I have a Toshiba Qosmio G55-Q804 with Vista-64 Home Premium. I want to put in new Sata drive and do a clean install of Windows 8.1. Keep asking me to insert disc... but it's already in the cd slot. Where am I going wrong? **Not tech saavy, just need a step-by-step helper who has lots of patience. :)
