I am running osx 10.10.5 and have windows 10 x64 on a partition. i used a windows tool to resize the windows partition, it worked until i restarted the computer from osx to windows. is there any way to fix this without starting over?
iMac, OS X Yosemite (10.10.5)
Possibly. Can you post the output of the following Terminal commands?
diskutil list
diskutil cs list
sudo gpt -vv -r show /dev/disk0
sudo fdisk /dev/disk0
The "sudo" commands will prompt for your password, and it will not be echoed back. You may also see a warning about improper use of "sudo" and potential data loss due to "abuse" of the command.

Can you use El Capitan has deleted my bootcamp windows partition as a reference and download Testdisk and start a scan? The gap between GPT3 and GPT4 is where there is a lost NTFS header.
Testdisk is available at http://www.cgsecurity.org/wiki/TestDisk_Download .
GPT Fdisk is available at https://sourceforge.net/projects/gptfdisk/ .
I have fdisk installed. the test disk link you gave me redirects to this discussion
If I click on the Testdisk link, I get the correct location. Can you copy the Testdisk link and paste it in a new browser window?
i downloaded test disk, im not sure if it installed. so should i follow the directions in the discussion that you linked me to? or will there be differences?
Check in your Downloads directory. If the binaries are in that directory, you can use them from the Downloads directory. It does not have a Mac installer package. It will look similar to
ls -lg testdisk-7.0/

Follow the screens in the linked discussion. Please ask questions, if you are unsure of the next step.
in steps 7 and 8 i am confused as to what im supposed to do
Each user's values in steps 7 and 8 in the first set of Gdisk steps are unique. You should not use the values from any other thread. Testdisk scan will help us find values which are specific to your disk layout. Please run a Testdisk scan and a Quick Search.

is this the right one?
Can you check if you have a System Volume Information entry in this directory?
yes i do
Your partition will look like the following.
| GPT 3 Start | GPT 3 Size | GPT 3 End | NTFS Start | Sector Offset | NTFS Size | NTFS End | Sector Offset (MB) | NTFS(Gb) | Disk End | Disk Difference |
| 1085578768 | 1269536 | 1086848304 | 1086849024 | 720 | 866674681 | 1953523704 | 0 | 413.26 | 1953525168 | 1464 |
