Q: Cannot boot without without first booting to ubuntu live disk

Hi All,

 

I have a macbook pro late 2012 which had yosemite beta on it when I tried to install windows technical preview via bootcamp. Pretty bad idea, I suppose.

 

However, this first went fine until some update on windows forced a reboot. After that it would not boot up again and question mark folder rised.

I figured that I am able to make it boot again when using an ubuntu live disk and selecting "Check Disk". After that I reboot and Macintosh HD is able to boot.

 

However, since I backed up all valuable data, I first removed Bootcamp on Yosemite and as that did not help, I opted for Internet Recover after various tries of reinstalling Windows and removing via bootcamp.

 

So currently my macbook is on Mountain Lion with no (visible, at leas to me) Bootcamp partition

 

When I don't use Ubuntu Live disk and try a Mac OS Thumb drive instead, the complete hard drive is missing in disk utility.

 

What I also found out is that while being bootet to Mac OS i can safely restart multiple times. Only when shutting down completely reboot will not work and I'll get the question mark folder

 

So here's the output of various command line scripts when booting to Mac OS Mountain Lion

diskutil list

If anyone could help me with this, I'd really be grateful.

    There are multiple cases of what I see / saw

    Mac OS Version

    State where I can boot to Mac OS

    (after boot-cycling with the live CD)

    State where I can't boot to Mac OS
    Yosemite Beta (two days ago)Macintosh HDflashing question mark / internet recovery
    Mountain Lion installed erasing the partition only (one day ago)Macintosh HDflashing question mark / internet recovery
    Mountain Lion installed erasing the whole disk (current situation)"Ohne Titel" (=Untitled) | "Wiederherstellung 10.8.5" (Recovery 10.8.5)did not yet try, proably "Wiederherstellung 10.8.5" = Recovery

     

     

    Please note: The hard drive name currently is "Ohne Titel" which was the default that disk utility proposed. I did not change that, so thats my former "Macintosh HD".

    Intersting side aspect:

     

    I installed Yosemite yesterday as an upgrade of Mountain Lion. This has changed since:

    1. When Mountain Lion just freezes after putting the MBP to sleep, Yosemite seems to bluntly restart
    2. When I'm in the situation that I can boot up Yosemite (after Cycling a Ubuntu "Check disc for defects") and then press the ALT key, it shows me only my Hard drive "Ohne Titel". The Recovery partiton is not visible anymore. Could very well be some behavior of Yosemity to make Boot menu more lean.

     

    Also  I did try the following after instally Yosemite: I created the bootable USB drive but didn't repartition my hard disk first. I booted that up and it showed my the following layout

    Partition NameTotal sizeFree sizeType
    Diks 0 Partition 1: EFI200,0 MB181, 0 MBSystem
    Disk 0 Partition 2456,0 GB0,0 MBPrimary
    Disk 0 Partition 3619,0 MB0,0 MBPrimary

     

    When I then repartitioned my disk using Yosemity Bootcamp Assistant and booted up to Windows Installer again it looked like this

    Partition NameTotal sizeFree sizeType
    Diks 0 Partition 1200,0 MB0, 0 MBPrimary
    Disk 0 Partition 2315,9 GB0,0 MBPrimary
    Disk 0 Partition 3619,0 MB0,0 MBPrimary
    Disk 0 Partition 4149,0 GB149,0 GBPrimary

     

    I suppose this is the normal configuration?

     

    Could anybody (Loner T?) confirm

    What could my next steps be?

     

    Many thanks and kind regards

    This is the correct layout. Windows Installer cannot read the size of OS X and Recovery HD partitions, since it has no built-in HFS+ drivers. BC Drivers will install such drivers. Disk0s4 (149Gb) is the designated BC/Windows partition, and it will be FAT, but Windows installer will reformat it to NTFS.

     

    Please see https://help.apple.com/bootcamp/mac/5.0/help/ for details.

    After installing Windows 8.1 Pro on the bootcamp partition I can confirm that there's something to the hybernation of the system.

     

    Remember, the system hangs after sleep / hybernation in Mac OS X. It restarts with an error even in Windows after hybernating.

     

    I'm beginning to think that this is some kind of either dying hard drive or missbehaving power management of the MBP.

     

    As I mentioned I'm having the most current firmware / SMC version. Would it be possible to force-install them again, just to make sure everything is correct? Any other thoughts on my problem?

    You will not be able to force install. On the OS X Side, can you check System Report -> Power and does this happen with the power adapter plugged-in and disconnected, both?
