2=F: SATA_1->SSD->drive 0->only one partition=C: SATA_2->HDD->drive 1->two partitions=D:, E: SATA_3->CD/DVD->drive 2=F: USB=G: (note: when you insert a USB drive after boot it is assigned the first unused drive letter by the OS) Technically speaking, an external hard drive is removable media since it can be unplugged or powered down at any time. Floppy drives are pretty rare these days but all early DOS machines had them and drive letters A: and B: are reserved for floppy drives. That's why the other logical drives start at C:

Changes the partition type field for the partition with focus. This command doesn't work on dynamic disks or on Microsoft Reserved partitions.

This command is intended for use by original equipment manufacturers (OEMs) only. Changing partition type fields with this parameter might cause your computer to fail or be unable to boot. Unless you are an OEM or experienced with gpt disks, you should not change partition type fields on gpt disks by using this parameter. Instead, always use the create partition efi command to create EFI system partitions, the create partition msr command to create Microsoft Reserved partitions, and the create partition primary command without the ID parameter to create primary partitions on gpt disks.

• Other than the limitations previously mentioned, DiskPart doesn't check the validity of the value that you specify (except to ensure that it is a byte in hexadecimal form or a GUID).

To set the type field to 0x07 and force the file system to dismount, type:

How to Change Partition to Primary Using Diskpart

Primary partition vs logical partition.

Before learning how to change logical partition to primary using diskpart command line, it is necessary to understand what a primary partition and a logical partition are.

Primary partition: It is a hard disk partition generally used to install the Windows operating system or store files necessary for operating system startup. Only the primary partition can be set as the active partition to complete a series of operations such as handover of startup tasks with the BIOS to boot the system. MBR disks can have up to four primary partitions, and GPT disks support 128 primary partitions.

Logical partition: A logical partition is an MBR hard disk partition created in an extended partition. It cannot be set to active status, which means that it cannot be used to boot the system. Logical partitions are generally used to store personal data.

how to renumber partitions

Dear Sir/Madam

a friend of mine has UEFI windows 10 21H2,

disk0 partitions layout were System , MSR , Windows , Recovery , "D" Partition , "E" Partition,

Recovery was Partition number 4, "match location sequence"

He asked me to reduce windows partition size from 2 TB to .5 TB, I did that with third parity program AOMEI,

AOMEI made the changes and for unknown reason changed Recovery partition ID, So System didn't recognize the partition as a recovery partition,

I deleted the partition, and recreated again with the correct parameters and reconfigured Recovery environment successfully,

but recovery partition became number 6, it's located after windows partition number 3 but became number 6,

UEFI layout became System (1) , MSR (2) , Windows (3) , Recovery (6) , "D" (4) , 'E" (5),

is there any way to get back number 4 for Recovery ? without losing data for windows partition , "D" partition and "E" partition?

In brief how to renumber partitions according to it's correct sequence?

Hi ao1793ZQ,

Welcome to post in Microsoft Community. I'm Mosken, let me help you figure it out.

According to your description, I knew that after you change the size of your system partition, the partition numbers on your disk are messed up. Is that right?

First, can you take a screenshot of your current interface in Disk Management , and only send the relevant information to me in the next reply, so as to solve the problem faster and better.

I tried to reproduce your problem and found that ordinary Windows partitions (such as system partition, D drive, E drive) do not have the numbers you mentioned, only in the Windows boot partition and reserved partition will there be disk 0 partition 1 , disk 0 partition 2 , etc. numbering. Therefore, your disk status may not be the default of Windows, and we cannot make specific analysis and provide further technical support for the operation results of third-party software, so please provide us with more detailed information.

And I'm sorry that for now there is no solid solution to this issue , and changes in partition numbers will not necessarily affect your system . 

Below are some links related to Windows disk partitions, I hope they will help you.

How to Use DiskPart Utility in Windows

Format, resize, extend and manage your drives

The Disk Management Tool is a useful, effective tool for managing your Windows disks and partitions, but it isn’t as powerful to use as Diskpart. This command-line tool lets you delete, create and modify partitions on any hard drives or USB storage your PC can detect.

We’d recommend using the Disk Management Tool for most situations, but if Windows isn’t starting up properly, or if you prefer to use the PowerShell terminal , Diskpart is the perfect alternative. Here are some of the more common Diskpart commands to help you learn how to use Diskpart effectively.

How To Use Diskpart

If you want to use Diskpart, you need to open up a Windows command line or PowerShell terminal. Diskpart is a destructive tool, so you’ll need to open a terminal window with the right administrative privileges.

• To open Diskpart in Windows, right-click your Windows Start menu button and click Windows PowerShell (Admin) .

• In your admin-level PowerShell terminal (or similar Windows command line), type diskpart and hit enter.

