    create or repair boot sector on an already installed windows disk


    Hello,

    This is my problem

    - I added a SSD to my computer.
    - Windows 7 Home was installed at my C-drive (harddisk)
    - I succesfully installed Windows Home at my new A-drive (SSD)
    - When I startup I can choose between two Windows 7 installation
    The first is the new installation, the second is the old one

    - Now I want to remove my old C-drive
    But when I do this Windows does not start up.
    I tried booting from the installation DVD, tyring repair, but my new installation does not appear in there, so I cannot repair that installation.

    Someone told me I had to repair the bootrecord on my new SSD, but I don't know how.
    I DON'T want to reinstall windows. I only want to repair or copy the bootrecord on this new SSD so that I can remove the C-drive

    Whenever I replug the C-drive everything still works fine. That disk and that installation is fine as well.

    Can I copy it from that installation?

    Thank you

    Hello Floris I don't know if either of these will help you our but worth a try
    https://neosmart.net/wiki/bootrec/

    or

    Use Bootrec.exe in the Windows RE to troubleshoot startup issues
    not having to have to do either of these I am not really sure but they do look similar to each other.

    I just found this too wasn't sure if I had seen it but read this MBR - Restore Windows 7 Master Boot Record

    NB Remove the old drive first

    Post screenshot of disk management please. The problem most likely is : The old disk has the bootmgr and bootmenu.
    the screenshot gives me enough information to show that.

    If win7 did format the drive the MBR and partition bootsector are fine! No reason to think he's got a faulty boot sector.

    Bootmgr - Move to C:\ with EasyBCD be sure to move bootmgr to the SSD partition! If successfully detach the old disk and test. Post results.

    If it boots fine: shutdown, power off and and attach the old disk again. Boot to win7 on ssd. Now make the primary partition on old disk INACTIVE see Partition - Mark as Inactive

    Reboot again. Post results. Post disk management screenshoot again.
