Boot manager is missing, will not boot without the windows 7 install disk in the drive

    Question

  • I’ve got a strange one on my hands here. I can not boot into windows 7 without having my windows 7 install disk in the drive at boot up and wait past the hit any botton to boot off of cd. If I try to boot without the disk in the drive I get the boot manager is missing error.

    Also I can get windows 7 to recognize one of my SATA drives.

    I have a pair of drives in raid 0

    A 160 gig drive windows can see

    A 250 gig drive that windows can’t see

    My mobo is a Abit   ix38 quadgt

     

    Thanks,

  • I've seen a couple of these and would suggest first running Startup Repair from the installation DVD.
    If that doesn't fix it, then you're going to have to delve into BCDEdit (which is beyond my abilities)

    And what will happen if You just change the boot sequence in BIOS,
    setting HDD as the first boot device instead of CD/DVD?

  • usasma,

    Thanks I will try that out now.

    Vlad0,

    If I set the HD as first boot device I get the same boot manager is missing error.

    Thanks,

  • Usasma,

    I tried that and windows could not detect any problems.

  • I am having the same problem... Have you tried doing what is says for windows Vista? I am going to try a few things and will post what happens.. If you have fixed yours I would love to hear how..

  • DId you adjust your hard drive connector position on your mother or did you setup a raid after the install of RC 7 if so you then need to do a repair using the installation DVD or you might have to reinstall it.  changing config sata from IDE to AHCI to RAID in your bois will cause this problem 

    Tuesday, May 26, 2009 3:23 AM
  • Thanks for the reply.  No I set up the raid a while back. Intact everything used to work fine and boot normal when I ran Vista and I didnt change anything since then.  All I didnt was reformat the raid partition from the windows 7 install disk and then installed on the same disks.
    I tried to run the repair mode and it didnt detect anything wrong. I know this has nothing to do with my install disk because I used the same disk to install 7 on my laptop and that runs fine. 

    Thanks,

  • I know there is a hotfix for this through the Windows technet a patch for vista that will allow a dual boot mode for XP and Vista installed on the same drive

  • sprogis,

    If Windows isn't able to repair the problem on its own, you might try EasyBCD .

  • One think at a time:

    To fix the hard drive go to control panel - all control panel items - select administrative tools - computer management on the new window go to storage and then disk management, from that page you can see your hard drives and you have the option to enable or assign a letter path to that hard drive.

    To solve the boot issue:
    1. Put the Windows Vista installation disc in the disc drive, and then start the computer.
    2. Press a key when you are prompted.
    3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next .
    4. Click Repair your computer .
    5. Click the operating system that you want to repair, and then click Next .
    6. In the System Recovery Options dialog box, click Command Prompt .
    7. Type Bootrec /RebuildBcd, and then press ENTER.
      • If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type Yes. A confirmation message appears that indicates the entry was added successfully.
      • If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.

    Bcdedit /export C:\BCD_Backup

    ren c:\boot\bcd bcd.old

    Bootrec /rebuildbcd

    1. Restart the computer.
    Good Luck

  • Hi e_sand,

    I did what you wrote and because Bootrec.exe could not locate any mising Windows Installations I tried removing the BCD store to recreate it.  I did

    Bcdedit /export C:\BCD_Backup

    followed by an enter and then went on to the next step

    ren c:\boot\bcd bcd.old

    after I hit enter it said that it could not find the file specified.

     

    So that is where I am at...

     

    Anything else you can recommend? \

    Thanks

  • This is an almost identical description of my windows 7 problem. I found boot files on an empty sata drive. If I disconnect that drive I can't boot into win 7 at all. The boot to cd "repair startup problems" gives a message that it is not able to make a repair. Reconnect the drive (Win7 cd in cd drive) win7 boots. Can't figure out a way to fix it with Easy BCD. Of course some of the files are in use so I can't copy the files to the C: drive folder. Tried to do a win7 upgrade install in windows and error message "Can't find necessary installation files" I'm starting to look for a fuse to light or a plunger to push.. This is the second fresh install. Other than this boot problem everything in win 7 works perfectly. This is a Tyan S2866 AMD Opertron 175 with 2xGeforce 8600Gt graphics in SLI.

  • Hello

     

    Please try this:

    1- boot the windows 7 CD

    2- repair

    3- click on the cmd option

    4- diskpart list volume

    5- make sur that c:\ is referencing the volume that contains windows directory, if it is not the case change it to c using assign letter command of disk part

    6- now, you are ready to rebuild from scratch

    7- go to c:\windows\system32

    8- run :    bcdboot c:\windows /s c:

    9- shutdown -r -t 0

    Everything should be ok.

