If the welcome logo you're talking about is the Microsoft logo on a black background, then we have the same experience.

One possibility may be:

When you used Combofix, you might have deleted a file necessary for start up. This may be the reason why it is advised here at BC to use Combofix with care and with supervision of someone knowledgeable enough about using it.

*This is based on my personal experience combined with some of the things that I learned about computers.

It is still best for this to be confirmed by more knowledgeable members.

Unfortunately you have discovered why running Combofix on your own is not recommended.

Please note the message text in blue
at the top of the Am I infected?
What do I do?
forum.

ComboFix It is an extremely powerful tool which should only be used when
instructed to do so by someone who has been properly trained in the use of the program.
ComboFix is intended by its creator to be "used under the guidance
and supervision of an expert
", NOT for private use.
Please read
Combofix's
Disclaimer
.. Using this tool incorrectly could
lead to disastrous problems with your operating system such as preventing
it from ever starting again.


(Papakid @ Mar 1 2009, 09:30 PM)
Running ComboFix by yourself is like performing open heart surgery on yourself--the
scalpel and other surgical tools that is ComboFix is meant to be wielded by a highly
trained surgeon only in emergencies or dire circumstances. When the surgeon is
thru s/he leaves the room. So combofix should be removed from a system once it
has accomplished its job, unlike an AV that is there to protect you from future infections.

. . . CF does make some alterations to your system if you run it. Even if you
had no malware removed and run the uninstall command, some things may be
different now on your system. I can tell you that one thing is that all
your restore points will be flushed out and a new one created. There is
a good reason to do that when you have a severe infection--but if you
aren't infected you might need those restore points.

Read and abide by the disclaimer people. It's there for a reason.
Stick to running and protecting yourself with a good AV and firewall
and an anti-malware scanner or two. If you feel you need a second opinion,
try running online scans. If you feel you might need surgery, come here to
BC and ask for help--that is what we're here for.

We will have to create a small 'fix CD' to solve this problem.
Please download RC.ISO and save it somewhere you can find it.
Also download MagicISO and install it.

Start MagicISO. You should see a window informing you about the full version of MagicISO.
In the bottom right select Try It! and the program will open.
Click on File and then on Open and navigate to the RC.ISO file you downloaded. Select it, and click Open.

First, we'll need to add a clean version of userinit.exe to the current RC.ISO
  • In the upper right pane, double click on the i386 folder.
  • Right click in the upper right pane and select Add Files...
  • Navigate to C:\Windows\System32 and select userinit.exe
  • Then click Open to add userinit.exe to the CD image.
  • Click File and select Save As...
  • Name the file RCplus and save it somewhere you can find it.
Next, we'll need to burn the newly created image to a disk that we can use to fix the problem.
  • Put a blank CD-R disk in your CD burner and close the tray. If an AutoPlay window opens, close it.
  • Click on Tools and select Burn CD/DVD with ISO.... A window will appear.
  • Click on the little folder to the right of CD/DVD Image File then navigate to the newly created RCplus.iso Image file and click Open.
  • In the CD/DVD Writing Speed drop-down menu choose the 8X setting.
  • Under Format make sure that Mode 1 is selected.
  • And finally, click on the Burn it! button to burn RCplus.iso to disk.
Once the disk is burned, put it in the machine you want to fix and restart it.
Boot to the CD just as you would with a Windows XP disk.
At the Welcome to Setup screen, press R to enter the Recovery Console.
Choose the installation to be repaired by number (usually 1) and press Enter.
When you are asked for the Administrator password, enter the password or leave it blank (default) and press Enter.

At the C:\Windows> prompt, type the following commands pressing Enter after each one. Note: Watch the spaces.

D:
cd i386
copy userinit.exe c:\windows\system32
exit

After putting in the third command, you should receive the message 1 file copied which will indicate that the operation succeeded.
Now take out the CD and reboot your computer to normal mode. Try to log in and it should let you back in.

You may consider using another computer to do all the preparations needed. After you have created the disk, that's the time you could use it to fix your computer. :thumbsup:

Sorry, I misread your post
I thought it only went that far and restarted again in a continuous loop. I didn't see where it just hangs and stops

nitty,

To be honest, there is very little help that can be offered.
We have no information to work with other than

I used Combofix to repair one problem on my Pc and I done it, but now my Pc don't want to start up
It's going until welcome logo and cannot start up anymore


There could be various reasons for this, the least likely is Combofix

One possibility may be:

When you used Combofix, you might have deleted a file necessary for start up.


Possible ?, yes ... Combofix is very powerful.
Unlikely ? .... Yes, Combofix has a lot ( and I do mean a lot ) of safety measures built in to prevent this sort of thing happening.

It has been mentioned that Combofix should be "used under the guidance and supervision of an expert",
There are good reasons for this.

Questions for you ...
1) Do you have an install disc for your machine ?
2) Did you install the Recovery Console when Combofix requested that you do so ?
3) Did you run any other cleaning/removal tools before you rebooted your machine ?

No, but it may help in restoring your machine.

What about the other two questions ?

1) Do you have an install disc for your machine ?
3) Did you run any other cleaning/removal tools before you rebooted your machine ?

Recovery options should be available before the welcome screen.
It is often F11 to access the Recovery partition functions.

Have a look on the companies website if you don't have any documents.

Given that we have no info to go on, the best option is to do a "Repair" install.
