Just unplug the HDD when installing OS on SSD. Select the AHCI mode for SATA in BIOS for SSD and make it the first boot device under boot option menu.
Then you can erase the OS from HDD if you like too, and make it a storage drive, if you have space for two drives in your Lappy.
And it better to use a bootable media(DVD/USB) for installing OS.
