I installed windows 10 via bootcamp, without any external drives, on my 256GB ssd. I then used disk utitlity to create a shared partition by shrinking the OSX partition. After that, when I boot into windows it shows me the recovery screen. Please, help me with each step. I don't want to mess anything up.
Thanks.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
Let us check partitioning first. Can you post the output of the following OS X 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.
Thanks, you were the person I was hoping to respond.
(Sorry for the late response)

Oh, one more thing. I don't know from when but the bootcamp partition stopped showing up on finder. Is it sth I can fix?
Your problems stem from the extra partition. Do you want to keep it? What year/model is your Mac?
Yes I would like to keep the partition "Shared", i'm planning to use it as a storage both OSX and Windows can access.
Its Macbook Pro with Retina display, 13inch, early 2015, upgraded only SSD to 256GB.
1. The restriction is due to the use of an MBR (as shown by the Fdisk output).
2. Your 2015 Mac does support EFI installation, which removes this restriction. You will need to remove the current Windows installation, after you make a good backup of OS X and Windows.
3. If you stay with the current MBR, to make this work, Windows will lose visibility to the OS X partition, but can be made to see the shared partition.
Please decide what you want to do, and I can provide steps.
Sorry again for the late response.
I wouldn't like to remove the windows install, it has important files in it. It's okay to have windows not see the OS X partition, as long as both windows and OSX can see the shared partition. Since that was what I was intending.
A. Disable SIP.
1. Boot into Local Recovery (Command+R).
2. Start Utilities -> Terminal.
3. Type csrutil disable in Terminal and press Enter/Return.
4. Type csrutil status.
5. Boot normally, and type csrutil status to confirm that all individual entries are still disabled.
B. Rebuild non-standard MBR.
The following steps are non-standard because there is a third user-visible partition. Typically, there are two such partitions in a normal configuration on a single-disk Mac with OS X and Bootcamp. This is fragile and lack of proper backups can lead to potential data loss. Download GPT Fdisk from GPT Fdisk and install it on the OS X side. The following steps are executed when booted in OS X.
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. Please see thesample Q&A as an example. These steps can be repeated if you make a mistake before you get to Step 12, otherwise start from Step 1 for these steps. Step 6 has numbers which are typed with a space between the numbers. Please see the sample Q&A before you execute these steps.
Here is sample Q&A for this section. Please notice the Press Enter/Return. Accept defaults offered by Gdisk.
Place EFI GPT (0xEE) partition first in MBR (good for GRUB)? (Y/N): Y
Creating entry for GPT partition #3 (MBR partition #2)
Enter an MBR hex code (default AF or AB): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #4 (MBR partition #3)
Enter an MBR hex code (default AB or 0B or 0C): Press Enter/Return
Set the bootable flag? (Y/N): N
Creating entry for GPT partition #5 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y
This happened, and prevented me from doing the next steps.

I'm really unfamiliar with commandlines. Can you help?
Can you find out the exact version of OS X? Please do not post the serial number of your Mac.
OS X 10.11.3
What is the version of the GPT Fdisk package? It should be 1.0.1.
I have reinstalled gptfdisk 1.0.1, i had the wrong version before.
I finished the process, but it's still same: when I boot into windows, it's showing me automatic repair. I'm sure I disabled SIP, and followed all the steps with gdisk.
Is there something I missed?
If the following tests all work
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.
but Windows does not boot, you will need Windows Startup Repair using the Windows Installer.
Please see http://windows.microsoft.com/en-us/windows/startup-repair-faq#1TC=windows-7 . You will need the W10 installer.
Test 1, 2, 3, 4 all does not work. It's not showing up in finder, i cant see the files, i cant slect in startup disk.
What do you think is wrong? Should I re-do the steps in step B?
Okay, I found my problem. I had installed NTFS-3G, an application that allows writing on NTFS partitions from OS X. After I uninstalled this, and rebooted, its working. I'll try making my new startup repair disk.
