Turn to 3rd party format tool to create primary partition. When you try to create second partition on removable disk, here I recommend you a third party format tool – AOMEI Partition Assistant Standard. It allows you to create two or multiple partitions on SD card or USB flash drive stick without any efforts. Free download, install. “Partition Wizard cannot create a partition at here. There are no free MBR slots on the disk” Dalam kasus ini saya berasumsi hal ini terjadi karena mungkin sudah terdapat 4 tipe Primary pada partisi sebelumnya, sehingga jika saya ingin membuat partisi yang ketiga supaya bisa dibagi, maka saya perlu merubah partisi yang ke-4 (empat) menjadi tipe Logical. Computer architecture allows each hard drive to have no more than four primary partitions (the other partitions are extended partitions). Because the Ghost Virtual Partition is implemented as a primary partition, you see this message when the disk is using all four primary partitions and does not have an available slot for the virtual partition.
- why you couldn't create a new partition or locate an existing one
- methods of how to fix it
- how DiskInternals can help you
Are you ready? Let's read!
“We couldn't create a new partition or locate an existing one. For more information, see the Setup log files”
Most often, this error appears when installing an operating system on a new disk (HDD or SSD), or after preliminary steps to convert between GPT and MBR and change the partition structure on the disk, or during formatting.
The main reason for the impossibility of installing Windows 10 after the indicated message that it is not possible to create a new partition is the existing partition structure on the hard disk or SSD, which prevents the creation of the necessary system partitions with a bootloader and recovery environment.
What issues can be causing this?
First, going by the name of the error, it is clear that creating a new section, as well as searching for an existing section, is impossible. The same problem can be attributed to SSD or RAID.
There may also be problems when installing the system from a USB flash drive, as well as when creating a dual boot or a new BIOS or GPT partition.
As you can see, the message “we couldn't create a new partition or locate an existing one” can mean many things, but it always means something bad could happen. Therefore, read on to solve this problem.
Method 1. Restart the PC/laptop
This may be a single computer failure, so start by rebooting the PC. After that, some users can calmly create partitions without any obstacles. Therefore, be sure to try this, and you may be lucky.
Method 2. Reconnect the external device
![Cannot Cannot](/uploads/1/3/4/0/134071846/815834582.png)
Try connecting external devices to other ports and restarting the interrupted process. If all else fails, reconnect the USB flash drive into the original slot; perhaps now it will work properly.
If not, method 3 can help.
Method 3. Turn off all external devices
Now try to create a partition without any external devices, if possible. Sometimes it’s flash drives that slow down the whole process. If this solution did not help you, do not panic; there are a couple more excellent and useful tips.
Method 4. Run diskpart
This utility is available during the installation of the operating system.
During the download, click on Restore, then click on Advanced. The available actions will appear on the screen; select Command Prompt (type “diskpart” in this window and press Enter).
Then you need to type these commands:
“select disk (1/2/3)”, depending on which disk is needed. You need to enter this without brackets. Then press Enter.
disk (1/2/3) clean - press Enter key
disk (1/2/3) create partition - press Enter key
disk (1/2/3) active - press Enter key
disk format (1/2/3) fs = ntfs quick - press Enter key
disk (1/2/3) assign - press Enter key
Then try the installation again.
This should help.
Method 5. Inactive partition
This is also possible with the diskpart command. After that, you need to enter several commands:
list disk
select disk 1 2 3 (select the desired one)
list partition.
select partition 1 2 3 (select the one you want)
active
Each command is followed by Enter.
Then reinstall the OS.
However, remember, if you are not a very experienced user, then carefully follow these steps or ask for the help of a more experienced friend.

Partition Wizard Reports No Free MBR Slots Error
MiniTool Partition Wizard is a highly competent partitioning toolkit that both average users and experienced users have little difficulty to cope with, and is always a good choice when you're doing hard drive management without killing data. Partition Wizard consists of five kinds of licenses and supports all latest partition technologies such as Windows dynamic disks and GPT disk, as most programs of its industry do.
Although Partition Wizard offers user-friendly interface, many users may get confused when encountering some error prompts, like Error Code 4 and Error Code 40. What we are going to talk today is one of the hot discussions: Partition Wizard reports No Free MBR Slots Error.
