    Unknown filesystem, Grub edits and then HPFS-NTFS, can't boot anywhere!

    People, I am in deep need for help. Hello at first.

    I was cleaning my PC (folders) while working on Windows 7 (64-bit). I don't know remember actually what I did, but might be I somehow by mistake deleted Ubuntu folder, which was installed in dual boot with Win7 at the disk C (1Tb drive), disk D is for other media files.
    Then I went out to clean pc from dust and so. (it's cold here, -9) But PC was already cooled down.
    When I returned, I checked all cables inside before switching on PC. (disconnected drives happened earlier) And then, suddenly, where usually has been OS boot choose screen (Linux, advanced options, memory test, Windows 7) I got error message saying:
    "Unknown FIlesystem"

    Then I went for UBUNTU Live CD, booted in searched for problem, restarted, ejected usb (set up as live cd) and tried to run boot screen again, it gave me options as usually to choose OS, I chooesed WIndows 7, but then everything freezed on Windows 7 start up screen.

    Then I googled for that and found that there might be something wrong with GRUB because of possibly deleted Ubuntu system folder. I made different tries to run this:
    http://www.linuxquestions.org/questi...rescue-781125/ and other different GRUB fix tutorials. But I think I have messed up with partitions!
    I also tried Windows 7 Recovery cd, but it gives me out this:
    ATTACHMENT 1.

    I have also tried running TestDisk, but it shows me some kind of mess with filesystems!
    There is no clear NTFS anymore, but HPFS-NTFS. (that's wrong I suppose)
    +
    I am not able to open HDD partitions on Ubuntu Live CD. (or should I) <--- [EDIT] fixed by writing in terminal sudo mkdir /media/ubuntu


    I feel that I really screwed up something.
