Lets see the registry first . Try this please

In the command prompt that shows
X:\Sources

Type in bcdedit | find "osdevice" include the quotes .

Note   Note
the | is the key above Enter . Hold shift down and press the key with \ on it


Press the enter key after you input the command . It will tell you the drive letter of Windows . It might say its
os device partition=D:

ADDED

Note   Note
You should be using the steps below in Safe Mode with Command Prompt


Open Registry inside command prompt . Type in REGEDIT and press Enter if that doesn't work type C:\Windows\System32\Regedit.exe and Navigate to

HKEY_LOCAL_MACHINE
SOFTWARE
Microsoft
Windows NT
CurrentVersion
Winlogon

In the right side of the window locate "Shell" and right click on it. Click on Modify.

Note   Note
The default value data is Explorer.exe


If you see something else written in this window remove it and type in Explorer.exe (you can write down whatever else was written in the value data section - this is a path of the rogue execution file) - use this information to navigate to the rogue executable and remove it.

Restart the PC

It isn't recognizing it an I am getting the same error message. I did get the D for the partition. Did you want me to try the other way that you were talking about in bold or was that just for shawn77.

Ok if you got the command saying its D . Type this command then
CD D:\Windows\System32\Regedit.exe see if that will open up the registry .

That didn't work the response says "The system cannot find the path specified" I need to stop for tonight. Is it ok to stop at this point and try again tomorrow? I really appreciate all of the hard work you have put into helping me out.

Ok and you're welcome . Hopefully you're pressing the F8 to get to the command prompt and not the installation disc .

Hi Vistaking

Let me explain to you regarding ransomwares.Ransomware hooks entries in multiple locations.Winlogon and Run keys.Fixing both the keys using recovery console method will fail and user will just have a white screen because the ransomware is active.

Quote:
If the user can't get into save mode the programs you're mentioning is useless .
Wrong.How did user try the system restore or access MSCONFIG in his previous steps?

Safemode with command prompt gives us a command window.Flash drive can be accessed and any security tools can be used to scan our system without launching the explorer window.

Safemode with command prompt or FRST are best way to fix it.Launching registry in recovery console is time consuming.

6) Click “Ok” to close the “Internet Options” window.
Reboot

PattieO,

The Emsisoft Emergency Kit (Post #21 by shawn77) or HitmanPro.Kickstart are your best choices to access the computer, scan it for malware, and remove this infection.
HitmanPro.KickStart, in particular, targets the ransom-ware.

Can you access the Desktop?

If not, can you access Safe Mode with Networking? <<Per Post #22, looks as if you can. That is good!

Please confirm, and will do my best to guide you thru some simple instructions.
