This was one weird thing I did a few days back, xD. I was dual booting with windows 7 and windows vista. My brother scolded me to get off Vista from the computer and told me dual booting is sometimes “harmful” which I’m not sure about. So what I did was, logged in windows 7 and typed MS config in start. Went to the boot tab and deleted the vista option, restarted and windows directly loaded to 7. Then later I just formatted the drive. So the thing is I wonder how it loaded me to windows 7 without saying the boot mbr is missing..and I can’t remember if I installed vista first or 7 first. I guess I installed 7 first - not sure :e. what do you guys think? PS I posted this thread cause I see many people posting the same thread about the bootmgr going missing…. Feel free to post any opinions thanks :)

I'm pretty sure you installed 7 last. It restablished the boot partition and manager. When you deleted Vista, all you did was just that - you left the Boot partition intact, with the manager.

If you'll post back a screenshot of your maximized Disk Mgmt drive map with listings, we can look it over for you to make sure everything is correct now.

If the Windows 7 boot files were missing you'd have problems booting your computer.

The fact you don't suggests they are not.

However, post the screenshot that gregrocker asked for so that we can confirm everything is OK.

Looks strange but flags are set correctly.

Remember that the boot partition way over in the middle contains your System boot files for Win7, until they are moved into the Win7 partition.
 
why the strange?

Because the System Reserved partition is normally the first one on the drive followed by the Windows C partition.

Leave System Reserved alone. It needs no attention except to avoid messing with it. I don't now how it ended up in the middle of the drive, but it must have been moved there.

It doesn't have a drive letter so nothing can write to it, which is why you can't see it in Explorer.

As long as the flags are set correctly you should have no problems with the disk configuration. I would ask for help here before making any changes as we can give you the steps to avoid problems.

If it comes to that we can help you remove it and move the System boot files into WIn7 partition, but 100mb is hardly worth recovering unless there is another good reason.

hmm do the steps require a fresh install?

No, only marking Win7 partition Active then running Startup Repair - Run 3 Separate Times.

But I wouldn't unless there's a good reason to do so as there might be some boot sector corruption resulting from Dual Boot that blocks repairs from working. It has about a 20% failure rate.
 
You're welcome.

koolkat, it's not worth the effort if things go wrong with your system.

Just take greg's advice and leave well alone. More grief for the sake of 100MB drive space just isn't worth it.
