    Partition table lost after Hibernate


    Hey all,
    Strange thing happened. After my last hibernate, Windows will not boot. After a few attempts to fix via Safemode, Hiren’s boot CD with MBR utilities, and a startup repair, my Win 7 partition is no longer listed in the MBR.

    How can I get it back, or should I just reformat?

    nope. Can I use a bootCD like Hiren's or a Live CD to access cmd and go that route?

    Reboot your PC. Press and hold down F8 until you see the Advanced Boot Options screen. Choose the option 'Safe Mode with Command Prompt'. Enter the commands once you're in.

    Found this article:
    Partition recovery - understanding and recovering partitions.

    maybe that will help you.

    F8 won't get me into safe mode. How else can I get in?

    Update: Ok, I'm into Safe mode with command via (F4).

    What directory do I need to enter these commands into, because I keep getting a cmd"is not recognized as an internal or external command..." error. I have tried in C:\, C:\Windows\System32

    also, some people have listed the commands on here as Bootrec and some with bootrec. Which is correct?

    You can try Hiren's BootCD if there are no other options. There are Master Boot Record (MBR) tools included in the disc.

    Rebuild MBR


    Hi All,

    For some unknown reason I have lost my MBR and Windows won't start

    The partitions I have are:

    Disk 0 Partition 1: System Reserved 100MB
    Disk 0 Partition 2: Windows partition 50.8GB
    Disk 0 Partition 3: Docs 247.2GB

    Disk 1 Partition 1: Backup

    How can I get Windows to recognize Disk 0 Partition 2 as the Windows partition and boot off that? Do I have to reformat?

    I have Hiren's bootCD if anyone knows how I can use it, or I can rebuild the MBR from scratch, just could use some help.

    Thanks!

    Hello nabilalk.





    Before we make any specific recommendations will you please post a snip/screen-shot of the entire disk management drive map with a full description as to which drive/partition is which, so we can see what you have going on as there may be a fairly simple way to resolve the situation.

    In the Windows start menu right click computer and click manage, in the left pane of the "Computer Management" window that opens click disk management and post a snip of that.
