[QUOTE="pigoo3, post: 1563838, member: 56379"] Hey guys...I need some help. I have a 2011 27" iMac that I'm having some trouble with. The computer up until today was ok. I wanted to upgrade the internal HD to 1 terabyte. After installing the drive...the computer doesn't seem to want to "see" the internal drive (won't boot from it). I've tried: - PRAM/NVRAM reset - SMC reset - Booting using command +r - Booting from an external drive with an OS on it. - Launching Disk Utility I've tried multiple drives (including the original one)...and I cannot get the computer to boot from any internal drive (it's as if there's no internal drive installed). All drives have tested fine with other computers...so I know that the drives are good. Anybody have any ideas? I'm pretty "frazzled" at the moment. Maybe I'm forgetting something in my frazzled state!:( Thanks, - Nick p.s. Also...as far as I can tell...all plugs & wires are attached inside (didn't forget anything). p.p.s. The computer does not have Applecare. [/QUOTE]
