Q: Another bootcamp snafu after OSX update; please help.

Early 2014 27" iMac, i7, 3T Fusion Drive, 32G RAM, OSX & Win8.1

 

Problem: I updated OSX and after that I was unable to boot into Windows8.1x64 via BootCamp.  I am able to run my Windows installation via Parallels (10) and I can see the Bootcamp dialogue if I request it on startup. If I try to boot into Windows either from OSX or from Bootcamp I get the following message (paraphrased): Your PC needs to be repaired, Error code 0x000000e . Any command attempted / repair attempted whether from thumbdrive or HDD loopsback to the same message.  Only with a hard reboot can I return to OSX. Attempts to recover the entire drive from an Acronis 2014 sector-by-sector image created before the update fail.

 

My level of expertise is low.

 

I decided to post a question after reviewing the following excellent threads here:

Repairing Boot Camp after creating new partition

"No bootable device --- insert boot disk and press any key" after setting up Bootcamp

 

I believe I can follow them, but have not tried the solutions yet because I don't want to screw the machine up and the results of queries I make are a little different than their examples.

 

I include below the results of my queries beneath and thank anyone in advance for their help.

A:

The reason you see two Windows entries, is because of the following entries in the GPT...

 

  391114752  1955307520      4  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7

  2346422272  1948538880      5  GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7


*4: 07 1023 254  63 - 1023 254  63 [ 391114752 - 1955307520] HPFS/QNX/AUX


The current Windows-on-Mac leaves a lot to be desired. It uses a Hybrid MBR (there is a very succinct explanation here http://www.rodsbooks.com/gdisk/hybrid.html ). The entries on the FDisk side show MBR, while the GPT commands show the GPT. If you notice, the start/size for GPT#4 and MBR#4 are identical.

 

To fix BCD issues, in W7 this is what is usually recommended - http://support2.microsoft.com/kb/927392

 

You may also want to look at http://pcsupport.about.com/od/fixtheproblem/ht/rebuild-bcd-store-windows.htm

 

F8 or Fn+F8 should let you bring up W8.1 repair. EasyBCD is PC-centric, but the FAQs are a good source of information.

    Let me look at Acronis and check what viable options can be tested without compromising your requirements. I think I do have Acronis TruImage on one of my minis but I have very seldom used it.

    LT,

     

    i am working my way through reconstruction from clean install with the SDD and HDD respectively split. I have not attempted to use Parallels yet and will need guidance based on my last experience. My sticking point so far is forcing applications to install on the HDD (D drive) rather than SSD (C drive). Obviously one can tell each application to install on D and I have even set the default application path to D:/Program Files, but some applications still go to C. Most notable is Adobe Master Collection CS6 which will not install completely to D, will not work if installed to D anyway, and which locks up when installed to C because it used up the remaining space and cannot access its own scratch file. I am puzzling over that one.  More later, FYI.