Note: In Windows Disk Management, this error is shown as 'the operation will convert the selected disk(s) to dynamic disk(s)…' or 'the disk already contains the maximum number of partitions' as showing below:
This post tells what to do if you can't create partition in Windows 8.
How Does This Happen
Before getting into the main part, we would like to explain the related. In Partition Wizard, No free MBR slots occurs on an MBR disk, which is a phenomenon indicating that the operation you are carrying out will break the rule that there should be four primary partitions or three primary partitions plus one extended partition at most on an MBR disk (extended partition can be further divided into many logical partitions). Thus, Partition Wizard won't go any further.
However, when seeing this error message, you don’t need to get worried, because Partition Wizard also offers several ways to help you out.

How to Remove No Free MBR Slots
Chapter 1: Partition Wizard Can't Create Partition - No Free MBR Slots
It is my hard disk original state:
Local Disk C:450 GB
RECOVERY D:15 GB
But system has 2 others as:
SYSTEM 199 MB
HP_tools 104 MB
I want to create at least 1 other local disk, so I resized (Cto 120 GB and 330GB volume remained as free.
When I clicking on an Unallocated space and click on 'create' reply this error:
'Partition Wizard cannot create a partition at here. There are no free MBR slots on the disk.'
Now I don't know how to make MBR slots available. --from Tomshardware
While creating a new partition, 'No free MBR slot' may emerge in the following two scenarios:
Scenario 1: There are four primary partitions on the same disk already.
As the screenshot shows below, there are already four primary partitions on an MBR disk, Partition Wizard can't create a new partition and gives out the error message.
Cannot Create Partition No Free Mbr Slots Free
If you require more than four partitions, you need to convert the primary partition followed by unallocated space to logical partition, then use the unallocated space to create another logical partition. In this way both logical partitions are contained in an extended partition, forming the partition layout of three primary partitions plus one extended partition.
Step 1: Click on the primary partition to be converted (in our case, it's H:) and employ 'Set Partition as Logical' from the Operation menu. Then click 'Apply' at the toolbar to finish this conversion.
Step 2: After conversion, you can normally employ 'Create Partition' feature on the unallocated space. In the pop-up window, you can specify the parameters including partition label, drive letter, file system, cluster size and partition size of the new partition. Remember to tick 'Apply' in the end.

Useful tips after you create a new partition:
- How to convert file system without formatting?
- How to change cluster size without losing data?
Scenario 2: There are three primary partitions plus one logical partition, but the unallocated space is far away from the logical partition.
Another case is that if there are already three primary partitions plus one logical partition on the hard drive, and the unallocated space is not adjacent with the logical partition, Partition Wizard won't allow creating a partition and reports 'No free MBR slots'. (Screenshot attached)
To resolve this problem, you need to convert a primary partition to logical before creating a new partition with the unallocated space.
Note: In this scenario, the primary partition to be converted to logical should be either partition that is adjacent to the logical partition, because extended partition should be included together.
Step 1: Click on the primary partition to be converted (in our case, it's G: or H:, and we choose H:) and select 'Set Partition as Logical'. Click 'Apply' to finish this conversion.
Step 2: After conversion, you can successfully create a new partition with the unallocated space.
For a more intuitive tutorial, you can refer to this video:
Chapter 2: Partition Wizard Can't Split Partition -No Free MBR Slots
Apart from creating partition, another situation that 'No free MBR slot' may appear in Partition Wizard is during the process of splitting partition. Let's see a real life example:
Hello,
Problem: splitting one big partition in two smaller ones fails When I try to split my 95GB partition into two smaller parts, minitool's partition wizard tells there are no free mbr slots, I have no idea how to get free mbr slot.
But the last time I use partition wizard it did help me split one another partition.
Can anybody help me get across this? Or I have other choice? Thanks!
While splitting a new partition, 'No free MBR slot' may emerge in the following two scenarios:
Scenario 1: There are already four primary partitions on the same drive.
