Tutorial - How to triple boot OSX, Linux and Windows 8.1 with a shared Data Partition without any third party Win / OSX softwares

This is not a question, but rather a personal guide that has proved to be running successfully.
I would like to thank numerous sources, including Christopher Murphy's suggestions at:
Re: Repairing Boot Camp after creating new partition
Before proceeding, there are certain concepts needs to know:
Why Boot Camp does NOT allow further partitioning of drives after Windows has installed?
Answer: Because the way Apple configures the Mac to be recognized as non UEFI capable system on Windows.
Quote from Christopher Murphy based on the above line:
However, Windows on Macs right now use CSM-BIOS mode in Mac firmware that presents BIOS to Windows rather than EFI. Windows thinks it's on a BIOS computer, and therefore mandates the use of MBR for boot disks, rather than GPT. So that's why we have this hybrid MBR+GPT approach on Mac with Windows on it. You inherit the limitations of MBR, which is four primary partitions.
So what does it means?
It means that OSX + EFI + Recovery HD + Boot Camp partition = 4 primary partitions and thus any attempt to modify the disk will render booting issues of either system.
For more info on GPT (GUID Partition Table disks VS Master Boot Record or MBR in short, you may visit: http://msdn.microsoft.com/en-us/library/windows/hardware/dn640535%28v=vs.85%29.a spx)
So, how to overcome it?
The general guideline is to install ALL GPT ready OS first then create a Data partition, before installing Windows (Which is again, NOT supported GPT due to EFI configuration by Apple where end-users are not able to modify it).
Interestingly, since Mac Pro 2013 Late supports only Windows 8 and above, thus it is not known if this CSM-BIOS applies to it or not.
Do take note that GPT disks in Windows can only be booted when the system meets the 2 requirements:
http://msdn.microsoft.com/en-us/library/windows/hardware/dn640535%28v=vs.85%29.a spx#gpt_faq_win7_boot
1) Windows x64 version (Which is a must for newer Macs. If you cannot go to Boot Camp 5, then you need Windows 7 x86 or 32bit version)
2) UEFI system. However, Windows sees all Macs (With the possibility of Mac Pro 2013 Late is an exception. To be determined) as BIOS, or rather NON-UEFI system.
In short, booting on GPT disks is not possible for Mac in Windows.
Summary,
It is tested that a combination of the following will not work:
- OSX + Windows + Linux
- Windows + OSX + Linux
- Windows + Linux + OSX
Usually it can create the system un-bootable or OSX refused to install due to the system does not recognize such partitions and / or Disk Utility refused to format a free space. An example screen-shot is provided below:
The error message is shown as
Title: "Failed to erase volume" Message: "Failed to wipe volume, as an error occurred: MediaKit has reported that the device does not have enough free space to execute the requested operations."
The second thing is about the preparations we need.
1) 1X Windows 7 or 8 DVD or USB thumbdrive
1A) If you uses a DVD to install, you will need another thumbdrive to load the BootCamp drivers for Windows as well as may requires an external DVD drive for newer Macs
2) 1X Linux DVD of your choice. Personally I choose Fedora 20.
So ready? Let's go.
1. Using Disk Utility, shrink the OSX's partition size to what is needed. For me, I give OSX 150GB. Do NOT create any new partition.
Disk Utility should see something like below whereby only OSX partition is left with desired disk space. The remaining space are to be unused disk space for the moment.
Note: Click on the top most item that should start with the size of your HDD / SSD. Then clicked on "Partition" and specify the desired OSX size. Hit "Apply" after that.
2: Download Boot Camp drivers only via Boot Camp Assistant. The USB thumbdrive shall be used later after Linux's installation.
Boot Camp Assistant should see this:
I have only selected "Download latest Windows Support Files from Apple"
3. Insert Linux DVD, reboot Mac into EFI mode (The left most first "EFI mode").
Note 1: Before rebooting, please plugged in an Ethernet adapter because Wi-Fi drivers is not installed.
Note 2: For Thunderbolt adapters, it must be plugged in before reboot as hot-swapping is not supported under Linux. More on the tips at the end of this article.
Note 3: Press and hold "Option" after the screen turns black. Release Option key after you see the image as below:

