Well as you've found, you can only recover to a drive at least as big as the original. So your only option is a clean install using the Windows 7 disc, which you can order here.
I've got a link below to a good Windows install guide you may consult if it would be helpful.
I just installed a 250Gb Samsung 840EVO into a brand new Inspiron 3847 last week. The Samsung came with data migration software that worked flawlessly. Unfortunately, it is proprietary and will not work on other brands of SSD. But the point is it can be done, and quite simply, with the right tool. Have you tried a free cloning software option like EaseUS Todo?
