#75248 — Crashed partition recovery problem

I've got a MacBook Pro 17" (MacBook Pro 8,3) with a Snow Leopard 
partition and a Mavericks partition.  The Mavericks system developed a 
disk problem.  Disk Utility said it couldn't be repaired and to 
re-install the system off back-up (dling the os).  This was off the 
Recovery partition.  Unfortunately, I couldn't do that as I got some 
message saying I had no internet connection.  Don't know why that popped 
up but I decided to try booting from the Snow Leopard system.  That 
worked fine but the Mavericks system became unavailable.  I decided to 
wipe the Mavericks partition (Disk Util erase) and install Snow Leopard 
on it and upgrade to Mavericks using my backup along the way. 
Unfortunately, while I could install 10.6.6 off the dvd (this is a 
special system install for this machine) it would not upgrade to 10.6.8. 
  The upgrade downloads but will hang on the reboot.  I've tried it 
twice with the same result.  I even tried simply logging off the newly 
installed 10.6.6 system.  It just hung.  I'm thinking I'm just going to 
have to bite the bullet and make a Genius bar appointment but I was 
wondering if anyone had any suggestions.

It occurred to me that I might be able to install 10.10.3 by using the 
working Snow Leopard 10.6.8 system to access the app store but I believe 
that's only good for upgrading the system that accessing the app store. 
  Is that right?

You can use 10.6.8 to begin the upgrade on the App Store. (aka: download
it). The trick is to not begin the actual installation and before you
quit it, you rename the downloaded .DMG file (the installation software)
so that it doesn't get deleted when you exit the installer.

When you open the .DMG, you'll find an installer app and from it you
*should* be able to specify which disk you want to install it on (I have
not verified this) at which point you specify the partition you intend
to have Yosemite on.

Alternatively, you boot from the partition to be upgraded, mount the
disk/partition that contains the dmg, then you mount the dmg and you can
install in-situ on the currently running partition.


Note: Yosemite makes some changes to partitioning scheme, but I am not
well versed enough to understand exactly what is changed. I assume that
you can continue to have the SL and Yosemite partitions co-exist.

You certainly can have the two systems co-exist on two different 
partitions. I have a large Yosemite and a small SL partition on each of 
my two machines (mid-2010 iMac and early-2011 MBP).

The item you download from the App Store is not a .dmg. It is an
application (.app extension).

To install to a different drive/partition, no special tricks are needed.
You just need to pick the destination at about the third screen on which
the installer pauses during its initial prompting.

I don't recall if I have tested this with an installer I hadn't moved,
but my understanding is that the automatic deletion of the installer
only happens if it is in the Applications folder of the destination
volume of the install, which is the default case if you change no
options after the download. (I've almost always moved my installers
elsewhere before running them, and renamed them so I know exactly which
minor version they install.)

You don't need to quit and run the installer again to get that option.

Mostly right, but you are running an application, not mounting a disk
image.

I haven't spotted a clear explanation of this issue yet. It appears that
in some cases, installing Yosemite will convert the destination
partition to use Core Storage rather than leaving it as a simple Mac OS
Extended partition. If this happens, Snow Leopard cannot access that
partition (nor select it in the Startup Disk preference pane, but the
option key at startup Boot Manager still lets you pick either
partition).

It occurs to me that the partition that held your 10.9 OS has a problem 
but the partition with the 10.6 does not.  If you install anything on 
the 10.9 partition, it may work or it may not.  Or something got 
particularly trashed on 10.9 and it couldn't recover.

To be safe, I'd first check the SMART data on that disk (you have a 
SMART monitoring tool, right?). If it has errors, I'd buy another disk 
and reload everything on the new disk from backups.  If you don't have 
SMART-compatible disk or there are no errors, proceed with caution.  
Anything you do on this partition will likely, at some point, crap out.  
I think that's where you're stuck now.

Buy a new disk and restore from backups.  Or live without the 10.9 
volume.

Thanks for this.  Hadn't thought of restoring to an external.  I'd 
assumed that the fact that the original 10.6.8 system worked fine meant 
that the errors on the 10.10.3 partition (misstated as Mavericks in my 
original post) were of a software nature.  I was tempted to start over. 
  Re-format the entire disk from the 10.6.6 installation disk, partition 
the drive and restore the still working 10.6.8 system from backup just 
to make sure disk errors were marked.  But I was afraid I might run into 
the 10.6.6 -> 10.6.8 failure again.

 From what David Empson posted, it looks like I should be able to 
install a 10.10.3 system by downloading the upgrade and specifying the 
now erased partition.  I'm still leery of the disk as a whole, however.

Looks like you nailed it.  Took it down to an Apple store Monday and, 
after running some tests, the genius person said the internal stock 
spinner had a mechanical problem.  Figured I'd set up the replacement 
drive externally and ran into a problem but I'll start a new thread for 
that.

Correction.  System on the partition that crapped out was Yosemite. 
Gotta start using numbers.  Less likely to screw up.
