sorry if the formatting is bad

Aug 24, 2015 10:51 AM in response to dgnhlpby Loner T,No worries about formatting. . Looks clean. Please test switching between the two OSes and visibility to the Shared partition after the following steps. You will not be able to see the OSX partition from the Windows side, because it will be combined with Recovery HD.
This is not a standard Hybrid MBR. Standard MBR contains GPT 2,3,4 but we are using GPT3,4,5.
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 the sample 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.
- Sudo gdisk /dev/rdisk0
- P (Print list of parts)
- R (Recover)
- O (print current Hybrid MBR)
- H (chooses Hybrid)
- Partitions numbers to be hybridized: 3 4 5
- Y (Good for GRUB question)
- N (part 2 boot flag)
- N (part 3 boot flag)
- Y (part 4 boot flag make NTFS bootable partition)
- O (print current Hybrid MBR)
- W (Write the new MBR)
- Y (Yes! write the new MBR)
- Reboot
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 #3 (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 #4 (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 #5 (MBR partition #4)
Enter an MBR hex code (default 07): Press Enter/Return
Set the bootable flag? (Y/N): Y

Aug 25, 2015 8:38 AM in response to Loner Tby dgnhlp,I now have 3 options at boot. Mac OSX, Windows, and EFI Boot. Both EFI Boot and OSX boot to osx. and Windows boots to the emergency windows 7 installation i made, not the windows 10 installation im looking for.
Here are some outputs I thought you might ask for:
edit: by the way i apologize for the delayed responses. I'm active duty military and receiving training about 10-12 hours a day during the weekdays so I don't get a whole lot of time to play with this. I really appreciate the help though.

Aug 25, 2015 10:13 AM in response to dgnhlpby Loner T,Thank you for your service to whichever country's Armed Forces you are serving. Post back when you have time. . One suggestion is to switch to OSX if possible, since it has richer tools to go further.

Aug 29, 2015 11:19 AM in response to Loner Tby dgnhlp,Sorry for taking so long to respond. I am booted into OSX and ready for further instructions for recovering the win 10 partition. I have all day today and tomorrow open for working on this.
Thanks again!

Aug 29, 2015 2:41 PM in response to dgnhlpby Loner T,We fixed your OSX booting issue using Widows 10 Gdisk commands. You should be able to switch between OSX and Windows using Boot Camp: Set the default operating system or using the Alt/Option key during power up/down cycle.
Your W10 should also boot normally now. Please test. If you see any issues with W10 or missing W10 drivers, please post back.

Aug 29, 2015 2:50 PM in response to Loner Tby dgnhlp,No I have 3 options at boot. Mac OSX, Windows, and EFI Boot. Both EFI Boot and OSX boot to osx. and Windows boots to the emergency windows 7 installation i made on the partition that i made (which originally messed everything up), not the windows 10 installation i'm looking for.
I still have no access to windows 10.

Aug 29, 2015 2:56 PM in response to dgnhlpby Loner T,From the MBR perspective, the Windows that is currently booting is GPT#5 which is 279GiB. Is the 92GiB partition the Windows 10 partition?
-
Aug 29, 2015 3:04 PM in response to Loner Tby dgnhlp,279 is the windows 10. But windows 7 (92gb) is what boots when I choose windows and also when I chose to restart into windows from within osx

Aug 29, 2015 3:57 PM in response to dgnhlpby Loner T,If you select the Bootcamp Windows, which version of Windows do you get?
-
Aug 29, 2015 3:59 PM in response to Loner Tby dgnhlp,it doesn't tell me which version that one is but if i click to restart into that one it still goes to windows 7.