For the unfortunate part that did not make it on time to edit the images:
9. Install the Windows Support software from your CD/USB drive to gain full functionality of your computer. Reboot and go to Windows again.
Note 1: You may choose to eject disc at this point of time. For Apple SuperDrive users, you will need to wait until the drivers (i.e. Boot Camp support files) is installed and rebooted before ejecting is reasonably possible (As I failed to figured out how to right click without the drivers)
Note 2: Unlike Windows 7 on KBase article TS4599 Keyboard/trackpad inoperative, black screen, or alert messages when installing Windows 7, USB stick can be plugged in after the Windows installation is done. This is because Windows 7 (And probably Windows 7 with SP1 DVD) does not have a built in USB 3 drivers when it was released back in 2009 where USB3 has not arrived then.
Note 3: Due to TPM, Bitlocker is not supported without the use of thumbdrives.
10. Using Disk Management to determine the given drive letter for the DATA partition (DO NOT DELETE and RECREATE partition or else you can goodbye to booting Linux and OSX). Disk Management will not allow you to format it as exFAT / FAT32 in graphical way.
Note: You may remove or modify some of the disk letters in Disk Management. However, do NOT remove / modfify the drive letter for the partition with 200MB size in HFS. This is because it will disallow booting of Linux and neither could Windows nor OSX can do anything EXCEPT to reinstall Linux only.
11. Open Command Prompt in Administrator Mode (Important!!), and key in the following command:
format F: /FS:exFAT
Give this volume a label after it has successfully formatted before hitting "Enter" again.
Note: Mine Data partition was assigned as F drive. Please make necessary adjustment to "F:" should your Data partition is assigned to other letters.
12. After that, Setup your Data partition structure as you like.
Tip: Minimally create the important folders such as:
- Music
- Documents
- Movie (Videos)
- Downloads
- Pictures
All these folders are commonly used by the 3 OSes. I do NOT recommend changing of /home (OSX and / or Linux) and / or user home directory (Windows) either partially or as a whole.
This is because of compatibility issue.
On a side note, iTunes Media Library used in OSX and Windows are NOT able to be use interchangably due to hard-coded path used.
13. Useful troubleshooting in Fedora / Linux:
With references to these:
http://chaidarun.com/fedora-mbp
http://anderson.the-silvas.com/2014/02/14/fedora-20-on-a-macbook-pro-13-late-201 3-retina-display/
http://unencumberedbyfacts.com/2013/08/16/linux-on-a-macbook-pro-101/
I would like to highlight a few important points:
1) Wi-Fi driver:
http://rpmfusion.org/Configuration
Note 1: The sound driver should be installed at Out of Box Experience. However, the Wi-Fi is not.
Note 2: Install both free and non-free repository. By the way, some other software like VLC can only be found after the Free Repository is installed.
Search for "akmod-wl" in Gnome-Package-Installer in order to install Wi-Fi drivers
Note 3: For those who do not have Ethernet adapters and their Mac does NOT have a built-in Ethernet port, it is recommended to get one. This is because Fedora 20 does not have a good support for iPhone USB tethering. Unsure for Andriod / Blackberry / Windows Phone users.
2) Grub Menu:
It will show several options to boot into OSX, even of the capability to boot into x86 or x64 mode. However, neither of them is bootable except Linux and the rescue.
Hence, it is recommended to remove the items by hand in this file:
/boot/efi/EFI/fedora/grub.cfg
Command to be used:
"sudo gedit /boot/efi/EFI/fedora/grub.cfg"
Parts to be removed:
- For any extra kernels, delete the target entry by locating the line "menuentry" under "/etc/grub.d/10_linux" sector to one line above the next "menuentry".
It is recommended to keep one main kernel, and one recovery at the minimal.
- For other OS, delete all the entry (Since neither it can works) under "/etc/grub.d/30_os-prober" sector without removing the lines starts with ###.
Auto Mount exFAT partition:
- After installing extra packages for exFAT support (Since it is not supported by Fedora 20 from a default installation), you may wish to edit "/etc/fstab" in order to mount the exFAT partition during boot time.
Command to be used:
"sudo gedit /etc/fstab"
Add the following line in gedit:
UUID=702D-912D /run/media/Samuel/DATA exfat defaults 1 2
Note 1: For DATA partition, OSX & Boot Camp partition, Fedora defaults mounts under: "/run/medua/<Username with case sensitive>/<Partition Label Name>"
Note 2: UUID is unique ID. You can find out the UUID by:
Step 1: First determine the DATA partition number:
"sudo gdisk /dev/sda"
Step 2: Determine the UUID of this partition number:
"sudo blkid /dev/sda8"
Reference 1: http://manpages.courier-mta.org/htmlman5/fstab.5.html
Reference 2: http://liquidat.wordpress.com/2007/10/15/short-tip-get-uuid-of-hard-disks/
3) Overheating CPU
Solution is to issue the following command in Linux terminal: su -c "echo -n 1 > /sys/devices/system/cpu/intel_pstate/no_turbo"
4) System resumes immediately after suspend
Solution is to issue the following command in Linux terminal: su -c "echo XHC1 > /proc/acpi/wakeup"
5) What does not works well out of box:
- Both GNOME and KDE's fonts are too small to be readable for out of box experience. Additional configuration is a need. (Some of the info can be found on "More Tips" later)
- Thunderbolt hotplugging is NOT supported under Windows and Linux so far. Neither FaceTime HD camera works as well.
- The red light in Headphone jack is always on. I do not have luck in switching off the light without losing the sound.
Note 1: It is determined that the module "snd_hda_intel" is used by both cards (HDMI and normal output)
Note 2: It is also known that blacklisting it can switch off the redlight at the price of muting the system.
Note: Based on this article, http://support.apple.com/kb/TS1574
A Mac (Except Mac Pro) needs servicing when there is a red light while the system fails to detect internal speakers. However, this article does NOT applies to this issue.
5A) More Tips:
Install gnome-tweak-tool for more customization
Search for: "gnome-package" to install:
Install Gnome Package Installer for advanced package repository
Install Gnome Package Updater for advanced updates to be install (Whereby Fedora's App Store alike might not show the relevant updates)
14. Verify if disk is still GPT:
Use Gdisk to determine if the disk is pure GPT:
http://ubuntuforums.org/showthread.php?t=1742682
Command: sudo gdisk -l /dev/sda (The entire hard drive)
You should see the MBR is "Protective" instead of anything else.
15. Congrats, the system is ready for triple boot. (I forgot to eject my Windows DVD when the photo was taken)
Note 1: You cannot set the default startup disk in Linux due to the lack of Boot Camp Control Panel in Linux.
Neither is changing startup disk recommended in Windows due to the inability to display correctly.
For me, I click "Cancel" whenever I am on this tab (Feel free to make other Boot Camp adjustments in other tabs).
Only OSX I know that can show the startup disk options correctly.
Note 2: For some reason, OSX likes to auto mount the EFI partition everytime it boots up. It is not known to have any issue for ejecting other disks or mounting disks via Disk Utility.
Note 3: It is not determined if any Firmware or System upgrades will cause issues. It is only known that all 3 OS's regular updates should not be an issue.
System Updates excludes Mac OSX 10.9.3 updates to OSX 10.9.4 type as I had done it on a OSX 10.9.4 Mac or Windows 8.1 to Windows 8.1 Update 1 since my Windows DVD comes with Update 1.
System Upgrades refers to OSX Mavericks to Yosemite, Fedora 20 to Fedora 21, Windows 8.1 Update 1 to Windows 8.2 / Windows 9 for that matter.
Note 4: Reset SMC and / or PRAM will NOT affect your ability to boot any of the OS (OSX, Recovery HD, Fedora & Windows 8)
Yup, that is it!

