As your Windows partition is likely larger than 100GB, you're going to have issues.
When going from a HDD to an SSD, reinstalling Windows
is the generally recommended procedure.
Why?
1. Fresh start on the new drive. Why bring along all that old crap
2. You can't port over
just the Windows install.
Assuming the activation key is still on the bottom of the laptop, you don't have to buy it again. You can download the relevant Windows ISO, and use your existing key.
Look here for the ISO files

Burn to a DVD, and install.
Yes, redoing all your settings is kind of a pain. But it really is the best way to do it.
The only other option is to reduce the size of your Windows partition to under 100GB. Uninstall applications, move personal files elsewhere, etc. Then you can potentially use one of the many clone/migration tools to do it. But you'll still have a lot of reinstalling/reconfiguring to do.
