Bootcamp partition appears as system reserved

Question

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...

1. What is the version of Windows?

2. Boot Windows and run msinfo32 and check the installation mode.

3. Please post the output of

sudo fdisk /dev/disk0

sudo fdisk /dev/disk1

I am running Windows 7 64x. I saw another threat saying that could solve the problem if I marked my partition as Active in Windows 7 (since I run Disk Management in Windows and in fact my boot partition wasn't marked as active), but now I screwed up and it's not bootable anymore... I'm trying to fix that now.

In a meanwhile I fixed the Windows problem and it's bootable again. I ran msinfo32 for the installation mode and it says SMBIOS version 2.4.

I just wanted to get access to Windows partition in OS X or even to add to Parallels, but doesn't show. The only partition showed is the System Reserved.

Can you post the Fdisk for both disks after you fixed the issue? Please also post the output of

sudo dd if=/dev/rdisk1s2 count=1 2>/dev/null | hexdump -C

This will show us the first header block of the Windows partition.

sudo gpt -vv -r show /dev/disk1

This will show us the GPT layout of the disk.

Can you run diskutil repairDisk disk1 from OSX Terminal? Your GPT has a CRC error and your MBR looks is non-standard and may require a rebuild, after the GPT error is corrected.

But if I do diskutil repairDisk disk1 wouldn't that erase my Windows partition and Data partition, since they are on that disk? When I run on Terminal it says Repairing the partition map might erase disk1s1, proceed? (y/N) and one thing is for sure is that I don't want to erase the disk, since all my data is storage there and Windows is working fine when I boot the MBP and press Opt key.

There is no other way around? Just to get access to my Windows partition or at least add it to Parallels or VMWare. I will barely use a VM to run Windows on Mac, since I just need Windows to work with Autodesk Revit or 3D Studio Max and for that I prefer to natively boot to Windows. It's just to get access to the files just in case if I need it and don't have to reboot.

But thanks for your help, at least this might help someone in the future as well!

It ***** cuz my Macbook Pro mid2010 don't allow to use an external dvd drive to boot any OS or even with an usb stick.

Please tell me that you have a solution to get Windows back up again and bootable! I'm using this forum on my phone now =/

We can try, provided the system reserved and Bootcamp partitions can be separated and tested. My suggestion is to leave the SSD out of the Mac. If you have an external enclosure, we can use the SSD to boot from and look at the SSHD and correct it if necessary.
