    I mean this.

    Also, system restore and recovery console are not the same thing.

    Default Thanks Blade

    Thanks Blade,

    I will look at the link you provided and also try rebooting to last known good config. I can't do this right now as today is my wife's birthday and we're heading out to eat. I will get back on this again in a couple of hours and post what happens. I do appreciate your assistance.

    Default Can't restart Windows

    Hi Blade81,

    I do not have any good news.

    I cannot restart in NORMAL or SAFE MODE or to LAST KNOWN GOOD CONFIGURATION. RESULT = Same Blue screen

    If I restart with the F8 key, the select START NORMALLY, SAFE MODE or LAST GOOD CONFIG, and then select Microsoft Windows Recovery Mode, I come to a selection screen labeled Microsoft Windows XP Recovery Console which asks me "Which Windows installation would you like to log on to?"

    There is only one choice...
    1: C:\Windows

    Pressing #1 and then Enter I come to a black screen with a Dos Prompt...
    C:\WINDOWS>_

    Once there, I ran...
    1. chkdsk c: with no switch - RESULT= Volume appears good and was not checked
    2. chkdsk c: /p - RESULT = Chkdsk ran to 25% then slowly to about 50% the a bit faster to 75% and then quit and reported results. (The Drive is about 75% full)
    3 Then ran chkdsk c: /r - RESULT CHkdsk ran OK to about 50% then slowly to 75% and returned to 50% and again slowly to 75% and back to 50%. I then powered off.

    Still can not boot to any Windows XP mode except the Black Screen DOS Prompt when pressing F8 while restarting then selecting NORMAL, SAFE, or LAST KNOWN GOOD CONFIG, and then choosing Windows Recovery Console.

    Do you think I will ever be able to restart Windows XP again?
    Perhaps with...
    ...the ERUNT Registry Backup?
    ...the ComboFix Registry Backup?
    ...any other means?

    Or am I doomed to reformatting this hard drive and reinstalling everything?

    I look forward to your guidance and suggestions.
    TomZT

    Hi,

    We'll try to restore things back. First I'd like to know if you have a flash memory to transfer c:\ComboFix.txt file (if it's present) from infected system?

    This can be done from by entering recovery console (like you did earlier) and entering following commands (press enter after each one), f: drive is usb drive letter here (it may be different in your system):
    set allowallpaths = true
    set allowallremovablemedia = true
    copy c:\combofix.txt f:\combofix.txt

    Default Recovery

    Hi Blade,

    I will try your suggestion... But first I have a couple of questions...

    What method should I use to get to the Recovery Console...
    F8 when Booting, then SAFE MODE, Then Recovery Console?
    F8 when Booting, then NORMAL MODE, Then Recovery Console?
    or, F8 when Booting, then LAST GOOD CONFIG MODE, Then Recover Console?

    I have several mapped network drives on this computer but I'm not sure what drive letters have been assigned to them. Is there any way I can, from the Recovery Console, determine the correct letter for the Flash Drive?

    I await your reply.
    Tom

    When system reboots you should have two options to choose from (those will appear a couple of seconds):
    Microsoft Windows XP Recovery Console
    Windows XP Professional

    Choose recovery console. You could copy some dummy test file to your flash drive (create empty test.txt file with notepad for example) and then in recovery console, after entering those two set commands instructed in my previous post, use command dir <drive letter> e.g. dir f: and see what will list test.txt file.

    Default Recovery

    I created a test.txt file on another machine and saved it to a flash drive. Then plugged the flash drive into the infected machine.

    Then entered the Recovery Console...
    C:\WINDOWS>_

    The first command: set allowallpaths = true (this worked fine)

    The second command: set allowallremoveablemedia = true (this did not - bad parameter). After using the DOS command (HELP - /?) feature, I modified your parameter slightly, and tried: set allowremovablemedia = true (this seemed to work fine).

    The ONLY GOOD NEWS SO FAR is, after the above commands, I discovered that Combofix did create a ComboFix.txt file; however the file was actually located in C:\ComboFix\combofix.txt (361 bytes) rather than in the C:\ (root directory).

    So then I entered your third command (modified slightly):
    copy c:\combofix\combofix.txt f:\combofix.txt (this did not work - NO floppy or CD in drive).

    Trying to find the correct drive letter for the Flash Drive, I tried...
    dir f: - (this did not work - No floppy or CD in drive) Then...
    dir g: - dir h: - dir h: - etc. - on through: dir z: (this did not work - All reported invalid path or file)

    So the ComboFix.txt file is in there, I just need to find out how to get it out! Any more suggestions?

    Default More good news, I hope

    I remembered from my old DOS days the commands Print or LPrint.... Couldn't find any help on those commands but searching further in the DOS command help feature, I re-discovered that I could use the type command to display a text file on-screen. So I entered...

    type c:\combofix\combofix.txt

    Here (re-typed by hand) is the contents of the ComboFix.txt file...

    I sure hope this helps Blade!

    Hi Tom,

    Seems that ComboFix didn't get far there. Let's see if we can get your system bootable now.


    1. Restart your computer
    2. Enter to recovery console like earlier.
    3. At the C:\Windows prompt, type the following bolded text, and press Enter:

    cd erdnt\subs

    4. At the next prompt, type the following bolded text, and press Enter:

    batch erdnt.con

    5. The erunt backups will begin copying.
    6. At the next prompt, type the following bolded text, and press Enter:

    exit

    Windows will now begin loading. See if you're able to create a fresh DDS log now

    Default No Joy

    Hi Blade,

    I ran the ERUNT Registry Restore as described above...
    from c:\WINDOWS>_

    cd erdnt\subs
    batch erdnt.con
    (appeared to complete successfully - 9 files copied - returned to prompt)
    Then... exit

    Windows began loading and then displayed the same blue screen described in my previous posts.

    Tom
