Dear Britec Forum,
I receive this error:
File: \Boot\BCD
Status: 0xc0000098
Info: The Windows Boot Configuration Data file does not contain a valid OS entry
upon start up on my:
HP Pavilion dv4 Notebook PC
Bios ver. F.17
CPU: AMD Turion II Dual-Core mobile M520
OS: Windows 7
I first received a, "BOOTMGR is missing," but I fixed it after copying the BOOTMGR file off my windows 7 install disc. But now I'm receiving this message. I think I may have messed up some of my files during the repair process of the BOOTMGR when putting commands into the command prompt from various troubleshooting guides scattered on the web.
If anyone can help me with this problem I would greatly appreciate it.
Thank you

I've done what you suggested and it says it can't repair the problem because there is "NoOSInstalled" under signature 07 of the problem details

Hi there xyy
This Is a Common Problem that happend in vista using a bit torrant download this iso file
Here and the burn the Iso to CD
use this tool set to fix the problem click on repair start up problems
and then continue though the setup once you have completed the repair this should sort out the problem
use a iso burner to burn the iso and a bit torrant to download the torrant it is a good bit of kit and also has recovery tools on it as well
if you need any more help let me know
Kind Regards

Hi there,
The reason that you are getting this error is because the Windows Boot Manager (Bootmgr) entry is not present in the Boot Configuration Data (BCD) store or that the Boot\BCD file on the active partition is damaged or missing.
That is why you are now getting the "NoOSInstalled under signature 07" message after trying the Start-up Repair option as suggested by tf76.
To rectify your problem you can rebuild the BCD store using the Bootrec.exe tool in the Windows Recovery Environment.
Do this by following these steps:
1. Re-start the computer, pressing the F8 key at the same time (Windows Recovery Console is part of Win 7 installation, no need to use your installation DVD).
2. Select "Repair Your Computer" from the screen that appears. Windows loads the necessary files.Click NEXT
3. Select a language and a keyboard on the screen that appears and then click Next.(Windows will now search for installed operating systems, if you only have one, Win 7, it will be selected otherwise Click the operating system that you want to repair).Click NEXT.
4. In the System Recovery Options dialog box, click Command Prompt.
5. Type Bootrec /RebuildBcd and ENTER.
6. If Bootrec.exe runs successfully, you will see the installation path of the Windows directory. To add the entry to the BCD store, type Yes. A confirmation message appears that indicates the entry was added successfully.
7. If Bootrec.exe does not find any missing Windows installations, you must remove the BCD store, and then you must re-create it.Do this by typing the following commands.
Bcdedit /export C:\BCD_Backup - press ENTER
ren c:\boot\bcd bcd.old - ENTER
Bootrec /rebuildbcd - ENTER
8. Restart the computer and you should be good to go.
Cheers HTH,

So I've done everything suggested so far but so far I'm still getting the same problem. The start up recovery can't repair the problem w/ the same "NoOSInstalled" problem. The command prompt method still isn't detecting any previous installations despite the fact that I've tried rebuilding the BCD store. When I put in the command ren c:\boot\bcd bcd.old it says, "A duplicate file name exists, or the file cannot be found."
I was wondering if any of the tools in the Microsoft Diagnostics and Recovery Toolset (MSDaRT) option could help me fix my problem? I don't know how to use the tools but there's a lot of different options that sound like they can help fix my problem.
Thanks

Hi There,
Run through the same procedure as before and after using the:
ren c:\boot\bcd bcd.old - ENTER command, if you get the same result, (you probably will do)
then type this at the prompt del c:\boot\ bcd.old - ENTER and then do the:
ren c:\boot\bcd bcd.old - ENTER command again. You should be OK now. Enter YES if asked.
Finish off with the Bootrec /rebuildbcd - ENTER command and then restart.
Cheers,HTH,

Alright did what you asked but it's still not working :( Still not detecting any installations. I can't help but feel this should be an easy problem to fix but my computer just does not want to cooperate  . Would anyone suggest that I just reinstall Windows? It would be tricky because it is a laptop and there are 5 different partitions on the HDD made by the manufacturer. So I'm going to keep trying everything suggested again and see if I get lucky. I'll try anything suggested after this post. Thanks! |

Hi there just been doing some research on the problem and it seems that your windows folder could quite possaible have been moved or remaned from drive C:\
using the disk you have made run the disk enter the microsoft dianosic tools and check to see if you have the windows folder in local disk c:\ or operating system as it may appear
to do this or check this go to explorer this will open up C:\ and also you will see all of your documents and settings and any other files you have on your hard drive.
Thanks for the feedback also what was mention was that the user may have a virus that will thow up this message if it is blocking the boot files check it out on system sweeper it explans what it dose it checks for viruses and delets any that it finds.
also when in explorer check in a folder called boot it is a folder it holds all your boot records make sure there is a item in each folder and if there is a folder without an item it it there is your problem.
also others and microsoft have mentioned that it is to do with missing drivers
there is a option at the very beginning of the disk to load drivers if your operating system is missing do this to get the drivers it needs
click download drivers.
also on the disk there is a tool cooled crash analizer check that and it will tell you more information why the system will not load
give any finding you get I will continue to support you in this matter untill it is resolved and also resurch the problem deeper
hope this helps speak soon
Bradley

Okay I'm looking at the C:\ folder and not exactly sure what I'm supposed to be looking for so I'm uploading screenshots of the contents inside the folder http://www.flickr.com/photos/23530613@N07/On the systems sweeper my OS isn't showing up but when I go to browse for my Windows folder on the Boot X drive it says I have an "Invalid Windows folder." So that's preventing me from running that test. As for loading the drivers I can't find the setup file to install the drivers. It's asking me to find it on the computer itself and not through a download. And finally, the crash analyzer wizard is completely foreign to me. You're going to have to give me a tutorial on using the wizard. I'm not exactly sure what to do with the symbol files and where to place the crash dump file etc. Thank you soooo much for your continued support! |

So I looked at the program's instructions and really don't quite understand how to make it work on my laptop. Can I boot the program from a flash drive on startup? Or do I use the recovery tool's explorer to open up the BlueScreenView program?

Bluescreen view is a portable program. So download it, put it onto a USB, boot from your live CD, put in your USB and execute it through an explorer type program.

Blue screen view can not work portable with this program you can not use it to view dump files in a pre installed enviroment because there is no way to run exe files.
when I looked at the files on C:\ in explorer there was no windows folder there this is your problem.
you should see windows and system volume information both are missing from it this is why windows can not start.
Now we no the problem we can help you need to do a reinstallation of windows 7 do you still have the disk?

I have an installation disc but the version of windows 7 on the disc isn't the same as the one installed on the laptop. The laptop has win 7 home and I have an installation disc for win 7 professional, and I've already used the key for win 7 pro for my desktop. Any suggestions?
