Apple Intelligence is now available on iPhone, iPad, and Mac!
Hi - I just upgraded to Yosemite and Windows doesn't even show up in my Bootcamp anymore.
What can I do to make this work? Most of my important data is on my Windows partition so this is scary!
Thanks!

Can you post a new discussion and include the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

Hi Loner, thank you for responding. Here you go.
The original HD was 180GB for the Microsoft partition and 80GB for the Mac partition. I am not sure why there is a /dev/disk1 here either :/

Thank you for your help!
Disk1 is not very interesting. You can safely ignore it.
Can you look at Boot Camp Partition Won't Launch After HD Resize in OS X 10.9.5 (and the embedded link in that thread) and start with Testdisk scan?
Your problem is similar and should be correctable.
Thank you - OK I am running test disk right now and following your imgur link steps
Hi Loner,
I ran test disk but not sure what to do next (I have no idea what the output means). Do you mind pointing me to the next steps?

The harddisk (251 GB / 233 GiB) seems too small! (< 430 GB / 401 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...

Hi Loner,
Thank you again for helping out.
OK I went to the next screen, then did a deeper search on the MS Data. It took all night. I am attaching the results after it ran (scroll down), though I'm not sure what to do now.

Are you able to see additional entries, if you scroll past the last entry on this page?
Hi - the test disk exited since an update was installed after this.
Is there some way I can get you that data without re-running the whole thing?
Thank you
Can you run a Quick Search and post its output?
Hi Loner,
Thanks again, here is the output from re-running the quick search:

Hey Loner,
Really appreciate your help on this.
Here you go - I scrolled down since System Volume Information seemed to be related to this topic.

Leave your Testdisk display and start a new Terminal Window. You need to use the following steps.
If you see any error messages during the following steps, please stop and post back here with the error message. The following steps have values from your Testdisk output (and you can verify) in Steps 7 and 8.
Rebuild GPT4 using start/end offsets
This will delete and re-write the GPT partition info for /dev/disk0s4.
Rebuild MBR to match the new GPT information thus resetting the Hybrid MBR. Use defaults for other questions (like partition codes). The only values that need modifications are the Boot flags and step 10. Accept all other defaults that Gdisk offers.
Here is sample Q&A for this section. Please notice the Press Enter/Return.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #2 (MBR partition #2)
Enter an MBR hex code (default AF): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #3 (MBR partition #3)
Enter an MBR hex code (default AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y
Test 1 - Does Bootcamp Volume show up in Finder?
Test 2 - Can you see files in Bootcamp Volume?
Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?
Test 4 - If Test 3 is successful, select Bootcamp and Click Restart.
I'm not sure how to thank you enough for this. I cannot believe Apple has let this bug run wild for so long - the damage would have been catastrophic to me and you are the only person on the Internet answering any questions about this.
If you're in the US and willing to accept some reward for the help you gave me, please let me know - my GMX e-mail alias is tdrx
Thanks again!
Tony
