    Missing Operating System/Startup Repair Failure


    Hi, I apologize if this isn't the right subforum but I saw a couple old posts about this in General.

    Yesterday one of my kittens knocked my laptop off my chair causing it to hit my PC tower on the way to the ground. My tower immediately froze and when I went to restart it manually I accidentally pushed the reset button instead. (It's the button on the right) Upon doing this my computer restarted and gave me the Missing Operating System error.

    Since then I have tried several things from pressing F8 and specifying the drive to boot from, to entering several commands listed here to booting from my Win7 disk and running startup repair. This final option I did a couple times last night rather uneventfully but today it failed. Under problem details it gave me this:

    Problem Signature:
    Problem Event Name: StartupRepairOffline
    Problem Signature 01: 0.0.0.0
    Problem Signature 02: 0.0.0.0
    Problem Signature 03: unknown
    Problem Signature 04: 0
    Problem Signature 05: unknown
    Problem Signature 06: 1
    Problem Signature 07: unknown
    OS Version: 6.1.7600.2.0.0.256.1
    Locale ID: 1033

    I don't know if this information is relevant or helpful but I thought I'd include it anyway v0v

    edit: I just told Windows to go ahead look for a solution and it claims I have an attached device that needs to be removed, which I don't.

    edit2: Would a total reinstallation of Win7 fix the problem?

    Any advice is appreciated.

    First, I would open the tower and check to see if all the connections to the hard drive, etc. are still secure.

    Yeah I did that too and everything seems ok but I'm not entirely sure. I have a couple buddies who build and might get them to look at it.

    Boot to system recovery options (OPTION TWO) System Recovery Options and select "command prompt"

    Code:
    dir  c:\users
    dir  d:\users

    Hi there.

    Ensure that the boot disk's partition is marked as ACTIVE although why this should have changed ???? == Beware of "CAT POWER" !!!!!.

    for dir c:\users I get: The volume does not contain a recognized file system. Please make sure that all required file system drivers are loaded and that the volume is not corrupted.

    for dir d:\users I got: The disk structure is corrupted and unreadable.

    Done, although I have two ~120 GB SSDs that have always acted as one disk and this failed on the first saying 'There is no partition selected' when I tried to select one but it worked for the second disk. Entirely not sure if this makes a difference.

    Code:
    diskpart
    list vol
    exit
    What drive letter has the win7 partition (look at the size to determine what it is)

    Are the two SSD's mirrored or striped? So ... is it RAID 0 or RAID 1?
