Title: Problems with laptop
Post by: Hannu on September 21, 2013, 04:07:00 PM
Hi

I have HP Pavilion dv6000 laptop. It has Windows Vista home premium 32 bit OS. I got the laptop used, and have been cleaning and uninstalling programs I don't need.

I deleted recovery partition with HP tools (can't remember program name) to get more HDD space. After that I uninstalled previous antivirus (F-secure) and installed Microsoft secyurity essentials and installed Windows Vista Service pack 2. There was also some malware (can't remember what) MSE tried tried to remove. MSE asked to reboot windows to fully remove malware, and I think this messed windows boot somehow. I also run Norton unistall tool to remove previous Norton software. I then booted, and now I can't get boot into windows. I get STOP 0x0000007B BSOD if remember correctly. I can't do startup repair because it gives me 0xc00000f error too. Also, I can't even boot into safe mode! I am at a loss and don't know what to do next.

I don't have Vista repair disc, but I do have full image backup which I made with Macrium reflect earlier this week.
Now I am running Hard disk self test (through bios). I'll post results later.

What malware did MSE find ? 

This sounds like the MBR is broken

Are you able to get to safe mode menu ?
From the repair menu can you access command prompt ?

Malware was related to Java and Internet explorer cache, I can't remember and I don't have picture from it. I can get into safe mode menu, but it just reboots when trying to enter safe mode. Windows startup repair does not work.
How can be MBR be repaired?

On the safe mode menu is the option Command Prompt
Can you select that ?

Also do you have a spare USB

Hard drive test did not found nothing. See pic:
Yes, I have spare USB.
It has the option safe mode and command prompt. Do you mean that?

update:
I can select the safe mode command prompt, but it just loads for some time and then reboots  :(

That's the one

Download to a USB
Farbar Recovery Scan Tool (http://www.bleepingcomputer.com/download/farbar-recovery-scan-tool/) 

Insert the USB and boot to the safe mode menu
Select Command prompt

At the command prompt type the following  :
 
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.exe 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. 
(https://dl.dropbox.com/u/73555776/FRST%20Start%20scan.gif)
Press Scan button. 
It will make a log (FRST.txt) on the flash drive. Please copy and paste it to your reply.

Could you run a fresh FRST scan please

Hannu, macrium reflect boot disk/restore disk has a "fix boot problems" utility that you might try if what you're doing now doesn't work. :)
Just thought I'd pass this along.

OK we are going to have to edit the BCD to get it to boot now

Unfortunately we will need a Vista recovery console on USB or CD do you have access to either a running vista system or a Vista CD

I borrowed a Vista recovery cd from friend and did startup repair, which could not make repairs (see pics)
But at least I can now access recovery console:

Post by: essexboy on September 22, 2013, 12:25:09 PM
OK from the CD command prompt :

Type BOOTREC /FIXMBR, and then press ENTER. 

Type BOOTREC /FIXBOOT, and then press ENTER. 

Type BOOTREC /REBUILDBCD, and then press ENTER. 

Now retry a normal boot

did a normal boot, and got 0x0000007B BSOD.
what concerns me, is this: total identified windows intallations: 0 ?? (see pic)

It looks as though you will need to reinstall I am afraid as the MFT may well be corrupted

You can use the Reatogo desktop to backup any data you need

Hi, yes it is.
Is macrium able to restore the image you made and start over again?

So you are back up and running now ?

Was the image prior to the bad boys that I removed ?

Yes, Windows Vista seems to be working fine now.
I don't know yet if there is malware on this image, but made a scan with Hitman pro and it found nothing. My guess is that malware got into computer after I turned off UAC. I don't know.

There seems to be remnants of F-secure, Norton 360 and its backup files (don't know what to do with them) and Mcafee security tool. I have to get rid of those first and then make new image.

Right now I'm so fed up with that laptop that I won't be touching it for a few days!

Hello again!

Laptop (and windows) is working fine now, installed Service pack 2 and all available updates from windows update.

I ran ESET online scan one day and it found something. Also ran OTL scan today and i would be nice if someone could check if there is something of interest in the logs. Thanks.

Looks good.  The ESET detections are signature files for Spybot S&D and are of no import
