View Full Version : Bootable as external but not when internal

09-12-2008, 03:18 PM
I was able to boot from a newly cloned hard drive when I used it as an external hard drive. I used an external hard drive enclosure for it.

I thought everything was peachy so I opened up the laptop and swapped the hard drive with the new clone. Now when I boot up its telling me it cant find a bootable drive.

Whats going on? :confused: Thanks for any help!

It looks like I needed to do cmd+opt+P+R to reset the NVRAM. It found the new cloned internal drive and booted up. Woohoo!

Glad you figured it out! :)

I have the same problem. I can boot my newly cloned disk while plugged in to the USB (even if I remove my old internal drive), but once I stick it in the internal slot, it won't boot. The screen stayed on Apple for a while and then turns into a "no" symbol.

Anything I can do?

Did you hold down Option and select it from the boot menu?

Yes, I held the OPT key, and it does see the internal drive named "Macintosh HD" (I have renamed the cloned drive as "Macintosh HD") and I know it's internal b/c the icon is an internal drive rather than a USB drive.

Any other ideas for me, please? Thanks!!

And you selected that, but it didn't work?

Yes, correct. It works when I have it connected via USB, but not as internal drive.

I don't know why that would be. Sorry.

I'm running System Profiler on the hard drive while it's in the internal slot. Its Model is External Disk 0. Does that sound like something that has to do with why it's not working?

I don't have any idea why the drive would identify itself as external if it's internal.
