Hello
I installed Yosemite today and now bootcamp doesn't work.
At first I restarted, alt, nothing but mac. I got around this and now windows option does show but i get a black screen with "Missing Operating System"
Please help !
MacBook Pro (Retina, 15-inch, Late 2013)
How did you get around it to get it to show, I have the same issue.😢
Yosemite upgrade has more than likely changed the partitions (especially Recovery) and this will cause problems.
I suggest starting a separate thread and posting the the output (using OS X Terminal) of
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
Enter you password when prompted.
Hi Loner T
thank you for your response
However please help me understand your reply.
Do you mean
1) open osx terminal and
2) type "diskutil list" (minus quotes) and then copy+paste what comes up?
3) repeat step 2 for all of the above?
Yes, but please remove any personal information that you do not want on a public forum before you paste it.

Can you let me know if this was done correctly?
Yes, this was done correctly.
Instead of repeating the steps that you need, can you look at "Missing Operating system_ " After installing Yosemite and start the Testdisk discovery process.
You are missing about 30+ GB which is the gap between GPT#3 and GPT#4 in your GPT output.
Hi Loner T
Following is my thread, please help.
Loner T,
I have a similar problem. I am coming across MANY posts with you as the one solving everyones problem. I am new to this site. For your help do I start a new thread or do I place my question here? Thanks.
