so today when i got home i turned on my computer, and i noticed that one of the hard drives was making the infamous "clicking" sounds, so i opened up my case and took it out (its one of the old IDE harddrives and i can transfer the data later, no biggie), and then rebooted. now windows wont boot with an error from something saying that i need to connect the boot device and restart, but the problem is that i have my primary harddrive still plugged in. help?
