I current own a HP Envy DV7 (dv7-7243cl). I just bought the caddy extension (ran me $38 - cheapest anywhere) and a SSD card. The problem I think I'm going to run into is when I boot the new SSD I will have to install a new new version of Windows 8. How does my computer know what my drivers are. More importantly, can I just put in a recovery disk in the SSD card? Maybe avoid paying for Win8 all together as well. Yeah just need a heads up. Thank you.
