ExImager

ExImager is a program that allows you to create a backup of your operating system. The backup can be saved to your hard drive, USB drive or other media. ExImager can back up both your operating system and all your data. The backup can be compressed to reduce its size. ExImager also has the ability to create an MBR partition, which is necessary to run the operating system.

Here are the steps to create a backup of your operating system using ExImager:

1. Download and install ExImager.

2. Run ExImager.

3. Select the disk or partition you want to back up.

4. Select the location where you want to save the backup.

5. Select whether you want to back up the entire disk or only selected files.

6. Click the "Backup" button.

ExImager will create a backup of your operating system and save it to the selected location. If you ever have problems with your operating system, you can restore the backup and restore your computer to its original state.
