    Bootmgr is missing even after doing a startup repair


    Edit: Solved.

    Hello everyone.

    I just recently performed a clean install from Vista 64bit to Windows 7. I have two internal drives Local (C: ) and (F: ). I made sure I installed Windows 7 on my local (C: ). Everything installed fine and I got Windows 7 to work.

    The problem is when I restart my computer, I get the "Bootmgr is missing". I am only able to get to my desktop if I have my DVD set to top boot device in my BIOS, AND if I have the Windows 7 dvd in it.

    I searched everywhere for a solution and it seems like the way to fix this is to boot from Windows 7 and do a startup repair. I did this, but I am still getting the exact same problem.

    When I am on the system recovery window , I noticed it shows my (D: ) drive (even though it is set to (C: ) but it shows the same size of my (C: ) drive.

    How Do I fix this?

    Zinic;

    Windows 7 does not (normally) assign a drive letter to the 100MB system partition, but when using the recovery DVD/CD, that partition is given the C: moving the other drives/partitions down one letter.

    Please verify that the Hard drive with Windows 7 is set to the primary hard drive in your BIOS settings ( if that is possible), or unplug the second hard drive and see if 7 boots normally?

    Cheers!

    Unplug the Backup Drive.
    Or Flash Drive, whatever you have it plugged.

    the bootmanager is missing is classic. if you had a previous OS then installed win 7 as dual boot, win 7 puts a hidden folder (called boot) in the root of the earlier OS. so when you either delete it, or upgrade from it>>> presto the boot manager that was there isnt.

    You have tried a "startup repair"? does that mean a repair install?

    let us know

    Your F drive was probably somehow marked active or otherwise confused the installer. Unplug it and make sure C: is HDD set to boot first in BIOS, after DVD drive.

    Then boot into your Win7 installer Repair console and run Startup Repair 3 times, as there are multiple issues to fix and it can only fix one at a time.

    A repair install is run from the desktop in Win7, an in-place "upgrade" over itself. It can reconfigure the boot or a multiple-boot as it reinstalls the OS while saving programs in place.

    However OP cannot get into Win7 so he needs to run Startup Repair, as all boot recovery commands are automated in Win7 startup repair but must be run repeatedly if there are multiple issues, since it assumes each fix tried will restart the OS and it often won't.

    When you say drives - I assume you mean two completetely different HD.s?

    If you do have 2 HD's, set the 7 HD first in bios HD boot order and run startup repair from the 7 dvd - it may take 3 runs.

    I that doesn't work, boot the 7 dvd to command prompt, type ( press enter after command) :

    Diskpart

    lis vol

    ( make a note of exactly what it says - and post it up here afterwards)

    ( find the letter for the volume you installed 7 on - use that instead of ? below)

    sel vol ?

    act

    exi

    Then run startup repair - up to 3 times.

    Um I had my windows 7 HD set up as top boot priority. Didn't work. But I disconnected my other HD and so far it worked. The problem I am having now is that the Windows Experience Index is not working. I will create another thread.

    run "sfc /scannow" as Admin to check system files for corruption

    if there is corruption which cannot be fixed, or persistent problems, run your 7 installer from desktop to do a Repair install, which is an in-place Upgrade over itself.
