Bootable as external but not when internal

[damnitjim]

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? 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!

Hi,

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?

Thanks!

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!!
