Windows 7: Cannot fix Missing BootMngr error

06 Jan 2012   #11

Win 7 Premium 64 bit

Thanks Gregrocker.

I shall try your suggestions and come back with the results too here.

As far as expecting programs to be there, I guess I am used to Linux. When you load a single DVD install in Linux it also loads the major default programs - LibreOffice, Photo editors, a number of multi media programs etc. so I assumed that by now MS might have managed to do the same on a DVD install. I am sorry if I sound like a Linux nut. I am - but due to two factors have to continue to have access to windows. 1 - my employer still uses MS Office 2003 (government!!) and I develop VB based apps from time to time to assist people in their work. LibreOffice Calc opens and works completley with excel files, but changes some of the code in VB. Excel is unable to do the same in reverse, hence I have to use excel for Excel based apps. Thats OK because Excel is one of the programs that I do like.

2-- My Garmin GPS updater program will only work on a windows system. Next time I will not be buying Garmin

So there you have it. But as I said at the beginning I would still like to have the option available to me to switch to either OS as I please. Hence this long and tortuous process.

I am grateful for the assistance though. Thanks.

Not many people on this forum have the background to get dual boot configurations working. Try somewhere like for answers that don't involve paving over your Linux installation.

Have you considered using Linux as your only bare-metal OS and running Windows under Linux through VirtualBox or VMware? Virtualization is much less hassle than dual boot and is more than fast enough unless you need to run games or high performance applications under Windows.

I agree totally. I used to use virtualbox and run XP in it. However the garmin updater would not run in the VB, but only on an actual system. So when I got this laptop with win 7 already on it, I thought why not!. Of course you can see how I stuffed it up LOL. I think that I will ditch Windows completely however because it really is superfluous for my needs and all the video and audio editing work as well as anything else I want can more than equal or beat any windows programs.

So -- thanks all for the help, nothing worked so it's back to a better OS - Long live Open Source and the power of community excellence

Bootmgr is not supposed to be on the mbr.

Whatever gave you that idea?

Leftover references?

I suspect that there is a reference somewhere in the "boot sequence" that still refers to the old location.

Not everyone has problems with GRUB.
I have XP (Boot), W7 and Ubuntu installed (installed in that order).

The only time I have had boot problems, is when I resized and moved my OS partitions.
That totally screwed W7 because it was the OS that was moved (XP and Ubuntu were unaffected).

I'm reasonably sure that you could copy your Linux install to a safe location (e.g. external HDD) and copy it back later.
I have done it with Ubuntu (following someone else's instructions and with help from my friend, an experienced Linux user).

My suggestion would be to start again:
  • Use your Linux Live CD to copy your important data off of the W7 partition.
  • Copy your Linux install off of the HDD too.
  • Wipe your HDD.
  • Pre-partition and format it for your operating systems (e.g. use GParted or other disk manager). That should prevent the "System Reserved" partition from being created.
  • Re-install your operating systems. (make sure that you install Windows before Linux).

Here is someone else's method (using the W7 setup disc):
