Hi everyone, I got a new mobo and cpu yesterday and after installing all the parts I put my old hdd in, after the pc boots I got an error; no hard disk detected. i know the hdd is fine because i put it back in my old build and it booted fine, i know when installing a new mobo you should format which ive been trying to do but when i reach the window where you choose the language theres no mouse or keyboard working, and i know the mouse and keyboard is fine because i used both in the boot menu. my current specs are p8z68-v asus intel i5 2500k nvidia 560ti asus corsair 850watts 8gb ram 500gb hdd ps; sorry for poor grammar and spelling mistakes but was forced to write this on my phone. Also, i looked in my bios and it clearly names both my hdd and blu ray drive.
