I've never used the software you mention using, but it sounds like it damaged your partition table (may not be Mac aware).

Perhaps you should just restore from backup.

Did you try to repair it?

all options are GRAYED out i can not even click on verify or repair option.
if i select mount disk0s11 then it says unrecognized file format
i dont know how to do that .
main problem is that it is not mounted and also not shown as Apple_HFS but in linux it is there and shows perfectly

Try repair on the top level "disk" first.

Try repair on the top level "disk" first.

it says "this disk does not contain an EFI system partition . if you want to start up ur computer with this disk or include it in RAID set.back up ur data and partition this disk"

I assume that EFI is actually there, but the software you used changed its GUID.

You can re-create it (with the correct GUID) using DISKPART.EXE

There is some info in this thread: http://www.tonymacx86.com/multi-booting/133940-mavericks-windows-8-same-drive-without-erasing.html

A bit different context, but instructions still there for EFI backup, remove, re-create, restore.
