bootmgr failure lately on a Asus Z97 during P3D session

Recommended Posts

Hi,

 

I am starting to get these "bootmgr missing" yesterday. It all started when i was loading a saved flight with the NGX and P3D2.5.

 

I have a Asus Z97-Pro motherboard with latest Bios and a SSD 128GB Windows 7 64bit.

 

Are there any simmers outhere who have experience this ? Its all new to me actually. I never had any issues of this before. 

 

The SSD is about 2.5 years. So far it only happens with P3D. 

 

I have done a system repair (startup repair) from the original windows DVD and setup BIOS afterwards . It seems like the BIOS after the crash is failing to recognise my bootdrive .

 

This time around it crashed just after landing EGLL-EKCH and about 2 hours in P3D

 

Is it a bad SSD ? (System based pagefile) (another drive has 3072mb located). FSX and P3D drives no pagefiles.

 

Thanks

Michael Moe

Lots of things to look at here:

Since it can be many things, you need to isolate the problem(s).

1. Overclock CPU? If you do, load "Optimized defaults" and keep at default speed for a while;

2. Which Sata port is used? Intel or Asmedia. You should use Intel as the preferred port.

3. With these Z97 boards, new drivers are still being rolled in. Here the principle is unfortunately the last may not be the best.Drivers to look for: Intel Sata and Asmedia, Intel chipset

4. Is your memory o'c? If yes, use the default value and test.

5. Make sure your Sata cable is plugged in correctly.

6. Make sure your Sata drive is saved as the boot drive in the BIOS.

7. Make sure you do not have another drive that would have a "bootmgr". That could cause havoc.

 

I have had a similar problem with my recent upgrade/reinstallation with a Maximum VII Formula.

It is now working ok, but it is in "test mode" as far as I'm concerned.

 

I can not pinpoint a particular item that would have caused me a boot problem. But I did all of the above and it worked..

Anyway, hope it helps.

Thanks,

 

I have checked cables and they seem fine.

 

 

Where do i see the Intel/Asmedia Port ?

 

******* i am sorry . Its a Z87-Pro board Bios 2103 (latest)

 

Memory is actually downgraded to 1333 mhz . The system just crashed in Windows as well

 

I am trying to use another HDD for swapfile to see if its related to the other Drive that had a pagefile of 3072mb

 

Thanks

You may have to rebuild the Bcd, I've had this happen before.

  1. Put the Windows installation disc in the disc drive, and then start the computer.
  2. Press a key when the message Press any key to boot from CD or DVD appears.
  3. Select a language, a time, a currency, a keyboard or another input method, and then click Next.
  4. Click Repair your computer.
  5. Click the operating system that you want to repair, and then click Next.
  6. In the System Recovery Options dialog box, click Command Prompt.
  7. Type Bootrec /RebuildBcd, and then press ENTER.

Thanks. Forgot to mention i have done that as well.

 

Strange thing is that it says. "Windows installation =0" at the end of that session.

 

Btw. This method requires that your Bios recognize my SSD but mostly the Bios SATA information says that HDD Slot 1 is empty. Then you cannot perform any solutions.

 

I unplug power and wait 5 minutes and it then shows up again in Bios. Sounds a little like a power issue?

 

Thanks again.

That is a strange one, the only thing I can suggest now is the following I found for when it does show up related to the  "Windows installation =0";

 

If you saw;

 

Scanning all disks for Windows installations.

 

Please wait, since this may take a while...

 

Successfully scanned Windows installations.

Total identified Windows installations: 0

The operation completed successfully.

 

This result most likely means that Windows installation data in the BCD store exists but bootrec couldn't find any additional installations of Windows on your computer to add to the BCD. That's fine, you'll just need to take a few extra steps to rebuild the BCD.

 

  1. Since the BCD store exists and lists a Windows installation, you'll first have to "remove" it manually and then try to rebuild it again.

     

    At the prompt, execute the bcdedit command as shown and then press Enter:

    bcdedit /export c:\bcdbackup
    The bcdedit command is used here to export the BCD store as a file: bcdbackup. There's no need to specify a file extension.

     

    The command should return the following on screen:

    The operation completed successfully.
    meaning the BCD export worked as expected.

     

  2. At this point, you need to adjust several file attributes for the BCD store so you can manipulate it.

     

    At the prompt, execute the attrib command exactly like this:

    attrib c:\boot\bcd -h -r -s
    What you just did with the attrib command was remove the hidden, read-only, and system attributes from the file bcd. Those attributes restricted the actions you could take on the file. Now that they're gone, you can manipulate the file more freely - specifically, rename it.

     

  3. To rename the BCD store, execute the ren command as shown:
    ren c:\boot\bcd bcd.old
    Now that the BCD store is renamed, you should now be able to successfully rebuild it, as you tried to do in Step 3.

     

    Note: You could delete the BCD file entirely since you're about to create a new one. However, renaming the existing BCD accomplishes the same thing since it's now unavailable to Windows, plus provides you yet another layer of backup, in addition to the export you did in Step 5, if you decide to undo your actions.