If there are already four primary partitions on the same drive, Partition Wizard can't split partition. Because if one of them is split into two parts, there would be five primary partitions or four primary partitions plus one extended partition on an MBR disk - not allowed. (Screenshot attached):
If no empty slot in MBR partition table occurs in Partition Wizard while you are trying to split one of the four primary partitions, the way to overcome this is to convert the primary partition you would like to split to logical partition at first and then carry out partition division. Take splitting partition H: for example.
Step 1: Right click on partition H:and select 'Set Partition as Logical' from Operation menu. Then press 'Apply'.

Step 2: Now the target partition is shown as logical partition. Click on it and choose 'Split Partition' from Operation menu. Then drag the slide button to set the partition sizes of the original partition as well as the new partition before you click 'Apply'.
Scenario 2: When there are three primary partitions plus one logical partition on a hard drive, Partition Wizard can't split primary partitions except the one closely located in front of the logical partition.
The reason?
By default, when splitting a primary partition, MiniTool Partition Wizard will divide it into two parts: the former part keeps primary, and the latter part turns to logical. However, while splitting a logical partition, both parts are kept as logical. Thus, if there are already three primary partitions plus one extended partition, splitting a primary partition closely located in front of the logical partition can put the logical partitions together, but splitting the rest primary partitions will leave the logical partitions apart from each other, that is to say, there will be more than one extended partition - not allowed.
To make it clearer, we draw a table to show the words.
Disk Layout | Primary | Logical | Primary | Primary |
Divisible | YES | YES | NO | NO |
Disk Layout | Primary | Primary | Logical | Primary |
Divisible | NO | YES | YES | NO |
Disk Layout | Primary | Primary | Primary | Logical |
Divisible | NO | NO | YES | YES |
In this case, you need to select either primary partition adjacent to the logical partition and set it as logical partition before splitting. Take splitting partition H: for example.
Step 1: Click on the primary partition(in our case, it's H:) to be converted and select 'Set Partition as Logical' from the Operation menu. Then click 'Apply' to execute this change.
Step 2: Now click partition H: and select 'Split Partition' from the menu. After confirming the partition sizes of the original partition and the new partition, you can press 'Apply' to end the operation.
Note:- Please do not set a system partition as logical, for this operation may cause your system unbootable.
- To split a partition, the minimum partition size should be no smaller than 200MB, otherwise you will receive another error message: Not Enough Free Space.
Chapter 3: How to Avoid No Free MBR Slots Error
Now you know how to solve this MiniTool Partition Wizard error. In fact there is another way that can solve this error once for all, that is to convert MBR disk to GPT disk. The reason of doing this is that in GPT disk differs from MBR disk in many aspects:
- In Windows, all GPT partitions are treated as primary partitions.
- In Windows, the maximum partition number of GPT disk reaches up to 128 - a rather large number for you to partition a hard drive without worrying about 'no empty slot in MBR partition table'.
- GPT can recognize disks larger than 2TB, while the upper limit for MBR is 2TB.
- The GUID partition table is automatically backed up to resist virus infection or misoperation, which is a deficiency for MBR.
Please take care that the Free Edition is able to convert non-system disk form MBR to GPT. To deal with the system disk, use MiniTool Partition Wizard Bootable instead, in case that any accident may lead to the operating system fails to boot. Step-by-step guide is showing below:
Step 1: Right click on the disk icon of the drive to be converted, and select 'Convert MBR Disk to GPT Disk' from the pop-up window.
Step 2: You can preview this drive will be converted to GPT disk. Click 'Apply' to save this change.
The Advantages of Using Partition Wizard
After saying so much on the topic 'no empty slot in MBR partition table', you must have mastered the causes and the solutions. Now let's look away and focus on another point: since Partition Wizard gives the similar error message with Disk Management while creating partition, what is the advantage of using this freeware, does Free means Futile?
If you are a fresh user of MiniTool Partition Wizard, you may have no idea of the power of this free partition magic. Compared with Disk Management, Partition Wizard (free edition) not only gets rid of the limitation that extend volumegreyed out, but also wins out in these features:
- Create FAT32 partition larger than 32 GB.
- Directly split one partition into two parts.
- Move partition location.
