Lucas I just got it installed on my y510p as well ive got triple boot going, if you find anything on getting it to boot with the second in let me know. also if you don't have a wifi adapter yet i recommend this one its great works like a chram I just installed the driver reboot and instant internet. http://www.edimax.com/en/support_detail.php?pd_id=347&pl1_id=1&pl2_id=

Any way it works great but I also cant boot with second card in. I remember getting a nvidia pci7 message or something then it freezes is that what happens to you as well?
