Installed Yosemite (OS X 10.10), Windows 7 Partition/Bootcamp does not work.

Hello,


I recently installed Yosemite (OS X 10.10). When I was going to boot my Windows 7 partition (by holding down 'alt' when booting) I realized that it dissappeared.


I did not back up my mac as I thought this would not effect my bootcamp. Needless to say, I regret upgrading to this yosemite. I have very important files that i need to recover on my windows.


Could someone please help me with step by steps on how to recover my windows. Please let me know what info you need and how I get these info. Please send me a message or post if you could kindly help my situation. Thank you


Here is the info of my mac

When I checked Disk Utility this is what I found:

The Boot Camp partition is not there. But there's a new partition (Have not seen it before) called disk0s4


What should I do to get the Windows 7/Boot Camp partition back?

Sorry. This fell off my list. 😟


Will you be able to use Testdisk (http://www.cgsecurity.org/wiki/TestDisk) and GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) and start with a Testdisk scan.


Please see http://imgur.com/a/PjmnK for the starting Testdisk. If you download Testdisk in your download directory, you can start it with


sudo ~/Downloads/testdisk-6.14/testdisk /dev/rdisk0


Your version number may not be 6.14, but may be higher.

Feb 24, 2015 5:14 AM in response to k3ntrol

For each of the MS Data partitions, use 'P - List files' . Please be careful with keys. Start with the MS Data that is highlighted, it is the most likely candidate given that your GPT4 is at


243681280 244715520 4 GPT part - EBD0A0A2-B9E5-4433-87C0-68B6B72699C7


This is about 57K sectors within your Recovery HD, so you may lose Recovery HD temporarily.

Hi All -


I have the same kind of problem as described.


There are a few things that are different though.

I have two partitions one GUID and one NTFS using Tuxera NTFS version 2014 driver.

I had Windows 7 64 bit professional installed on a separate partition.


I ran W7 in two ways.

1- boot camp with the option boot key and selecting the windows 7 drive

OR

2 - Via parallels


After the yosemite upgrade, the boot camp option disappeared, the parallels option is fine.

I suspect the MBR is screwed up in the bootcamp side.


Following the suggestions above, I have done some of the diagnostics -

If anybody has a suggestion for restoring the ability to boot from the option key at startup I'd really appreciate your help.


The other option is to

1 - backup the windows 7 disk.

2 - Remove the partition

3 - Add back the partition

4 - Install Win7 again via boot camp

5 - Restore partition that was backed up in Step 1


All of the is really too much work for the few times when I need more CPI power than I can get from a parallels VM


Thanks

Since the NTFS header is intact, you may be able to run a simpler fix, you can try the following steps. Please ignore the i386 boot error message in the following steps. The following steps change the Windows entry (MBR #4) to be bootable and the MBR Index ID to be NTFS (it is currently FAT).


sudo fdisk -e /dev/disk0

p

setpid 4

07

flag 4

p

w

y


Reboot and test.


Test 1 - Can you see Bootcamp Volume in Finder?

Test 2 - Can you files in Bootcamp files in Finder?

Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?

Test 4 - If Test 3 is successful, select Bootcamp, and click on Restart.


If you see a black screen with a blinking underline cursor in top left corner and Windows fails to boot, please post back.

Yes

>Test 2 - Can you files in Bootcamp files in Finder?

Yes

>Test 3 - Can you select Bootcamp in System Preferences -> Startup Disk?

No - I have never been able to do this. Lone ago when bootcamp was first released it was known that since this is a ntfs partition it would not shown up in the startup disk selector

>Test 4 - If Test 3 is successful, select Bootcamp, and click on Restart.

Great. Now I need to test that the parallels invokation still works! Great - All fixed with one command.


The only other weird thing is that the recovery partition is from Mavericks. Not sure why the upgrade to 10.10 did not update that.

Apple provides a read-only NTFS driver for OSX and Windows/Bootcamp. If there are any third-party NTFS drivers installed on the OSX side (Tuxera, Paragon, NTFS-3g, NTFS-3, NTFS-Free,....) then System Preferences will refuse to show the Bootcamp drive. This is what i have on my MBP (I am running 10.9.5 now).
