I have Win 8.1 (sic) + GA, on 2 different SSD drives, no problems.
Just be careful during installation to point to the correct drive, you know what I mean.
Use UEFI installation if your BIOS supports it, it works great. You won't see a boot menu after installation (grub, etc.) if that's what you expect. You'll have to manually press F8 or whatever key your BIOS uses to bring its built in boot drive menu, and pick the one you want. If nothing is pressed, it'll boot from the default drive (by BIOS selection).
