Windows Will Not Boot

I have tried several things I have seen on other discussions, from many different websites, and I still cant get Windows working again.

Whenever I think I am close to fixing it, it says "Missing operating system". I have done startup repair, but it won't work.

It started when I tried to resize my OS X partition if it helps. I noticed a guy named 'Loner T' seemed pretty good at this, if he is available I would like his help.

iMac (21.5-inch Mid 2011), OS X Yosemite (10.10.3)

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.

You have a missing/lost NTFS partition in the gap between GPT3 and GPT4. Can you use Unable to boot windows bootcamp after updating to yosemite as a references and download Testdisk and GPT Fdisk and get started with a Testdisk scan?

Please post a screen shot of Testdisk Quick Search output once it is available.

Already have gdisk, I'll download and get started with Testdisk right now.

EDIT: Do you have a bitcoin address? I wanna send you a bit to thank you, won't be much though, as I cant afford to give much away.

Yes, please let the Analyse Sector percentage get to 100%. This can take a while since it is a sector-by-sector scan for any missing headers. You should first see a list of unrecoverable partitions, then a list of partitions. We are interested in MS Data entries which are at a start address higher than and close to 137218320 sectors.

This is a list of unrecoverable partitions. Press Enter to Continue and you should see a list of recoverable partitions.

Do not use left/right arrow keys anywhere on this screen, use only up/down arrow/cursor keys..

Please use 'P' to list files in MS Data entries at 153517815. Ignore the smaller MS Data entries. The next interesting one is at 294649856 as well as the next one after that, which is another 7 sectors away.

(It would have a been easier to work with text versions rather than screen shots. 😉 ).

Crap, I went down to list the thing at 153517815, and it said filesystem not found. While going down to 294649846, I accidentally pressed something and went back.
