How to Recover Lost Data after Disk MBR to GPT Conversion

Can I Recover Lost Data After Disk MBR to GPT Conversion

"I tried to install a new application on my computer, but the application requires GPT for installation and my disks are MBR. As I can't convert the system disk, so I made the change on the second hard drive.

By following a tutorial guide online using Disk Management, I found that the partitions on the second disk vanished from my computer after the conversion. I have stored quite a lot of important data and files in that partition. Can I recover lost data after disk MBR to GPT conversion?"

Cause of partition and data loss due to disk conversion

Some users don't know how their partition and data get lost after disk conversion - MBR to GPT or GPT to MBR. Actually, it's a common issue. As you can see from the below image, the conversion option is not available in Disk Management:

You have to delete all existing partitions to make the conversion option available. This is why you can't see all existing partitions and saved data. So how to get back all lost data and partitions? Read on, you'll find reliable solutions on this page.

Solution 1. Restore Lost Data and Create Partitions on Converted Disk

Stop using the computer hard drive once you lost data after disk conversion (MBR to GPT or GPT to MBR). This will help you to protect hidden partition data or lost data from being overwritten by new data. Then go through the guidelines here to bring your disk partition with all lost data back:

# 1. Restore Lost Data due to Disk Conversion

# 2. Create New Partitions on Converted Disk

Your next move is to create new partitions on the hard disk. You have two ways: Disk Management or free partition management software. Here we'd like to guide you go through a manual way.

• Step 3: Set partition size, drive letter and file system (NTFS), etc.
• Step 4: Click "Finish" to complete the process.

Repeat the process if you wish to create multiple partitions on the disk. Then you can save the restored files and data back to the hard drive, reusing the files again.
