مشكلة في تمهيد اقلاع النظام

Try the System Restore, if that is not successful, then try the Windows reset method, the image recovery is not an option for you and if none of that works, you will need to clean install Windows from a bootable USB.

I copied the system image from partition to partition, and I think that the partition is primary and not logical. Is this feasible

If you were able to copy the system image, then try using the image recovery option, if that does not work, then you will need to clean install Windows from a bootable USB.

the image recovery is not an option

Is it an option available to me now after copying the system image from partition H to G

If you can find the image on that drive, then use that image
