    Your GPT is corrupt for some strange reason. This is from the first page of this thread. You now have a JHFS+ volume, which is not CS volume any more.

    This does not match what you currently have as you can see and compare.

     

    In Recovery console, are you allowed to repair the disk? Please back up Windows first to an external disk.

    No I cannot repair it. See my first previous published screenshot where i tried to verify and repair the disk. Can a virus or malicious software in windows affect the mac partition?

    Do you have a Time Machine backup of OS X?

    Yes I have but not with me now. I backup on a home server but I am not at home these days. These backups are previous to the manual partition tweaking of last week.

    It is unlikely that a malicious piece of software changed your partition table. Such changes make it harder to steal information. Can you wait till you get home to fix this? Windows should continue to work.

    That's OK i will try coming weekend but if I restore from a time machine back up can I do that only on the 85 GB partition? When I was trying to do a fresh Yosemite installation it was asking me to do it on the 35 GB windows volume. It can't see the Mac volume anymore. Further would a restore with a backup previous to the fix I did last week to enable the  Windows partition not disrupt again windows?

    If you have an OS X TM backup, you do not do a full restore, but a Migration from your old TM backup.
