The selected disk has an MBR partition table. Deal with the error message “Windows cannot be installed to this disk. Need more than 4 primary partitions to store different types of files.ģ. Make the fullest use of a large hard drive which is over 2TB and don’t want to waste the rest space surpassing 2 TB.Ģ. Since GPT comes with the mentioned-above advantages over MBR, you might need an MBR to GPT converter to change partition style from MBR to GPT in Windows 10/8/7 in the following cases:ġ.

By contrast, the GPT disk saves multiple copies of data across the disk, so it is more robust and can be recovered when something goes wrong. ③Data Storage Method: On the MBR disk, the partitioning and boot data is stored in one place, so if the data is overwritten or corrupted, the enter disk will be unusable. On a GPT disk, you can create 128 primary partitions at most. To create more partitions, you need to make the 4th partition as an extended partition firstly, and then you can create more logical partitions. ②Primay Partition Number : On the MBR disk, you are allowed to create up to 4 primary partitions.

When your MBR disk is over 2TB, the rest space will be shown as unallocated space in Disk Management and cannot be used. ①Disk Size: MBR disk only supports up to 2TB in size while GPT disk could support up to 18EB in the capacity. They mainly differ in the disk size, partition number limitations, etc. MBR is an old hard disk style to manage the partitions while GPT is the latest standard for disk partition management. MBR (Master Boot Record) and GPT (GUID Partition Table) are two different partition styles for hard disks. In this article, we will explain the difference between GPT and MBR and introduce great free MBR to GPT converters. Now, Microsoft announced that upgrading from Windows 10 to Windows 11 via the 'Check for Update' requires the UEFI boot mode and GPT boot disk. That is to say, we need to initialize the new hard drive to either MBR or GPT before using it for data storage.

Three free MBR to GPT converters you can try in Windows PCĪs we all know, when setting up a new disk on a Windows computer, we will receive a message saying “You must initialize a disk before Logical Disk Manager can access it”.
