Is it possible to transfer the backup please put the method

If you cannot get into Windows it is not possible to transfer the backup, honestly your only option is to reset Windows or to clean install Windows.

Your best option is to reset Windows, then if you do have a system image created you can then use that from inside Windows.

Do you mean system restore or system image recovery