How do you create multiple execution windows for a custom opterator interface

I am starting to create a custom operator interface for TestStand 3.5 using Labview 8.0. This is my first exposure to custom operator interfaces (and ActiveX). The example operator interfaces have only one execution window that changes based on the executions combo box. My sequence is going to be run with the parallel sequence model (2 test sockets). So I want my custom operator interface to have 2 execution windows, one for each test socket. How can I do this? I created a second execution window but it just mirrors the first execution window.

Hi, All:
With the similar approach, I create a multiple window user interface with CVI. Although it can run, the Execution view doesn't display
anything while execution. In my user interface, there is an applicaiton manager resident in Parent form, and every child forms has
itsown Exection view and Manager.
Referred to the C# sample, in the function rivate void DisplayExecution(Execution execution)
   if (executionForm == null) // execution is not in a form, make a new form
    executionForm = new ExecutionForm(this, this.axApplicationMgr, execution);
    this.mChildFormsKeyedByViewMgr.Add(executionForm.GetViewMgr().GetOcx(), executionForm);
    SetNewChildFormLocation(executionForm);
I guess the execution form "hook" the exectuion view manager via Add(), so the exectuion view can be updated properly.
And according to reference manual of teststand, it mentions that "The application sets the ExecutionViewMgr.UserData property to
attach a handle, reference, or pointer that represents the window." But when I try to utilize this method, I got 2 problems:
1. How to get a window handle of a CVI panel? As execution view are resident in child panels, so I may need the window handle of
individual child panels.
2. Even the window hanlde is gotten, how can I convert it to a VARIANT Type? According to the function panle of
TSUI_ExecutionViewMgrSetUserData (, NULL, ), the last parameter is a "VARIANT".
Any comments or instructions for my assumption?
Thank you for your help.

