Windows 7: BOOTMGR is missing?

BOOTMGR is missing?

Hi,

I just finished installing Windows 7 x64 7068. This PC already has XP on a different drive (not just different partition). The Windows 7 drive is set to boot first in BIOS.

After the first reboot I got the "BOOTMGR is missing, ctrl+alt+del to restart" message. If I boot with the XP drive, there is an option for Windows 7 and I can log on with that.

I used the startup repair tool on Windows 7 DVD but it did not detect any problem. Tried easyBCD to reinstall the Vista bootloader but that didn't fix it either.

How can I fix this? And how should I install Windows 7 so that each drive can boot on its own? I can select which drive to boot quickly after POST so I don't want the 2 OSes to tangle up like that

Thanks.

You will need to boot from the xp drive that is where the boot manager for all windows operating systems on your machine is located.

Well I played with it for a bit... Disabled the other drives in BIOS then repaired with Windows 7 DVD. Now it finds the problem and fixes it.

Technically there was no problem until you disabled the other drives and 7 could not find the boot manager. When you install windows 7 it replaces the XP boot manager on your XP drive, that is what will be used to select which operating system you wish to boot. Disabling drives and installing a boot manager on each drive for each OS is not the norm.

Put in your 7 DVD (or USB key) and press F5,6,7,8 (always forget which one) and choose to repair the computer. This might take a few times but it should repair the lost bootmgr and you should be good to go

can you explain in detail how you did this... I have the same problem and with unplugging all other HDDs and repair-reboot-repair-reboot 5x I still get this:

Hi,

Set your hidden and system files to visible (in explorer -> mapoptions)


Copy the bootmgr file from the N: drive to the C: drive manually.

Next in bcdedit

change "device partition=N:" to "device partition=C:"

That's it

New hdd new win 7 install missing boot manager

Ok , i have a hp 2 yr. Old comp with 6gigs ram brand new wd hdd 500 gig
(i do have other hdd's disk connected to system with vista and xp systems installed on them however i have the new wd installed via bios setings as primary hdd . Installed win 7 to new wd hdd and installed ok until i rebooted . (this is after removing install disk from dvd drive ) i get the missing boot manger message. Odd thing is i can put the win 7 install disk back in and reboot and win 7 operates normally.
Alsost like the cd's with games on them were you had to have the cd in drive to play the games.
Whats happening ? Does the install put the bootmanger file someplace other than drive "c" . And how does one rectify this problem?

I'm thinking of removing the other hard drives and install win 7 again with only the one wd hdd installed and see if that does the trick.
Also the new wd hdd that i originally installed to didn't have an operating suystem installed on it

How to edit in bcdedit? And what file(s) to move?
