Windows 7: Bootmgr is missing even after doing a startup repair

Bootmgr is missing even after doing a startup repair

Edit: Solved.

Hello everyone.

I just recently performed a clean install from Vista 64bit to Windows 7. I have two internal drives Local (C: ) and (F: ). I made sure I installed Windows 7 on my local (C: ). Everything installed fine and I got Windows 7 to work.

The problem is when I restart my computer, I get the "Bootmgr is missing". I am only able to get to my desktop if I have my DVD set to top boot device in my BIOS, AND if I have the Windows 7 dvd in it.

I searched everywhere for a solution and it seems like the way to fix this is to boot from Windows 7 and do a startup repair. I did this, but I am still getting the exact same problem.

When I am on the system recovery window , I noticed it shows my (D: ) drive (even though it is set to (C: ) but it shows the same size of my (C: ) drive.

How Do I fix this?

Zinic;

Windows 7 does not (normally) assign a drive letter to the 100MB system partition, but when using the recovery DVD/CD, that partition is given the C: moving the other drives/partitions down one letter.

Please verify that the Hard drive with Windows 7 is set to the primary hard drive in your BIOS settings ( if that is possible), or unplug the second hard drive and see if 7 boots normally?

Cheers!

Unplug the Backup Drive.
Or Flash Drive, whatever you have it plugged.

the bootmanager is missing is classic. if you had a previous OS then installed win 7 as dual boot, win 7 puts a hidden folder (called boot) in the root of the earlier OS. so when you either delete it, or upgrade from it>>> presto the boot manager that was there isnt.

You have tried a "startup repair"? does that mean a repair install?

let us know

Your F drive was probably somehow marked active or otherwise confused the installer. Unplug it and make sure C: is HDD set to boot first in BIOS, after DVD drive.

Then boot into your Windows 7 installer Repair console and run Startup Repair 3 times, as there are multiple issues to fix and it can only fix one at a time.

A repair install is run from the desktop in Windows 7, an in-place "upgrade" over itself. It can reconfigure the boot or a multiple-boot as it reinstalls the OS while saving programs in place.

However OP cannot get into Windows 7 so he needs to run Startup Repair, as all boot recovery commands are automated in Windows 7 startup repair but must be run repeatedly if there are multiple issues, since it assumes each fix tried will restart the OS and it often won't.

When you say drives - I assume you mean two completetely different HD.s?

If you do have 2 HD's, set the 7 HD first in bios HD boot order and run startup repair from the 7 dvd - it may take 3 runs.

I that doesn't work, boot the 7 dvd to command prompt, type ( press enter after command) :

Diskpart

lis vol

( make a note of exactly what it says - and post it up here afterwards)

( find the letter for the volume you installed 7 on - use that instead of ? below)

sel vol ?

act

exi

Then run startup repair - up to 3 times.

Um I had my windows 7 HD set up as top boot priority. Didn't work. But I disconnected my other HD and so far it worked. The problem I am having now is that the Windows Experience Index is not working. I will create another thread.

run "sfc /scannow" as Admin to check system files for corruption

if there is corruption which cannot be fixed, or persistent problems, run your 7 installer from desktop to do a Repair install, which is an in-place Upgrade over itself.