Error in Interactive Execution Window kills CVI

Consider the following code:
#include <ansi_c.h>
double y;
y = cosh ( 1000.0 );
This (correctly) yields an ERANGE error. If this code is run in the interactive execution window a popup shows up reporting the non-fatal run time error. So far everything is fine...
However, if you now choose to select 'Continue' the complete CVI window disappears from screen - the only chance to continue is to use the task bar icon and select 'Close Window'. This closes CVI. Quite annoying.
As a side note: If the source code window contained changed unsaved code, the changes are saved without asking. Usually, if I want to close CVI I am asked if I want to save the changes - obviously, the task bar icon does not ask...
Solved!
Go to Solution.

Hello Wolfgang,
it seems to me that what Nelu is doing is:
1. Hover on the icon and wait for the preview to appear
2. Right-click on the preview image to show the context menu with "Show window" option
In the meanwhile, I have discovered another way to display the CVI ADE; if you right click directly on the CVI icon in the taskbar you should see the list of recent files opened: selecting one of them not included in the current project displays the ADE with that file opened.
Doing this, a simple ctrl+W closes the window and you are back with your workbench as you have leaved it. Not exactly user friendly, I know but until it is fixed...

How does Status column in Execution Window get set?

Thanks to Jonathan for the reply to my last post.
I have a couple of inter-related questions on step-types. I understand the difference between a Pass/Fail step type and a Numeric Limit step type is that the code module being executed in one case returns a Boolean whereas the code in the other case returns a numeric.
I looked at the "Edit LabVIEW VI Call" dialog for a LabVIEW Pass/Fail step type and I noticed that the Boolean passed by the connector pane went to "Step.Result.PassFail" in TestStand.
Q1. What exactly is "Step.Result.PassFail" called? Is it a "Parameter", a "Variable", or simply the property of the "Step" object? In other words, how would I refer to it in a discussion?
Q2. If it IS a parameter, then when I use the expression browser in the "Edit LabVIEW VI Call", why do I see ANOTHER object (at the same level as "Step") called "Parameters"? I do realize that this "Parameters" object does not contain anything until run-time.
From the viewpoint of a sequence itself, eventually each of these steps (Numeric Limit OR Pass/Fail) lead to a Passed or Failed (or Skipped) result as we see in the Execution Window.
Q3. I assumed that that result in the Execution window is tied to "Step.Result.PassFail". Is that true?
With that in mind I studied the "Status Expression" for a Numeric Limit Test and this is what I found:
CheckLimits(Step.DataSource == "Step.Result.Numeric" ? Step.Result.Numeric : (Step.Result.Numeric = Evaluate(Step.DataSource)), step.limits.high, step.limits.low, step.comp)
Q4. There is no mention of Step.Result.PassFail in the expression above. Why not? In other words, how does the comparison with limits get translated to the Status column in the Execution Window?
Thank you.

Hi 2and4,
Answer to Q1: Its a property of the Step or Result, depends where you are referencing from. If you are unsure then quote the lookup string eg "Step.Result.PassFail".
Answer to Q2: You are probably referring to the Parameters which belongs to the active sequence you have displayed in the sequence editor. Its empty because you have no Parameters defined in the sequence. Try this, in your active sequence, select the Parameters tab. Insert a Parameter, it doesn't matter what it is. Now view the Sequence Context by the Expression Browser. You should now is a + sign next to Parameter. Expand this and you will see you Parameter you inserted.
Answer to Q3: Yes, the actual result or status is in Step.Result.Status which is a String. This can be "Passed", "Failed", "Error", "Done"
Answer to Q4: If you look at the Status Expression for the PassFail step, you will see it has a different expression. The PassFail doesn't do any limit checking. If Step.Result.PassFail is True then the step passes and if False it fails. It's that simple.
I hope this helps.

Interactive execution window

Hi all,
I use CVI 8.5 but only now I started using the Interactive Execution window. I have some global variables in my main.c but they are not recognized in the interactive window ("Undeclared identifier panelHandle" for example).
Can anybody give me an example or a link of how to use this Interactive Execution window?
Thanks!
Kristel

Well, I didn't noticed it!
I made some test and IEW can effectively catch variables declared as global in a source file, but not if declared in a include file common to all source files in the project. Since all my global declarations are in such files I cannot get them in the IEW. I conformed with it and probably this is the reason I dodn't noticed that small note in the help.

