Have you tried repairing Macintosh HD with Disk Utilities? If the file
system allows (ie HFS+), I'd run Diskwarrior on it via your external
drive.
Failing that, I think I would try installing the OS having booted up
from the external, onto the HD.
Good luck (is this time to ask whether it's regularly backed up?
Possibly not... but if you have the capacity to take a snapshot of the
current drive somewhere safe, I'd recommend that)
cheers

It's a long story - which I won't bore you this - but the result is
that my
daughter's MacBook won't boot.
When switched on it has a kernel panic.
Holding down Cmd+ R loads MacOS Utilities and running Disk Utility
reveals
it has four 'drives'
HGST SATA Internal Physical Disk
and under that 'Macintosh HD'
Disk images
Apple disk image Media
OS X Base System
Trying Cmd+I on each of these in turn says that none of them is
'bootable'.
I've tried reinstalling the OS via the Internet but it wouldn't
complete
the operation. Internet Recover ran overnight without any joy.
Any thoughts as to my next move? I can start the machine using an
external
disk (one from my old machine from when I upgraded to an SSD).
Any help appreciated.
Thanks!
Rob