• The Diskpart tool will launch within the window, ready for you to use. Type exit at the “DISKPART>” prompt and hit enter once you’ve finished using it.
• Diskpart is also available for users booting into the Windows Recovery Environment, available when you boot your PC using the Advanced Startup mode in your Settings > Windows Update & Security > Recovery menu.
• Click Restart Now to boot to WinRE.

We’ll explore some of the most common Diskpart commands in this article, but if you want to quickly see the full list of available Diskpart commands, type help at the “DISKPART>” prompt and hit enter.

Listing Existing Hard Drives, Volumes & Partitions

Once Diskpart is open, the first thing you should do is check the current layout of your hard drives and attached storage.

• At the “DISKPART>” prompt, type list disk and hit enter. This will list all of the available storage drives (including hard drives, USB storage, SD cards, etc.) that your PC can currently detect.

• Starting with the number zero, Diskpart will list any detected disks. You’ll need to remember the disk number (for instance, “0” for your Windows hard drive) to use with future Diskpart commands.
• Along with your list of disks, you can also ask Diskpart for a list of detected volumes. At the “DISKPART>” prompt, type list volume .

• Diskpart can also let you list individual hard drive partitions (some of which may match the volumes listed with the “list volume” command). You’ll need to select a hard disk first with the list disk command.
• At the “DISKPART>” prompt, type select disk followed by the disk number (for instance, select disk 0 ). Diskpart will confirm that the disk is selected at this point.
• Once a disk is selected, type list partition . This will list the current partitions on your drive. You’ll be able to delete or modify these partitions from here, using the partition number in a later Diskpart command.

Deleting a Hard Drive Partition Or Volume Using Diskpart

A hard drive (disk) is separated into partitions, which are often the same as listed volumes. If your hard drive is separated into several partitions or volumes, and you wish to delete one, you can do that using Diskpart commands.

• Select your hard drive using select disk. 
• At the “DISKPART>” prompt, type list partition , then select partition # , replacing # with your partition number.

• Once a partition is selected, type delete partition . Diskpart will confirm whether or not the partition has been deleted afterward.
• You can also delete disk volumes directly if you’d prefer.  Type list volume , locate your chosen volume number, then type select volume # , replacing # with your volume number.

• Type delete volume to delete the volume completely. Diskpart will confirm if the command was successful or not afterward.

Wiping a Hard Drive Completely Using Diskpart Clean

Rather than removing individual volumes or partitions on a drive, you can wipe a hard drive completely using the Diskpart clean command. You can also use this command if you’re looking to wipe a USB flash drive, ready for formatting.

You won’t be able to do this on your system drive (nor would you want to!) unless you’re using Diskpart on a Windows installation

• At the “DISKPART>” prompt, select the disk you wish to wipe by typing select disk # , replacing # with your disk number. If you don’t know your disk number, type list disk first.

• If you’re sure you want to wipe the disk completely (deleting all drive volumes/partitions), then type clean and hit enter. You won’t be asked for confirmation, so be sure you wish to do this before you begin.

• Diskpart will confirm that the drive has been “cleaned”, ready for new partitions to be created.

Creating & Formatting New Hard Drive Partitions  

With a “clean” drive, you’re ready to create a partition in the free space using the Diskpart create partition command. You can then format that new partition with a Windows-friendly file system like NTFS or FAT32 using the Diskpart format command.

• Start by selecting your chosen disk with select disk #, replacing # with your disk number (and using list disk to find your disk number, if you don’t know.)
• With your disk selected, type create partition primary to create a partition using the entire space on that drive.
• If you want to create a partition to take up only some of the free space (letting you create more than one partition), type create partition primary size=X instead, replacing X with the partition size, measured in megabytes (for example, size=1024 for 1GB of space).

• Type list partition to make sure that your new partition is listed, then type select partition 1 to select it. Mark the partition as active by typing active at the “DISKPART>” prompt. This is necessary if you want to use it as a bootable drive.

• To quickly format the drive with the NTFS file system, type format fs=NTFS label=Y quick. You can replace Y with any label you’d prefer to use.

• Once formatted, Windows will likely assign a drive letter automatically. If it doesn’t, type assign letter Z , replacing Z with a free drive letter.

Extend a Hard Drive Volume

If you have an existing hard drive volume that doesn’t take up all of the free space on a drive, and you wish to enlarge it, Diskpart commands allow you to do that.

• Type list volume to list all the available volumes on your PC, then type select volume # , replacing # with the volume you’re looking to extend.
• Type extend to expand it to the maximum size available. Diskpart will confirm whether or not the extend command has worked correctly.  Confirm the size of the volume has increased by typing list volume for a second time afterward.

Diskpart has other options available, as the help command briefly explains. If you need further information on how to use Diskpart, Microsoft has further Diskpart support information available.