Operator interface execution window is not getting activated-cant terminate,abort

Hi all,
I have sequence running in the operator interface which pops up a panel.It remains visible for some time and the value in a control of the panel is getting updated periodically .It is done using threads.After the panel pops up, until it goes off i am not able to operate with the controls in the operator interface execution window(terminate,abort,break).I changed the floating style of the panel as 'active when clicked on'.
Regards,
Radha R

Radhu,
Is this panel part of the Operator Interface or a dll function call from within your sequence. It sounds like its modal to the operator interface.

How can I tile up the execution window in the Labview Teststand user interface

I am using the Labview User interface provided with the TestStand development environment.
Running the BatchUUT.seq Example using the TestStand Sequence Editor, you will see that the Execution Window will be divided in 4 windows showing the execution status of the 4 UUTs.
Running the same Sequence using the provided Labview User Interfaces (Simple or Full-Featured) will just show one window with the execution status.
Is there a way to tile up the window to display the execution status in the Labview User Interface?

Try something like this:
You wouldn't use random numbers of course, but rely on already opened clones. So you would extend the "Manage Clones" to manage the data for the window position, but set it for each clone in the way the screenshot shows.
hope this helps,

No Execution Window in DI Designer

I don't get an Execution Window when I run a job from the designer. No trace log, statistics log, or error log buttons anywhere. It starts normally (set the configuration, global variables etc and press OK), but then it just goes back to looking like the designer.
I can see the job running from Management Console, just not in the designer.
I used to get it but it disappeared. I uninstalled and reinstalled DI, but still same result.
Any suggestions?

Split execution window in Operator Interface

Hi,
I'm using the NI Parallel Model to test 3 UUTs and I want to use the LV Operator Interface. How can I configure or modify the LV OI in order to see my 3 sockets in paralel while my sequence run?
Thanks,
Angel

Unfortunately I can not. I developed it in my last contract job, and while I did keep a copy for myself, it was written in LV 8.20. I currently don't have a copy of LV8.2 so I can't even view it (my current contract uses LV 7.0). Also, I don't feel comfortable distributing the OI without modification because it does have company info from that contract job that I would want to remove first.
However, I can answer as many questions that I have answers to. In fact, I have posted on this forum asking/answering questions about creating that OI that may also answer your questions.
I would suggest using the LV simple OI as a starting point if you haven't already. Then create a copy of the controls are passed into the subvi "Simple OI - Configure ExecutionView Manager.vi". Create anoter copy of the subvi and pass all controls to that subvi the same as the existing one. The should get you started with a second execution viewer.
One other think I found with the example OI's is that the controls that are already there don't seem be resizable for some reason. I think I ended up replacing them (all the controls are in the teststand pallette of labview).
Hope this helps in getting you started.

Dualboot windows 8.1 with windows 7(recovery product disk)

Hi,
I am currently running windows 8.1 with pre-installed windows 8.I want to dualboot windows 8.1(current windows system) with windows 7 home premium.I have made a hard drive partion and now i have "2" hard disks 500 gb both of "2".I have
a product recovery disk for the windows 7 home premium and i want to use it to do the dualboot with the windows 7.At the back of this disk it says that i must insert the disk to the pc,shut it down and when i open it again press f12 and then instructions will
appear.Unfortunatelly when i press f12 i see a message select which item to boot and has 2 options realtec driven ipvn4 and ipvn6.I selected the ipvn4 and nothing happened.So i want help on how to use it and make this dualboot come true.

You need to contact the manufacturer of your system. Most Windows 8.1 system have protected boot mode and Windows 7 cannot be installed in the protected boot mode. You will have to find out from the manufacturer's technical support
what UEFI/BIOS settings you need to dual boot with Windows 7.

Windows 8.1 with Hyper-V external switch - 802.1x not working in host nor guest

Hi,
I have Windows 8.1 with installed Hyper-V and virtual machines connected via Hyper-V Switch - External. 802.1x wired authentication is not working in host nor in guest machine (computer is not responding to switch requests). If I will change switch mode
to Internal/Private it will start working.
Do you have any idea how to get it working also in external mode?

Hi,
What is the physical network configuration in your environment? Are you using wireless or wired connection?
We tested this issue as you described here, and the external switch is working fine.
Have you tried to delete the created switches and recreate one, test this issue again?
