There is no 'uninstall'.
Either use one of the many cloning tools, or install fresh on the SSD (recommended).
So I would install it on my ssd but what will happen to my hdd that also has all my other stuff and W8.
If you use one of the clone/migration tools, the entirety will be transferred to the SDD.
This assumes that the used space on the existing HDD is
smaller than the new SSD.
For instance, if you get a 128GB SSD, your existing data on the C drive (OS+applications+data) should take up no more than ~100GB.
Or:
Reinstall the OS on the SSD (disconnect the HDD while you do this)
Reinstall all your applications
Leave your personal data (music, etc) on the HDD.
