A system image can usually be copied as files to another drive, but the copy is useful only if all image components remain together and the recovery environment can find and read them.
A Qiling image is not the same format or folder layout as a Windows Backup and Restore image. Locate the exact image files and any related incremental or differential backups before moving them. If the backup uses a chain, copying only its newest file can make it unrestorable.
Do not confuse copying an image file with restoring it. A copied image is stored backup data; it cannot start Windows directly.
If the old image is incomplete, on an unreliable disk, or tied to a confusing chain, create a new system backup directly on a separate physical drive. This captures the current Windows state, which may differ from the older image. Keep recovery media and the destination drive available for a future restore test.
Choose this route when you want a new backup rather than merely moving an old image file.
Step 1. Connect a separate backup drive and open Qiling Disk Master. Under Backup and Recovery, choose System backup.

Step 2. Check the automatically selected Windows and boot partitions. Keep the required EFI/System Reserved and recovery partitions included where shown.

Step 3. Use the destination browse icon to select a folder on the healthy external drive, click OK, and check the available space before proceeding.

Step 4. Click Proceed and wait for the image task to finish. Browse the image from Qiling and keep the old copy until the new one is verified.

Can I put a system image on the same physical disk? You can, but it will not protect against failure of that disk.
Will copying an image make the other drive bootable? No. A system image must be restored to a suitable destination before Windows can boot from it.
Copy complete image sets, verify them, and keep a separate physical copy. Create a fresh image when the old set is incomplete or hard to validate.
