Paragon may be like the free edition of Macrium Reflect.
Macrium WILL NOT restore unless you use a boot disc made with the application. The Macrium staff technical writers were clever enough to not mention this in the documentation. You get to discover it on your own when you try to restore. Crafty, don't you think? Only the paid for version will restore from Windows.
Even if you could restore in Windows, you are probably better off assuming Windows will not be working when you have to restore--so use the boot disc even if you don't have to.
