When your files get lost after converting the disk from MBR to GPT, you can read this post from MiniTool to see how to recover lost files after MBR to GPT conversion by using the best data recovery software. Besides, in this article, we will show you how to convert MBR to GPT without losing data.

A Brief Introduction to MBR Disk and GPT Disk

Master Boot Record (MBR) and GUID Partition Table (GPT) are two partition styles. They each have advantages and are suitable for different system and partitioning needs.

Advantages of MBR:

  • When your motherboard doesn’t support UEFI boot, you can choose to boot from an MBR disk.
  • When you are using a 32-bit Windows, you need to choose MBR because only 64-bit Windows versions can boot from GPT disks.
  • When you are using an older Windows system like Windows XP, you have to choose MBR.

Advantages of GPT:

  • GPT supports more than four primary partitions (up to 128 primary partitions in Windows). MBR disk can only hold 4 primary partitions at most.
  • GPT supports disks larger than 2 TB on both hard disks and SSDs.
  • GPT is more secure and reliable than MBR. This is because the GPT disk has a built-in auxiliary partition table. Once an error is detected on the primary GUID partition, the entire partition table can be restored from the backup GUID partition header.
  • It is faster and more stable to boot Windows from a GPT disk.

For more information about MBR and GPT, you can refer to this article: MBR vs. GPT Guide: What’s The Difference and Which One Is Better.

Due to their different characteristics, many users tend to convert MBR to GPT or vice versa.

However, when you try to convert an MBR disk to a GPT disk in Disk Management or by using the diskpart command line, you need to remove all the data and partitions on the MBR disk. Yet, some users are not sure about this, so their files get lost after a disk MBR to GPT conversion. Here you can see a true example:

When I curiously selected "create a new partition table" and the new type of it is GPT, it pops up a warning message that "I may loss all...", but I still clicked yes, as I thought all the operations on the disk would be listed in a window and waited for my confirm. But no, the creation just started immediately, and all my data and partition got lost now. How to recover the lost data and partitions after the conversion is finished?
