Feb 5, 2015 6:31 AM in response to bdaniels72by Loner T,Do you have Control Panel -> System -> Boot Camp? If yes, can you switch to OSX?
You can also try SMC Reset and PRAM reset from Startup key combinations for Intel-based Macs - Apple Support.

Feb 5, 2015 6:43 AM in response to Loner Tby Jamiemacintyre120789,Hi Loner T
I am reaching out to you after reading a previous post about the Yosemite upgrade partition bug and that you have actually led more than 2 people I can see to a solution. I have had an Iphone5s for a while but have ventured into the world of Mac OS, however I couldn’t be completely without Windows for work reasons and some software that I own.
Anyway, I live in the UK and am at work at the moment and so don’t have access to the laptop (2014 15” Intel Core Duo Macbook Pro Retina) but I have exactly the same problem as mentioned before. I was on Maverick and had Mac OS and Windows 7 running on a separate partition through BootCamp without a single problem for ages and yet, and this is most pressing point of it all to me as you obviously know, you use BootCamp which is Apple software bundled with the Mac and then you update with Apple’s OWN OS update, having done nothing wrong yourself other than use Apple software, and yet it messes up the partition.
I now can only boot to Mac OS and see this fabled Disk0s4 where my drive once was, as well as in the boot menu not seeing the windows disk or the recovery disk, only the Mac OS disk.
Your help to fixing this would be very very much appreciated and I would be glad to be of some help to you in the future if i can.
Let’s work together and try and fix this please if you don’t mind. I realize there might be a time difference issue, so if you could email ?
Cheers
Jamie

Feb 5, 2015 6:58 AM in response to Jamiemacintyre120789by Loner T,Please start a new thread. I also suggest looking at Bootcamp disk0s4 gone after Yosemite update as an example. Two tools which are used for diagnosis and repair are Testdisk and GPT Fdisk. You can install these on the OSX side. If you need details let me know. Most of the issues usually stem from resizing/re-partitioning activity on the Windows side. Looking forward to your new discussion post.

Feb 8, 2015 3:14 PM in response to bdaniels72by Loner T,Can you download GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) and install it on the Windows side? If you can, please post the output of
sudo gdisk \\.\physicaldrive0

Feb 8, 2015 3:52 PM in response to Loner Tby bdaniels72,I downloaded it and ran it and entered: sudo gdisk ||.|physicaldrive0 at the command prompt and it just closes.
I read through the readme files so I also tried sudo gdisk \\.\physicaldrive0, sudo gdisk32 \\.\physicaldrive0, gdisk \\.\physicaldrive0, and gdisk32 \\.\physicaldrive0
Each one simply closed the command line window and provided no obvious output.
Perhaps I missed something.

Run it from a CMD Window with Admin rights.
Try gdisk \\.\physicaldrive0
or

Feb 8, 2015 4:25 PM in response to Loner Tby bdaniels72,Ok I tried that and a bunch of other combinations and it always flashed a message that said "Problem opening gdisk ... (it would close before I could read the whole message) then realized that I may need to back up a step.
The walk through doc you linked to says: Command (? for help):
After I double click on the gdisk32 exe file it opens a command line window that says:
GPT fdisk <gdisk> version 0.8.10
Type device filename, or <Enter> to exit:
Is there a command I need to do first before the gdisk ||.|physicaldrive0?

Feb 8, 2015 5:25 PM in response to bdaniels72by Loner T,You do not have a Recovery HD, which is a bit strange, but not the real issue.
You have a 344 GB Macintosh HD, so you should be able to boot.
1. If you power cycle the Mac and hold Alt key when powering up, do you get an option for Macintosh HD?
2. If you SMC reset - Intel-based Macs: Resetting the System Management Controller (SMC) - Apple Support, do you see Macintosh HD using the Alt key?
3. You show about 465GB for the disk and Gdisk agrees. Is this the correct size of your physical disk?
4. You can also check in Control Panel -> Administrative Tools -> Computer Management -> Disk Management.