  • Thank you Haithem, that worked like a charm, grub2 wiped out the loader and that fixed it.

  • Mahalo Nui Loa Haithem! Worked for me too! Win 7 crashed after SP1 update, had to run DISM, then the drive went bad too! I just finished restored (4 hours later) from a Ghost Images (which took 9 hours to create). This was a life saver!

  • You are a Star Haithem!

    I had just spent the good part of a day loading my new laptop, and after installing Windows 7 x64 SP1 from the Windows Update it now failed to boot.  I tried everything and was about to start again when I found your suggestion.

    I worked a treat.

    Thanks

  • I have read all these possible solutions with interest as I have had the same problem since last Friday.  Nothing has worked so far.  I did have great hopes
    for Haithem's solution but am having trouble with it no doubt due to my unfamilarity with the particular commands used.
    I did sort out that I had to type diskpart  <return> and then list volume plus the need for exit to return to the usual command frame.
     However, Ihave the system reserved partition listed as C: and the windows directory in D: . The help for assign (and remove) said
     I cannot use them with a boot or system partition so I could not remove C: from the system reserved partition and change the D: to a C:.


    Nevertheless, after exiting diskpart,  I did try the next part by going to D:\windows\system32 and following the instructions with a D: instead of a C:
    everywhere.  Although the sequence completed OK when I tried to restart without the boot priority on DVD/CD I still got the dreaed BOOTMGR missing.
    I have looked at my disks and I have a copy of bootmgr on both the system reserved and system partitions.

    Can anyone offer a possible explanation, please?

  • Boot back into Windows Command Line and run the following commands:

     

    • BCDEDIT >> c:\custom_bcd.log
    • c:
    • cd boot\BCD
    • DIR >> c:\custom_bcd.log
    • d:
    • cd boot\BCD
    • DIR >> c:\custom_bcd.log

     

     

    Then save the custom_bcd.log file to a usb drive and place in a technician's computer. Open the file in notepad and display the results here.

  • Thank you for offering help _JoeG

    When I put in the first of your commands I had a display of its contents.

    When I carried out c: then cd boot\BCD  I had the response Directory is invalid [although I have checked the system reserves partition and it should be valid.]  I had the same response from the second such command in D:

    I have not found out yet how to transfer the custom_bcd.log file to the usb drive, old MSDOS commands do not work so I shall have to lokk it up but, when I logged in to my computer via the DVD boot route I found two copies of custom_bcd.log on the system reserved partition root.  I append them below in case they help. (There was no such file in the system partition.

  • Ok, I have some malware that messed with the bootloader.  My question is "how can I change the disk to be the correct one 'C:' if assign won't allow me to rename system disks?"

  • Haithem:

    You suggested the only solution that has worked for me.  That's great, and I give you profuse thanks!!

    I have been frustrated for a week trying to repair a "bootmgr missing" error.

    For the edification of others with the same problem, I could not get the boot process to locate the boot manager when booting from the hard drive, but it would work when the system disk (or recovery disk) was present in the CD drive with the CD drive selected as the first boot device. Pressing a key for booting from the system disk was not necessary.  The BIOS boot priority was set to CD as first with hard drive as second.  With a system disk in the CD drive (but without selecting it with a key press) boot worked.  If the system disk was removed, boot did not work.

    Friday, October 21, 2011 8:01 PM
  • I am having a similar problem as those above, but mine is a little different. When I restored my backup, the restore first created a folder called F (the drive letter on which the backup was stored), and then restored all of the data.  So my root directory is no longer c:\ but rather c:\f\

    How do I get rid of the f:\ folder so that everything lives on the root?

    Thanks

    Stephen

  • Was having the same problem and tried a number of the suggested solutions (i.e. startup repair, BCDBOOT command, etc.)  to no avail. Ultimately what it came down to for making it work was the boot order priority in the BIOS.

    When set to this sequence I had the problem:

    1. Windows Boot Manager

    2. SATA DVD ROM

    3. SYS_RAID

    When changing to this sequence it now works as expected:

    1. SATA DVD ROM

    2. Windows Boot Manager

    3. SYS_RAID

    Hope this works for someone else banging their head on this one.

    It took me some time to find the right instructions but your information worked. After following these steps I still got the bootmgr is missing error but at least this time when I booted from the Win7 DVD my drive actually showed up (previously it didn't) and the startup repair function was finally able to make the drive bootable.

    Luckily this is just a test system I use to try thing out on. I used Acronis True Image WD Edition to make a disk image which I put on an external HDD. I then booted from the Acronis bootable rescue disk and pointed it to the image just to test if this program works correctly (before I bother installing it on my main computer).
    It put all the files back onto the HD but ended up making it unbootable.
