Mar 22, 2015 12:35 PM in response to luck3yby Loner T,This fix usually works if you have a valid NTFS header. Yosemite upgrade does cause some issues.
Can you post the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0

Mar 22, 2015 4:11 PM in response to Loner Tby luck3y,Okay. Yeah know how my problem arose. I was trying to get my Steam and League of Legends to work on my mac. And for some reason I did not have a Case Insensitive System. I would get the error, "Patcher has detected that the local file system is case sensitive" and would not play. I tried to create a case insensitive partition to play my games. Here are my results from your proposal:

Mar 22, 2015 4:14 PM in response to luck3yby Loner T,1. You have a gap between GPT4 and GPT5.
2. Your MBR does not exist. Was Windows installed using EFI Boot?
3. You will need Testdisk and GPT Fdisk to scan for a lost NTFS partition. If you want to keep "Mac 2", it would require a custom Hybrid MBR.

Mar 22, 2015 4:25 PM in response to Loner Tby luck3y,Im not sure what the gap means between gpt4 and gpt 5.
Windows was installed using Bootcamp.
And I would like to keep Mac 2 unless you know how to change my Mac from case sensitive to case insensitive without having to reinstall the os or anything.
Thanks again for helping.

When you installed OS X on Mac 2, the Windows partition was already there. It did two things, created disk0s4 pushing Windows to disk0s5 and then overwrote the MBR. This is an unsupported disk layout on single-disk Macs.
And I would like to keep Mac 2 unless you know how to change my Mac from case sensitive to case insensitive without having to reinstall the os or anything.
What type of information (files, directories, photos, music,...) do you have on the original Mac partition other than the OS?

Mar 22, 2015 5:43 PM in response to Loner Tby luck3y,Oh I see.
And I don't have too much, just some pictures and documents.

Mar 22, 2015 7:48 PM in response to luck3yby Loner T,1. Run the following command. This checks if the NTFS header on your BC/Windows is valid.
sudo dd if=/dev/rdisk0s5 count=1 2>/dev/null | hexdump -C
2. If it is valid, download GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) and I can give you steps to create a custom MBR which will allow Windows to boot. Once it is fully functional, make a backup to an external disk formatted as NTFS. This keeps Windows safe.
3. Copy all files you need from Mac to an external disk. It can be the same disk as in step 2, but you will need a separate FAT partition to copy your files. This partition can also be OS X Case-insensitive. This keeps your OS X files safe.
4. At this point you have a choice to make.
a. The Easy option
1. Boot into Internet Recovery (Command+Opt+R - the spinning globe must show up. Use an ethernet connection).
2. Erase your internal drive. Install a clean copy of OS X using case-insensitive file system.
3. Restore your Mac files from step 3.
4. Install Windows using BCA with a partition slightly larger than the current size.
5. Restore Windows.
6. If necessary, use GPT Fdisk to create a new Hybrid MBR (this is the standard BC MBR, not the custom one built step 2).
b. The Hard option (this requires work in Terminal).
1. Run Diskutil mergePartitions command and merge disk0s2, disk0s3, disk0s4.
2. Reboot and re-install OSX on this merged partition, which will be the new disk0s2.
3. This can cause problems with Windows, which can be fixed, if necessary. The primary culprit is the Recovery HD, which needs to be disk0s3 and there
is no easy method of creating disk0s3 manually.
4. Restore your files from step 3.
Test and verify OSX and Windows.
There are many variations possible to these steps, so please ask questions.
In step 1, if you do not have a valid NTFS header, you will need Testdisk (http://www.cgsecurity.org/wiki/TestDisk_Step_By_Step) and fix Windows first. This procedure also requires GPT Fdisk from step 2.

Mar 22, 2015 8:12 PM in response to Loner Tby luck3y,Thank you so much for the help. I am not sure I want to reinstall my os or anything to fix this. I will look in to what you told me and may end up just wiping windows and reinstalling. Thank you again for your help.

Mar 23, 2015 5:18 AM in response to luck3yby Loner T,The current partition configuration will not allow a new installation of Windows. You had Windows in place before you installed Mac 2, so it is there, but not working. If you wipe Windows now, BCA will refuse to partition and install Windows.

Mar 24, 2015 2:30 PM in response to Loner Tby luck3y,Hm, okay. Is it possible to completely restore everything and get my Mac to a case insensitive file system?

Mar 24, 2015 7:06 PM in response to Loner Tby luck3y,Okay. I will probably do that. I do not have any of the Mac cds that came with the mac will I need any of those?

Mar 24, 2015 7:11 PM in response to luck3yby Loner T,You may be able to use OS X: About OS X Recovery - Apple Support.
If you Mac is on this list, you can also use Internet Recovery Computers that can be upgraded to use OS X Internet Recovery - Apple Support.

Mar 24, 2015 8:42 PM in response to Loner Tby luck3y,Okay I backed everything up to an external device. I m now going to go through the restore process.
