I have an install disk.

 

Good news, here is a script for fixing the MBR and writing a new boot sector.

 

See how it goes. If we have no luck I will post some instructions for a way to access your files before you re-install.

 

Now

 

Open notepad.

Please copy the contents of the code box below.

To do this highlight the contents of the box and right click on it. Paste this into the open notepad.

Save it on the flashdrive as fixlist.txt
 

cmd: bootrec /FixMbr
cmd: bootrec /fixBoot

This script is specifically written for the infection on this person's computer. It should NOT to be used on another machine. It may cause serious damage even to the point of rendering the computer unusable.

Please enter System Recovery Options, as we've done previously.
Run FRST64 and press the Fix button just once and wait.
The tool will make a log on the flashdrive (Fixlog.txt) please post it to your reply.

Time to see if we can use a DVD/CD to back up your data. :)

 

This might be a way for you to access the hard drive to backup your data.

These instructions come courtesy of phillpower2 from our technical section.

===================
***Required Hardware***
CD Burner (CDRW) Drive,
Blank CD,
Extra Storage Device (USB Flash Drive, External Hard Drive)

===================
 
1. Save these files to your Desktop/Burn Your Live CD:

  • Download Latest Puppy Linux ISO (i.e.: lupu-528.iso)
    Download BurnCDCC ISO Burning Software
     
    There are instructions on how to boot from flash drive with puppy here
     
  • Open BurnCDCC with Windows Explorer
  • Extract All files to a location you can remember
  • Double Click 1%20BurnCDCC%20Icon.PNGBurnCDCC
  • Click Browse 2%20BurnCDCC%20Browse%20Button.PNG and navigate to the Puppy Linux ISO file you just downloaded
  • Open/Double Click that file
    IMPORTANT: Adjust the speed bar to CD: 4x DVD: 1x
  • Click Start 3%20BurnCDCC%20Start%20Button.PNG
  • Your CD Burner Tray will open automatically
  • Insert a blank CD and close the tray
  • Click OK

Puppy Linux Live CD will now be created
2. Set your boot priority in the BIOS to CD-ROM first, Hard Drive Second


  •  
  • Start the computer/press the power button
  • Immediately start tapping the appropriate key to enter the BIOS, aka "Setup"
    (Usually shown during the "Dell" screen, or "Gateway" Screen)
  • Once in the BIOS, under Advanced BIOS Options change boot priority to:
    CD-ROM 1st, Hard Drive 2nd
  • Open your ROM drive and insert the disk
  • Press F10 to save and exit
  • Agree with "Y" to continue
  • Your computer will restart and boot from the Puppy Linux Live CD

3.  Recover Your Data

  • Once Puppy Linux has loaded, it is actually running in your computer's Memory (RAM).  You will see a fully functioning Graphical User Interface similar to what you normally call "your computer".  Internet access may or may not be available depending on your machine, so it is recommended you print these instructions before beginning.  Also, double clicking is not needed in Puppy.  To expand, or open folders/icons, just click once.  Puppy is very light on resources, so you will quickly notice it is much speedier than you are used to.  This is normal.  Ready?  Let's get started.
     
    3a. Mount Drives
  • Click the Mount Icon located at the top left of your desktop. 5%20Puppy%20Linux%20Mount%20Icon.PNG
  • A Window will open.  By default, the "drive" tab will be forward/highlighted.  Click on Mount for your hard drive.
  • Assuming you only have one hard drive and/or partition, there may be only one selection to mount.
  • USB Flash Drives usually automatically mount upon boot, but click the "usbdrv" tab and make sure it is mounted.
  • If using an external hard drive for the data recovery, do this under the "drive" tab.  Mount it now.

3b. Transfer Files.

  • At the bottom left of your desktop a list of all hard drives/partitions, USB Drives, and Optical Drives are listed with a familiar looking hard drive icon.
  • Open your old hard drive i.e. sda1
  • Next, open your USB Flash Drive or External Drive. i.e. sdc or sdb1
  • If you open the wrong drive, simply X out at the top right corner of the window that opens. (Just like in Windows)
  • From your old hard drive, drag and drop whatever files/folders you wish to transfer to your USB Drive's Window.

For The Novice:  The common path to your pictures, music, video, and documents folders is: Documents and Settings >> All Users (or each idividual name of each user. CHECK All Names!) >> Documents >> You will now see My Music, My Pictures, and My Videos.
 
Remember to only click once!  No double clicking!  Once you drag and drop your first folder, you will notice a small menu will appear giving you the option to move or copy.  Choose COPY each time you drag and drop.

If you're doing this to recover from a virus or malware infection, (or even if you're not), DO NOT copy executable files (.exe, .scr. etc...) if any of these files are infected you could be copying the corruption over to any new device/computer. just copy documents, pictures, music, or videos.
 
YOU ARE DONE!!!  Simply click Menu >> Mouse Over Shutdown >> Reboot/Turn Off Computer.  Be sure to plug your USB Drive into another working windows machine to verify all data is there and transferred without corruption. Congratulations!

Free and user friendly back up software that phillpower2, the technical consultant, often suggests and that has proved positive with members is Macrium Reflect

Tell me how you get on.  :)
