Bootcamp partition appears as system reserved

A year ago I made an upgrade to my Macbook Pro 15' Mid 2010, bought an SSD with 256gb and replaced my optical bay with my primary HDD 320gb.


In my primary drive (SSD), I installed OS X and with BootCamp I splitter the SSD in half and installed Windows 7 and just wiped my HDD for data. Then last week, I made another upgrade to my second HDD and replaced with a SSHD of 1tb, so I could just keep my primary drive with just OS X and second HDD with Windows (that I barely use, I just need it for work with architectural 3D, like Autodesk Revit).


First, I put my new and clean SSHD in primary bay and made a clean install with OS X Snow Leopard. Then I used Bootcamp to create Windows partition (with 250gb) and installed. Until here everything is fine. Then I swiped back my SSHD to the optical bay and put back my SSD in the primary drive. Everything works fine, when I boot my Mac and press Opt button it shows all the OS. Then back at my OS X in my SSD, I wiped the OS X partition in my SSHD but kept my Windows partition.


The thing is: everything works fine, I can boot to my OS X partition and to my Windows partition when I press the Opt button, but when I boot to my OS X, I cannot see my Windows partition. I used Disk Utility to see what happened and it shows my Windows partition but named as System Reserved. I still can access to my Windows, everything is ok when I boot normally. Is there a way to work around, to get access to my Windows partition HD in when booted into OS X? When I'm at Windows I can see all my hard drives, even my SSD with OS X, but not the other way around...

Please note that my disk1 is now disk0 since I connected my SSD externally like you said (didn't know that I could boot to OS X from an external hard drive).

By mistake, trying to create Windows MBR as System Reserved Partition, I created the partition 4 that I don't know it's useful or not. But I guess it can be erased. Now what we should do then? And actually I don't mind to put it back again like it was, even with no access to Win OS partition from OS X. I just need my Windows to work when I need to boot the machine so I can use the only programs that I can't use on my OS X (Revit and 3D Studio Max).

It also made changes in GPT:

If you are running El Capitan,


1. Boot into Local Recovery (Command+R) during power up.

2. Run Utilities -> Terminal.

3. Type csrutil disable and press return/enter.

4. Boot normally.

5. Type csrutil status in OSX Terminal and verify that is it disabled. If still enabled, repeat.


Once you have SIP disabled properly, install GPT Fdisk - http://sourceforge.net/projects/gptfdisk/ . The following steps are non-standard and should not be used under any circumstances by anyone else.


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. Please notice the'+' sign in step 8 (this is called offset notation). The text in parentheses is for informational purpose to describe the action being taken. Gdisk has one-character commands except when entering numbers.


Rebuild GPT using start/end offsets


  1. Sudo gdisk /dev/rdisk0
  2. P (print the full list of parts)
  3. D (delete)
  4. 2 (part 2 - because we need to split it).
  5. D (delete)
  6. 3 (part 3 - because we need to relocate it).
  7. N (new part)
  8. 2 (part 2)
  9. 411648 ( - Start offset in sectors or the start point for part)
  10. +204800 ( - Size offset, as opposed to End offset)
  11. 0700
  12. N (new part)
  13. 3 (part 3)
  14. 616448 ( - Start offset in sectors or the start point for part)
  15. +488337408 ( - Size offset, as opposed to End offset)
  16. 0700 (Windows part type)
  17. N (new part)
  18. 4 (part 4)
  19. 488953856 ( - Start offset in sectors or the start point for part)
  20. +1464047024( - Size offset, as opposed to End offset)
  21. AF00
  22. P (print list of all parts just to see what changes will be made)
  23. W (Write the new GPT)
  24. Y (Yes! really write the new GPT)

This will delete and re-write the GPT partition info for disk0 (current).

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.

  1. Sudo gdisk /dev/rdisk0
  2. P (Print list of parts)
  3. R (Recover)
  4. O (print current Hybrid MBR)
  5. H (chooses Hybrid)
  6. Partitions numbers to be hybridized: 2 3 4
  7. Y (Good for GRUB question)
  8. Y (part 2 boot flag)
  9. Y (part 3 boot flag)
  10. N (part 4 boot flag )
  11. O (print current Hybrid MBR)
  12. W (Write the new MBR)
  13. Y (Yes! write the new MBR)
  14. 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 #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.

That was hard to do but made it!


Test 1 - Yes

Test 2 - Yes

Test 3 - No

Test 4 - No


Windows doesn't boot, even when I restart my MBP and press Opt key, Windows partition doesn't show. I'm trying to use Windows DVD to try to repair. Any suggestions what to do next?


Btw, thank you very much for all the help and time wasted. Hope that we can solve this issue.

UPDATE: After used Windows DVD to repair, I went to CMD and run Diskpart to make Partition 2 as Active and Partition 3 as Inactive and done!

Now everything works good! OS X and Windows OS are bootable and I can see my Bootcamp Partition on OS X!

Thank you very much Loner T!

All good! Everything works good now! I still don't see my Windows Partition on Startup Disk tho, but it's ok cuz if I can boot manually and pressing Opt key, I can boot to Windows normally.


Is it possible to just add my Windows Partition to Parallels but still make a native boot when restart my MBP and press Opt key? Just in case if I need to run something from Windows quickly but when I need to work with Autodesk Revit and 3D Studio Max I will boot it natively.
