Help!
After upgrading to Yosemite, and now when I ALT Boot Windows 7 and Recovery partitions no longer show up. Is there any ways to get my data in the disk back?
The Disk Utility is like this:
Following Loner T, I tried some commands, It shows like this:
Failing loss the material, here I seek help from Loner T
Thanks ! Waiting online
MacBook Air, OS X Yosemite (10.10), dual system: mac and win7
Why do I just see three by pressing the "Alt" when booting? should we go back and have a check?
In the Disk utility, It shows like this:
Macintosh HD
1. Macintosh HD
2. disk0s3 (inactive)
15.6GB Kingston data traveler
1. its-name
I reboot the computer using USB driver, now I post some output of commands:
It seems that output of the "sudo gpt -vv -r show /dev/disk0" are not changed after our process today
Hope this can be useful
Please post the output of sudo fdisk /dev/disk0.
The GPT and MBR are now in Sync. Does Windows come up? It may need startup repair.
Does OSX from the internal drive work? If not, it can be re-installed without any further modifications to Windows or any of your non-OSX files.
On page 3, these steps were executed (it should be n, 3 not n, 4 in the steps below).
sudo gdisk /dev/disk0

The output is as follows:
And the commands I used to excite are as follows(page3):
The commands are correct. Remove the USB. If you power off /power on and hold the Alt Key, what do you see?
there is the option of windows (only ) when remove the USB drive and press "Alt". but when trying to enter, it shows "missing operating system".
For OSX, I can't enter the OSX 10.10 in the internal drive.When I trying to do so, I enter the USB drived system (MAC LION)
In addition, how to " startup repair" the window?
when I startup the computer with pressing "alt" , I can see "windows" (only this one), but fail to enter showing " missing operating system"
For startup repair you need the Windows installation media, and boot from it to repair the Windows installation.
How long steps do I need to make it work? .......
does startup repair the windows can also get the mac system back ? It seems hopeless 😟
also,can startup repair bring the risk of deleting the data in windows partition
For Startup Recovery I suggest you take a look at http://windows.microsoft.com/en-us/windows7/products/features/startup-repair.
No, OS X and Windows are unrelated.
Unless you make a mistake during Recovery, it should delete any of you data.
You can re-install OS X without making any changes to Windows to get that side working. You have done it once on your USB already.
HI,Loner. I wonder is there something wrong with My boot file which is a shell script can control the guide (like the "grub.cfg" in the Ubuntu) for failing entering the mac system from internal drive? If so, can we just change here instead re-installing of Mac. As you say, repair windows cannt bring MAC back.
I feel there is something wrong with my boot file(a shell script file can help control the system boot). Do you know is there any boot file in the MAC system(like the "grub.cfg" in Ubuntu system)?
As you say, after repairing the windows, I still need re-install the Mac. It seems a big work. I see some thread who lost files after repairing windows

If the OSX installation on the internal drive does not show up, the quickest and easiest way is to re-install OSX. There is an OSX command called bless (https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man8/bless.8.html) which can be used to make an EFI OSX bootable.
according the Disk utility the Win7 and OSX are both existing, May be we just need few command to fix up the boot file to make the two system show up
On your machine Recovery HD and everything after it was deleted including Apple_Boot to get Windows to work, as shown by your diskutil list output. The only method to get it back correctly is to re-install Yosemite.
Can you post the output of diskutil cs list?
On a working system, this is what I have...
