Problems with reboot after using Windows Defender Offline

[JudyinHawaii]

After being notified the Alureon Trojan was on my computer I followed the suggestion to use Windows Defender Ofline to remove the trojan. Once completed, and having cleaned the trojan, the computer would not reboot. It now says no BOOTMGR and just continues to reboot itself and goes back to NO BOOTMGR error. I cannot even get to a login screen or any other screen. I am typing this on a laptop as
my desktop cannot even be used now. The infected computer is a Dell Studio XPS using Windows 7 64bit.

JudyinHawaii,

Do you have a Windows 7 installation CD/DVD?

If not, is the computer running Windows 7 Home Premium, Professional, or Ultimate?

 

[JudyinHawaii]

No CD- windows 7 home professional

JudyinHawaii,

If none of the above works, we'll approach the issue in a different way.

There are other options.

Oay - CD is burned - what's next?

 

[cottonball]

Need to know what you have done so far.

Did you follow any of the instructions above, and they failed, or, are you starting with the system as it was?

Thanks!

Judy you could try this

Boot using a Recovery CD or Windows 7 Installation DVD to the Recovery Environment
At the System Recovery Options menu choose Command Prompt
At the command prompt type in the command:
bootrec /fixmbr
Press Enter to replace the MBR and then restart your computer.

 

[cottonball]

Isn't that command covered here:
http://www.sevenforums.com/tutorials/104341-bootmgr-missing-fix.html

Normally, I try to find out the source of the problem with special tools, and then take the appropriate action.

We have no clue what WDO damaged, if anything...

 

[JudyinHawaii]

Cottonball, you asked me to reply once I burned the CD - I have not done anything else.

I can't boot to anything except the Cd/DVD drive or a thumb drive in the USB. I can't get to a system repair option as The only thing that presents itself on the screen is BOOTMGR missing - Hit CTRL ALT DELETE to restart. When I hit CTRL ALT DELETE, it tries, but simply goes back to BOOTMGR missing..

 

[DocBrown]

When you hit CTRL ALT DELETE to restart, keep taping the F11 key to see if you get a boot menu option, so you can choose the DVD.

 

[VistaKing]

You have a dell so while the PC is booting up tab on the F12 key then choose optical disc or drive .

 

[JudyinHawaii]

OK Cottonball, CD loaded, now I am at "Install Windows" or "Repair Computer" on the Windows 7 screen - repair computer??

 

[VistaKing]

Click on Repair your computer
Select Windows 7 and the click on Next.

:ar: On the System Recovery Options menu you will get the following options:

Thanks, JudyinHawaii,

Did not want to re-invent the wheel, if you had already tried something else, etc.


Let's press on...

Please plug a USB pendrive into a clean computer.
Go to Start > Computer
Double-click Computer, and select the pendrive.
Right-click and select: Format
Press Start on the Format prompt.
Remove the pendrive when done.

Download Farbar Recovery Scan Tool:
Farbar Recovery Scan Tool Download
Select the 64-bit download.
Save the program to the >> USB pendrive.


Step 1.
Please go to the infected computer.
Plug in the pendrive which has FRST.

To enter System Recovery Options using the Windows Seven Recovery Environment Disc:
¦Insert the disc created into the CD drive.
¦Restart the computer.
¦If prompted, press any key to start Windows from the installation disc.

(If your computer is not configured to start from a CD or DVD, check your BIOS settings to do so.)

Step 2.
¦Select Language settings, etc., and then click: Next
¦Select the Operating System you want to repair, and then click: Next
¦At the next prompt, click Repair your computer

Step 3.
On the System Recovery Options menu you get the several options...

Select: Command Prompt
¦In the Command Prompt window, at the blinking cursor type notepad and press: Enter
¦In Notepad, under the File menu select: Open
¦Double-click the Computer icon on the left.
¦Find the pendrive letter, remember what letter it is, click on it, and press: Open
¦Close out of Notepad.

Step 4.
Back to the Command Prompt window...
¦Type g:\frst64.exe, and press: Enter
Note: Replace the drive letter g with the drive letter of your pendrive!

Step 5.
¦FRST64 starts and prepares to run. Follow the prompts.
¦Click Yes to the Disclaimer.

Press the Scan button.

The scan runs, and, the program saves the FRST.txt, on the pendrive.

Step 6.
When done, click the Command Prompt window, type exit, and press: Enter

Remove the USB pendrive.

Back at the System Recovery Options, press: Shutdown

Please provide the FRST.txt in your reply. It is located in the pendrive.

Based on the results, we'll pursue whatever action is appropriate.
