The GHOST system partition is lost because the wrong option was selected when reinstalling the system, which resulted in the entire hard disk being installed as the C drive. After the installation, there is naturally only one disk left. If you want to recover the data of the lost disk, you need to pay attention not to save new files to the current C disk (because the files saved now may overwrite the data of the original DEF disk). You can remove the hard disk and hang it on another computer as a slave disk or connect a mobile hard disk to restore the data to the mobile hard disk. See below for specific recovery methods.
Tool/Software: Meteor Data Recovery Software
Step 1: After Baidu search and download the program to run, directly double-click the partition to be restored, then decompress it and right-click the software icon to select the "Run as administrator" software.

Step 3: It usually takes a few minutes to half an hour to wait for the software to scan, just wait a little patiently.
Step 4: The program will quickly put the found data into the "Recovered Partition" directory.
Step 5: Check all the data to be recovered, right-click and select "Copy Checked Files", the software will copy the checked files.
Step 6: The last step is done just wait for the software to copy the files.
Note 1: If you want to recover the lost GHOST system partition, you need to pay attention. Before data recovery, do not save new files to the C drive.
Note 2: The data recovered from the lost GHOST system partition needs to be temporarily saved to another disk.
