    Help, I deleted partition needed for booting? Added a new drive


    I put in a new sata drive, went to disk management.
    I made a mistake and deleted a small partition from the first drive that apparently windows needed to boot?

    I have an install disk, what can I run to fix it?

    fixmbr? something else?

    new sata drive has 1 or more partitions now? None of them has been marked ACTIVE by you?

    Boot from the win7 install disk and do the shift+f10 trick. See Command Prompt at Startup

    In that Command Prompt window do:

    Code:
    diskpart
    select disk 0
    list part
    select disk 1
    list part
    exit
    Is disk 0 or disk 1 the original boot disk?

    Also:
    Code:
    diskpart
    list vol
    exit
    Which volume from the list (C, D, E etc) is the real win7 partition? Look at the label, size.

    Actually we're doing System Reserved Partition - Delete
    How the heck were you able to delete a partition that holds bootmgr and bootmenu? Normally that's impossible!! At least from within win7.

    I dont know, it was gone, the reserved partition because I deleted it.
    I remember seeing it as device e: said was system reserved and was large so deleted it.
    Yes, I did, deleted it by clicking and deleting the partition.

    I got it fixed by booting cdrom win7 setup.
    Drop to command prompt.
    ran bootrec /fixboot and bootrec /fixmbr

    I may have been able to see it and delete it because I had dual booted win7 with ubuntu linux.
    And now have 101mb unallocated at front and 53gb free and oddly 8gb at the end.
    Ubuntu was the 53gb free.

    before I do anymore damage, that 53.34gb and 7.99gb could be combined right?

    That 8gb at the end confuses me, windows is not using it, no drive letter. And not much info if I right click.
    I can remove it but that is all I can do with it. It was I think a system file ubuntu partition. Yes that was it. You can setup ubuntu with separate /home from /root file system.

    Since your C partition is active, you can run startup/repair 3 times from the installation/repair disc (reboot after each time). It should repair the bootmgr.

    I see now what that 100mb partition is.
    100 mb wasted space is what it is for me.

    What would you do if it was your PC?

    I would refer you to the following site for a 3rd party tool to resize a partition;
    Best Free Partition Manager Freeware and free partition magic for Windows 7, Windows 8, Windows Vista and Windows XP 32 bit & 64 bit. MiniTool Free Partition Manager Software Home Edition.

    After downloading MiniTool Partition Wizard, visit the following link;

    It is working, boots up ok, do I need to do it 3 times?

    What will that do that it does not have right now?

    Is something still broken?

    I will likely keep the other partitions and reinstall ubuntu Trusty 14.04, I like to dual boot sometimes.

    If it boots, you are OK. Just leave the 100MBs alone - it's not worth mucking around for that itty bitty amount of space.

    Should you, however, use Partition Wizard to reclaim the space, you have to use the bootable CD version. And make an image of C before you start because I once lost partitions due to a small mistake using Partition Wizard.
