I’m running win7 x64 and OS X on MacBook air. Yesterday i made regular bootcamp back-up. When back-up is processing, i cancel it. After that, i can’t boot to win7.
Results of the “sudo gpt -r -vv show disk0”
Results of the “sudo fdisk /dev/disk0”
Is there any recommendation? thank you
MacBook Air, Mac OS X (10.5.1)
Make a note of the start/end, and move to the next one which allows the same thing. It may be that you will have just one. The size of this one as 2880 seems suspicious a bit.
I have list all MS data partition, there are only 4 MS data partitions that can be list

The size being 2880 makes it look like only that partition was moved around quite a bit. If you do not see any other files, these do not look likely candidates for your bootcamp.
One option, if you are willing to try, is to use GPT Fdisk (http://sourceforge.net/projects/gptfdisk/) and create a Hybrid MBR after updating the following entry to be a MS Data partition and see if Windows will come back. It may still need Windows Startup repair. Changing the Partitiontype GUID to MSData, will at least let the partition be visible in OSX and it can be read to see if you can see more familiar files.

thank you!
Does if mean that TestDisk can't finish MS data recovery?
Of course, i am willing to try.
We need to assume that your Windows was working before the TM issue, so the GPT entries are correct and somehow the partition type was the only change. If that is not the case, let me know.
1. Using GPT Fdisk, update the GPT entry to have the correct Partitiontype GUID.
2. Please see Windows 7 not bootable after upgrade for the steps to create a Hybrid MBR. Post back here, if you have questions.
Steps to update the partition type GUID of the GPT#4 entry are

And the disk4 is gray
GPT4 looks correct, but the Hybrid MBR still needs to be re-created using Windows 7 not bootable after upgrade.
I tried to follow step by step "Windows 7 not bootable after upgrade"
What i did :
sudo gdisk/dev/disk0 pressed r
pressed h
in sequence 2 3 4
pressed enter for all of them and set bootable flag for 4
w and quit
when i reboot and try to boot into windows7, It says "miss operating system"!
Do you have any suggestions? thank you very much

You may need to do a Windows Repair.
1. Put the W7 DVD in the Optical drive.
2. On the OSX side, System Preferences -> Startup Disk, choose the Bootcamp Partition and Restart.
3. When prompted to boot from the DVD, press any key and Repair your Bootcamp W7 installation.
Also please see http://support.microsoft.com/kb/927392
1. Does your Bootcamp Volume show up in OSX Finder?
2. Can you see files in the Bootcamp volume using Finder?
1. Bootcamp Volumes doesn't show up in OSX finder after updated the GUID of the GPT #4 entry to 0700
2. I can't see any files in Bootcamp
