Are there any version of MBytes that we can download an ISO image and burn to a CD that will have an autoboot sector on it for a badly infected PC?  We have a laptop that I suspect some sort of virus, running Windows 7, that seems to boot normally with the Windows logo and all at bootup,but then goes to just a black screen with a working mouse. NO toolbars, no background, nothing. When you try to do a system restore, same thing. CTRL-ALT-DEL also fails to do anything.  About the only option is to do a fresh install of Win 7, but if there is a bootable version of software to scan the machine that would certainly be beneficial.

 

Thanks.

Welcome to the forum, we can try this to see what's on the system: (I'm not aware of a MB bootable cd)

  • Please download Farbar Recovery Scan Tool and save it to a flash drive.


    Please make sure you click download buttons that look like this, not "sponsored ad links":

    Note: You need to run the version compatible with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

    Plug the flash drive into the infected PC.
  • If you are using Windows 8 consult How to use the Windows 8 System Recovery Environment Command Prompt to enter System Recovery Command prompt.

    If you are using Vista or Windows 7 enter System Recovery Options.

    To enter System Recovery Options from the Advanced Boot Options:
    • Restart the computer.
    • As soon as the BIOS is loaded begin tapping the F8 key until Advanced Boot Options appears.
    • Use the arrow keys to select the Repair your computer menu item.
    • Select US as the keyboard language settings, and then click Next.
    • Select the operating system you want to repair, and then click Next.
    • Select your user account an click Next.
    Note: In case you can not enter System Recovery Options by using F8 method, you can use Windows installation disc, or make a repair disc. Any Windows installation disc or a repair disc made on another computer can be used.

    To enter System Recovery Options by using Windows installation disc:
    • Insert the installation disc.
    • Restart your 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.
    • Click Repair your computer.
    • Select US as the keyboard language settings, and then click Next.
    • Select the operating system you want to repair, and then click Next.
    • Select your user account and click Next.
  • On the System Recovery Options menu you will get the following options:
      • Startup Repair
        System Restore
        Windows Complete PC Restore
        Windows Memory Diagnostic Tool
        Command Prompt


        Select Command Prompt

        Once in the Command Prompt:
    • In the command window type in notepad and press Enter.
    • The notepad opens. Under File menu select Open.
    • Select "Computer" and find your flash drive letter and close the notepad.
    • In the command window type e:\frst (for x64 bit version type e:\frst64) and press Enter
      Note: Replace letter e with the drive letter of your flash drive.
    • The tool will start to run.
    • When the tool opens click Yes to disclaimer.
    • Press Scan button.
    • It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

I am working on this today. I can download the version I need of this file and put on a flash drive, but how do I run it? I am unable to run anything as when the system boots, it's a solid black screen with mouse cursor only -- both in standard and in safe mode. 

 

Even trying system recovery ends up with the blank screen and mouse cursor after it loads the recovery files.

 

Thank you.

Do you have a W7 disk or can you make a repair disc??

Note: In case you can not enter System Recovery Options by using F8 method, you can use Windows installation disc, or make a repair disc. Any Windows installation disc or a repair disc made on another computer can be used.

EDIT:

It would be even better if you could create this disk
