Windows 7: Missing Boot Manager can't be repaired – How to, please.

Once the computer begns it’s next restart, press F8 on your keyboard repeatedly until the Advanced Boot Options screen appears. If the Windows startup logo shows up, then you will need to start over because you missed the opportunity.

Using the arrow keys on your keyboard, select Disable automatic restart on system failure and press Enter on your keyboard.

Lets try to get inside Windows 7 first to see whats going on.

You said you can't plug your Win7 HD intto SATA3 which was only one idea I proposed, so just leave it where it is, unplug all other HD's and run the Repair.

Here are the results.

I got two blue screens a little after Startup Repair begun. I haven't had a blue screen for ages. On the blue page there was a reference to check if new hardware or software was properly installed, but I had not made any change, of course.


Then, I run Startup Repair three times without repeating the blue screens with the usual results:


Root cause found:
Boot status indicates that the OS booted successfully.
(Not true)
and

Root cause found:
Unexpected changes to system configuration might have caused the problem.


There was also the line saying that the last good boot had been on October 28.

I started Windows normally, and after the shrinking/growing logo it rebooted by itself. Next, I tried safe mode and it also rebooted.



Then I repeated the whole thing from the beginning getting exactly the same results, including the blue screens.

Did you catch the stop code on the BSoD?

Try tapping F8 and if it won't boot into Safe Mode at the error message don't press Restart instead press Shift F10 to see if a Command line opens.

If so, type compmgmt.msc to open Device manager, check for Device drivers in error. If none appear in error, try disabling video card to see if it will start.

Repeat with other major devices until finding one which is blocking startup.

I did not quite understand where I should use the commands, so I tried as below.
I had already tried to boot on Safe Mode, remember.
It reboots both in normal or safe mode.
The blue screen didn't appear again.

I tried Shift+F10 at booting, between BIOS and Windows. A command pront opened under this text:
Edit Windows boot options
Path: \windows\system32\winload.exe
Partition: 1
Hard Disk: adf0adf


I typed compmgmt.msc there, but continued booting; and rebooted by itself, as always. However, compmgmt.msc is on the system32 directory.

Then I tried compmgmt.msc with the DVD on the command prompt after loading the drivers, but it is not recognized as a command. I tried also on C:. Just the same.

I could not open Device Driver. What have I done wrong?

Have you actioned 'Disable automatic restart on system failure'? otherwise you'll be in an endless loop of reboots.

How can you access System 32 to see compmgmt.msc? Can you open it there?

If so, open Device Manager to check for error states. Disable display adapter to try restart.

I can't access anything in the Windows 7 installation because it doesn't boot. I only could if from the command line. I can access Device Manager on the XP installation because it boots, but this small installation has no problem, no blue screens, nothing, and in Device Manager everything looks OK. If I could access the Win7 system, I could do as you say. Isn't there a way? I believe there is a way, but I ignore how.
