    BOOTMGR is missing after altering partitions


    I have a Dell Inspiron 620 with windows 7. When I first got the machine I copied some stuff from an old hard drive on to the new one. I created a partition for the old stuff called "old disk". Recently I realised I was hardly using the the second partition so I decided to merge the two. I couldn't do it though. First I shrank the old disk, then I was trying to extend the c drive but it didn't work. I used the windows disc manager and also a third party program.
    Anyway, long story short when I turned on my computer this morning I saw BOOTMGR is missing, press control+alt+delete to restart. I'm not sure what to do. It looks like that file got misplaced or the partitions got messed up. Windows won't boot. I have no Windows 7 boot disc, there is no repair your computer option in advanced boot options. I have a laptop running Win 7, maybe I could get the right files off it or create a system recovery disc. The trouble is the laptop has no dvd drive.

    To do what Littlejay said above, you are going to need one Win7 installation USB drive (as you cannot burn disks).
    The first two steps of this tuorial give you a clean ISO file you can burn in an install disk, and tell how to place it on a USB pendrive.

    Then follow the tutorial Littlejay posted

    What did you exactly do to make it unbootbable? So what did you do after last succesfull boot from harddisk? Repairing the thing is quite easy, but maybe some other things are gone as well... but I don't know what you did!

    "there is no repair your computer option in advanced boot options"....?
    hmmmmm... if bootmgr is missing there isn't even a bootmenu, so no advanced boot oprions at all!

    • Did you remove bootmgr yourself (most unlikely)?
    • Did you mark another partition "active"?
