About data loss and recovery after reinstalling the system.
Reinstalling the system refers to reinstalling the computer's operating system such as Windows/Mac. System reinstallation can solve various system problems, such as computer virus infection, system file damage, system slowdown, crash and unable to start, blue screen, etc. The normal operation of reinstalling the system is to format the original system partition (usually the C drive) and then reinstall Windows or Mac. Before reinstalling the system, you only need to back up the data on the original system disk, such as the files on the computer desktop. However, many users make misoperations when reinstalling the computer system, resulting in serious data loss, such as installing the operating system to a partition with data, repartitioning the hard disk, turning the entire hard disk into one partition, etc.
Can the data lost after reinstalling the computer system be recovered? As long as the data is not overwritten, there is hope for recovery. The specific data that can be recovered depends on the actual data loss. How to recover data lost after reinstalling the system? If you find that data is lost, you should immediately stop all writing operations to prevent secondary damage to the data.

Situation 1: Install the system to a partition with data.
When installing the system, the user will be asked to select a partition to install the system. Normally, the original system partition should be selected, but the user accidentally selected a partition with data. The system installation program formats the partition and releases and installs the operating system to this partition. After the system is installed, only the data in this partition is lost, and the data in other partitions is not affected.
The operating system usually occupies tens of gigabytes of space. A large amount of data writing will cause serious data overwriting, and a lot of data will be damaged or even completely overwritten. It is difficult to completely restore lost data according to the original directory structure. In this case, do not run the system anymore to avoid more write operations during system operation. Connect the hard disk to the computer and use it as a slave disk. Then use data recovery software to perform a complete deep scan of this partition.
Recovery method:
Here, we need to briefly introduce this professional computer data recovery tool - iBekit Computer Data Recovery. This tool can recover various types of computer data, including photos, documents, emails, videos and audios, etc. This powerful tool can recover from Recover data from your computer or hard drive, flash drive, memory card or digital camera. No matter you lost data due to accidental deletion, virus attack, system reinstallation, or computer crash. And it's safe, reliable, clean, and has excellent data protection performance.

Step 2: Check all recovery options and click the "Scan" button to start searching for lost data.
Before starting the scan, you can also select File Type to specify the file type for the deep scan.
Step 3: Preview the file and check the file recovery effect.
By previewing the file, you can determine whether the file is damaged. This step is important, especially when data coverage is severe. If the file fails to be previewed, it means it is damaged, and the file will also be damaged when it is eventually copied. If the missing file has been completely overwritten, the file will not appear in the scan results.
Step 4: Check the files that need to be recovered and click "Recover". Then you can set up a folder in another partition to save the recovered files.
Situation 2: Repartition and format the entire hard disk when repartitioning.
After reinstalling the system, all the original partitions and files are gone. Now there are new partitions on the hard disk and the new partitions have been formatted.
This kind of data loss also severely damages the original data. The repartitioning process erases the original partition and data, and then creates a new partition. In addition, the operating system is also installed, and a large amount of data will be written. Therefore, the data coverage problem is serious, and how much data can be recovered depends on the specific scan results.
Recovery method:
Due to the serious overwriting, it is generally necessary to scan the entire disk to recover data.
Step 1: Find the hard drive where you lost data on the left side of the software.
Step 2: Click the "Scan" button on the pop-up recovery file window to start a complete scan of the hard disk.
Step 3: Preview and recover files.
You will see several "Partitions (Identified)" and "Orphaned Files" in the scan results. Select the files to be recovered and restore them to other disks to complete the recovery process.
Situation 3: Ghost misoperation causes the entire disk to become one large partition.
When using ghost software to install the system, I mistakenly selected "Local > Disk > From Image". After the system installation was completed, the entire hard disk had only one partition (usually the C drive), and this partition was as large as the hard disk capacity. The other partitions were originally All gone.
In this case, there are usually a large number of write operations, but generally the data is written to the beginning of the hard disk. The original first partition (usually the system partition C drive) is severely overwritten with data. The original second partition may also have a small amount of data overwritten, and the remaining partitions are less affected.
Recovery method:
Since write operations will occur at any time when the system is running, you should avoid running the operating system on the hard disk. You can enter PE or connect the hard drive to other computers for recovery.
Step 1: Find the hard drive where you lost data in iBekit Computer Data Recovery and click "Scan".
Step 2: Click the "Scan" button, and the software starts to search for the lost partition.
Step 3: Click "Recover".
After clicking the "Restore" button, the iBekit software will save the partition just searched to the original partition storage.