     

  4. Try rebuilding the BCD again by executing the following, followed by Enter:
    bootrec /rebuildbcd
    which should produce this in the Command Prompt window:
    Scanning all disks for Windows installations.Please wait, since this may take a while...Successfully scanned Windows installations.Total identified Windows installations: 1[1]  C:\WindowsAdd installation to boot list? Yes<Y>/No<N>/All<A>:
    meaning that the BCD store rebuild is progressing as expected.

     

  5. At the Add installation to boot list? question, type Enter Y or Yes, followed by the Enter key.

     

    You should see this on screen:

    The operation completed successfully.
    meaning that the BCD rebuild is complete.

     

  6. Restart your computer.

     

    Assuming that an issue with the BCD store was the only problem which is still my current working assumption, Windows should start as expected. Hope this helps!

No to be honest I don't. I'm afraid if the above doesn't solve the problem then I am at a loss without actually being able to sit in front of the computer itself. Sorry.

I really apreciate you time in this. 

 

I have followed your walktrough and this time i had "windows installation = 1" and ok.

 

Now its just time to do a flight and see if it holds, Will report back  :rolleyes:

 

So far thanks

 

PS!

If the failure continues would it be advisory to unplug every HDD besides the SSD ? Maybe moving the SSD to another slot ?

Well 30 minutes inflight with the NGX from a saved flight i got a blue error screen with "kernel_data_inpage_error"

 

Then restart and still the BOOTMGR is missing.

 

 

How many percent should i leave for the SSD ? I have noticed that the ramaining GB changes allmost on every restart

Just a heads up,

 

Now just about 58 minutes into a flight with new cables AND a new CMOS CR2032 battery.

 

talking about fail anallyze :-)

Update,

 

I finished the flight EGLL-EKCH after changing CMOS CR2032 battery and cable

 

Normally i change battery every month due to some issues with ASUS boards but this was just a wild guess. Lets see if it works

It did not. New SSD or backup from a system image?

Hi again,

 

Is it normal to have some space not allocated on drive c?

 

I have 101mb .

 

Still boomgr during windows sessions and Prepar3D.  Could it be a virus ?

 

Thanks Michael

If a backup from a system image works then that would be my next step if I were doing things. This is how my disk looks which would suggest something is amiss alright. It might be worth trying the backup first to see if it works as I've found it won't always depending on the method used. When I learned this the hard way I started using Acronis backup which so far has been bulletproof. It alows you to make bootable disk with the software onboard to perform a clean backup in the worst of situations. I digress, failing the above it might be worth trying to extend the disk into that unallocated space.

Thanks ,

 

everything is going downhill here. The system freezes etc , 

 

How do i extend that none allocated if i need it ?

 

Thanks again

I feared it might. You're not having a good day, it truly sucks when things like this happen. In the Disk Management screen, just right-click on the partition that you want to resize and select “Extend Volume” from the menu. Fill in the amount of space in MB that you want to extend into. The extend partition feature only works with contiguous space but i seems from the above picture that that's what you have so you should be okay.

Right now i am looking at a very long image rebuild from two weeks ago. I have moved around the hdd drives because of P3D lately allthough not the C drive. This takes therefor much longer to rebuild the system.

Yes, it is normal to have 100mb "system reserved", i have it too.I have a z97-p and never had a crash in p3d (unless when i had cpu oc to 4.8 with insufficient voltage, which i resolved using 4.7 or when i tried some oc settings on ram and gpu).I would try a fresh OS install, i know it is boring but it could be faster than wondering the reason from the manywhich are possible.Make sure to install the newest chipset. Management engine and audio drivers from asus site.

Sounds more like a hardware issue to me. Failing controller or power supply on the SSD perhaps. Did you do a health check with this drive? btw. SSDs should not be filled up to more than 80%. And they do a lot more internally than the HDDs did, constantly trimming and cleaning the memory. Can you back it up, then connect it to another computer? Get the SMART values off the SSD, if it has them? Change to a HDD for the time being.? Use a different port and power supply cable?

 

Incidently, how are the temperatures in your PC case? If you constantly get crashes after a certain period of time, it might be something is overheating (a faulty circuit may not even need much heat to fail entirely).

Thanks everyone. My hdd was actually about 80-85 % full. The temperatur seems ok. The cpu on default is about 29c in Windows. I went to eventviewer and there was a case from yesterday about a controller ide port 0 problem.

 

 

 

Right now 5 hours had past and 40% has been rebuild but only on Drive C. This is going to take 30 hours or more.

 

Thanks Everyone

True but not what he asked. System reserved and unallocated space are two very different things. Have a look at the image on the end of page one.

I had something similar a while back.. it was due to bad OC.

This happened even without OC. I am still rebuilding .

 

It takes really long time. I am expecting 72-80 hours in total

 

There are actually alot of cases with issues with SSD as a OS HDD. Lots of people having this "loosing connection to SSD" out there.

 

Maybe it really is new hitech and controller problem afterall. Will see if my rebuild will work

 

On second hand anyone who have a SSD favorit for an Z87-Pro motherboard ? (240GB should do it)

 

There are also the new M2 ones ?
