Help to Bad_System_Config_Info

[Seb0099]

Hey

Story: For a week ago I wanted to started my pc up in the morning. When the computer boot was starting on the Windows sign, there came a BlueScreenOfDeath.

This one: http://imgur.com/eTXZPEL

That day I searched all over the internet and finally I found this site. One guy have had the same problem and he wrote that he wrote two commands in the Commandprompt (CMD).

The 2 commands:
bcdedit /deletevalue {default} numproc
bcdedit /deletevalue {default} truncatememory

I wrote thoose commands in CMD and restarted the computer without a single BSOD. I was really happy, until yesterday where it happend again...
I wrote the same codes again and i helped, but do i really have to do that every time, it happens?

After the restart:
Avast - Turned off
MalwareBytes - Turned off
Windows defender - Turned off
Windows update - 5 to 20 updates

Is thosse things happening because windows made a restore?

Questions:
Why is there a problem in my registry?
How can I fix the correupted files, values, keys and so on.

Spec: Windows 7 64 Bit

Hope you guys can help me fix this problem, so it don't happen again.

- Sebastian

The 2 commands you use to logon to Windows, are commands to delete invalid bootloader values that prevent Windows 7 from booting and they are probably put there by a virus since your security programs get turned off, and that is a good indication (as well as corrupted files, values and keys) that your system is probably infected. So scan with your security programs to remove the virus and when that's done, install EasyBCD to remove bad BCDEdit (bootloader) entries and renew it with the correct Windows 7 entry. Use EasyBCD as follows:

In EasyBCD\click "Edit Boot Menu"\select Microsoft Windows 7\Click Delete\Click Save Settings\Exit EasyBCD and again open it... Go to Add New Entry\In Type; Select Windows 7\Select Drive C:\and Click on Add New Entry\click Save Settings.

You can instead of using EasyBCD, edit the bootloader typing the Entries given in the answers.microsoft.com forum thread but if they are the same you are using, the results may remain the same... or maybe they can be deffinite if you remove the virus before correcting the bootloader. So removing the cause is probably the most important part of the solution.

Hey Chicano

I recently runned malware bytes pro + avast full scan and nothing came up, but I will do it again now.

I don't think I have a windows CD because my laptop came with windows pre-installed.

Can I use BCDedit tool and still don't use a Windows CD?

 

[Chicano]

Did you perform quick or full scanns? Full scanns detect many more results than quick scanns. Also if your security programs were turned off, they could be compromised so try reinstalling them before scanning and also do Online virus Scanns and a Antirootkit scan with AVG Antirootkit

BCDEdit is the Windows Bootloader, EasyBCD is a Tool to edit BCDEdit... but you don't need a Windows CD to edit BCDEdit or to use EasyBCD to edit BCDEdit.

 

[Seb0099]

I did full scans and I'm beginging one now again.

I'm gonna try the BCDedit thing now.

 

[Seb0099]

I just did the BCDEdit thing and what now? shall I then just run some scans and it should be over?

 

[Seb0099]

Kaspersky: No infections
Housecall trend micro: No infections
Malware Bytes PRO: No infections

So I don't think it's a virus.

I did the BCDEdit thing.

 

[Chicano]

Do you mean you used EasyBCD to edit BCDEdit, and the boot problem is still in effect?. If that's so, something is changing the BCDEdit boot parameters... Try repairing the bootloader with the Windows Setup disk in the Repair options.

I used EasyBCD 2.2 to edit BCDEdit.

I don't know if it worked or not, because I only have gotten "bad_system_config_info" 2 times, with weeks apart.

I just wanna know if it's gone and dosen't come back again. How do i check the parameters my self?

I'm going to sleep now (denmark), so I will see it tomorwow.

If you are not getting the bad_system_config and don't have to type:
The 2 commands:
bcdedit /deletevalue {default} numproc
bcdedit /deletevalue {default} truncatememory
Then it's probably gone but there is no way to know for sure... you'll have to wait and see.

Checking the bootloader parameters is not easy, you can correct the bootloader (BCDEdit) parameters with EasyBCD and it should make the necessary corrections... It's as simple as using the program to delete BCDEdit and to rebuild it fresh and correct. I gave you those instructions before.

In EasyBCD\click "Edit Boot Menu"\select Microsoft Windows 7\Click Delete\Click Save Settings\Exit EasyBCD and again open it... Go to Add New Entry\In Type; Select Windows 7\Select Drive C:\and Click on Add New Entry\click Save Settings.

OK, to check the BCDEdit parameters.
From EasyBCD, click on Useful Utilities > Easy BCD Power Console > type BCDEdit the bootloader will show in the Command Prompt window... If the values are still there: (numproc and truncatememory). And delete them the same as you have been doing with:
Type: bcdedit /deletevalue {default} numproc
Type: bcdedit /deletevalue {default} truncatememory

Or through the EasyBCD program:
Delete the BCDEdit settings with the options on Edit Boot Menu > Select Windows 7 > click Delete > click Save Settings and next from Add New Entry > Select Windows 7 and Drive C and click on Add Entry... Next from Edit Boot Menu confirm that Windows 7 has been added and click Save Settings... This will create a fresh BCDEdit with default parameters.
