Hi everyone, I recently upgraded from the Windows 7 beta to the RC. After I installed everything that I wanted I switched my computer off. The next morning I switched my computer on and the error message "BOOTMGR is missing, Alt+Ctrl+Delete to restart". I found the article and tried both the startup repair and bootrec/fixboot methods but to no avail. Luckily when I have the Windows 7 disc in, the computer starts up normally. Please help anybody!!!

Bullmember2, hello. That's a new one! It suggests that the system is looking for the BOOTMGR on your install DVD. With Win7 running, open an elevated Command Prompt (run as administrator). Run "bcdedit" and copy the output to this thread. To copy from Command Prompt, right-click in the window, choose Select All, then press Enter and the text will be in the clipboard.

Thanks for the advice, I seem to have fixed the problem though. I would prefer not to try anything else in case I mess it up again. I have three partitions on my computer, a Windows XP partition, a Windows 7 partition and a general data partition. So , what I did was I told the computer (BIOS) to boot from the Windows XP partition. Then it asked me which OS I would like and everything was hunky-dory again. I have done what you asked and here is the output.

Microsoft Windows [Version 6.1.7100]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.

C:\Windows\system32>bcdedit

Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=D:
path \bootmgr
description Windows Boot Manager
locale en-US
inherit {globalsettings}
default {current}
resumeobject {68aa2c34-f96c-11dd-8318-da4a524cb77c}
displayorder {ntldr}
{current}
toolsdisplayorder {memdiag}
timeout 30

Windows Legacy OS Loader
------------------------
identifier {ntldr}
device partition=D:
path \ntldr
description Earlier Version of Windows

Windows Boot Loader
-------------------
identifier {current}
device partition=C:
path \Windows\system32\winload.exe
description Windows 7
locale en-US
inherit {bootloadersettings}
recoverysequence {68aa2c36-f96c-11dd-8318-da4a524cb77c}
recoveryenabled Yes
osdevice partition=C:
systemroot \Windows
resumeobject {68aa2c34-f96c-11dd-8318-da4a524cb77c}
nx OptIn

C:\Windows\system32>

I would just like to point out that the XP partition is D: and Windows 7 partition is C:. Is it possible that Windows 7 installed the BOOTMGR in D:????

It's not just possible, it is certain that there is a boot manager on the "D" partition. The output of bcdedit, above, shows that the boot manager being used is at "D:\bootmgr". There is a file there that you can see, though it is a hidden system file. If you look in Disk Management (diskmgmt.msc), you should see that the partition with XP is marked as "Active" and "System". You would also probably find the BCD store on the D:\ drive, usually in \Boot\BCD. This is also a hidden, system file.

It is good to know this information. If you ever decide that you are done with XP and you just delete that partition, you will again get the "BOOTMGR is missing" message because the boot manager lives on that partition.

To clear something. Drive letters differ in XP and Vista and Win7. In my case G:\ in XP is C:\ in Win7. (My vista C:\ is D:\ in Win 7)

I object to this thread being marked SOLVED. There is no solution in here anywhere and trying to find a new thread to see if it was solved is at best guesswork.

Here is the issue and the solution:
The issue is genea has two hard drives and wants Vista Installed on one and a clean, non dual boot install of Win7 on the other. Win7 assumes dual boot and puts the Bootmgr on what it sees as the primary drive (it thinks primary drive=boot drive.) Unfortunately most new BIOS let you select the boot drive, so it is not always your 0 drive.
The solution is unplug the Vista Drive and reinstall Win7. Then Win7 puts Bootmgr where genea wants it, on the Win7 drive. Otherwise when you select the Win7 drive in the BIOS (or some systems have a Boot Manager) it will not boot and you'll get the "Bootmgr Missing" error

It is marked Solved because the OP has solved it. That means he/she does not need any more help. Doesn't necessarily mean you will get any useful info from it.

I have a same problem. I got the message Missing Bootmgr, but when I was trying to extend one of my partitions I accidentally made my data particion as an Active Drive. Are there any ways of fixing it without reinstalling windows 7? Thank you also I don't have a Win 7 disk. I installed windows 7 from my hard drive. Thank you please help
