"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?"
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.
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:
A reliable hard drive recovery tool or software can help you simply restore data from the deleted hard disk partition. Here we'd like to recommend you to try Deep Data Recovery. This software is capable of retrieving data from complex situations, such as unallocated hard drive recovery.
It's fully compatible with Windows 10/8/7/XP and even Vista. All levels of users can apply this software to fix their data lost issues in only 3 steps.
Install this software on your PC and follow to recover lost data after disk MBR to GPT conversion:
Step 1. Run Deep Data Recovery. Select file types and click "Next" to start.
Step 2. Select the partition where stored the lost files and click "Scan". Qiling data recovery software supports parition recovery with FAT(FAT12,FAT16,FAT32), exFAT, NTFS, NTFS5, ext2, ext3, HFS+, and ReFS file system.
Step 3. If you want to quickly find the lost data from the numerous scan results, you can use the filter or search function.
Step 4. You can preview files before recovery. Then, select all desired data and click "Recover" to restore files from existing partitions. Do not save the files to the partition where you lost the data.
Note: Save the recoverable files and data into an external hard drive before making the converted disk available for using again.
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.
To create partitions on unallocated hard drive with Disk Management:
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.
The other solution that you can try is to directly apply reliable partition recovery software to restore the deleted partitions with data due to disk conversion. Qiling Partition Recovery supports to directly scan the unallocated disk and find all the deleted partitions with data without changing the disk partition style (keeping its converted state - MBR/GPT).
As this software is a trial edition, you can go through the process without paying until making sure this software indeed find your partitions and data at step 3. Here are the detailed steps:
Step 1. Run Qiling Partition Recovery on your PC.
Select the disk or device where you lost partition(s), click "Proceed" to continue.
Step 2. Wait for the scanning process to complete.
Let the program scan the selected disk and find the lost partition(s).
Step 3. Preview and restore the lost partition(s).
Double-click on the partition which is marked as "Lost" with "Good" recoverability.
Preview the content of the lost partition. Click "OK" and click "Proceed" to start restoring the lost partition.
Step 4. Click "Recover" to finish the partition recovery process.
Note: If the program warns you that there is a conflict, back up the listed partition with essential data to an external hard drive first. Then execute the final operation to restore your lost partition.
To sum up, both two solutions provided on this page can work to restore lost data and partitions due to disk conversion - MBR to PGT or vice versa.
