• Error - NTLDR is missing from the Windows XP computer.

  Original title: difficulty ntldr missing.

  I don't have xp recovery disk. I get lack ntldr message at startup. How can I fix wihout disc?

  Since the MS Answers forum does not prompt for any information system when a new question is asked, we know absolutely nothing about your system.  What makes which gives good ideas for extremely difficult solution.

  Provide information on your system, the better you can:

  What is your system brand and model?

  What is your Version of XP and the Service Pack?

  Your system have IDE or SATA disks?

  Describe your current antivirus and software anti malware situation: McAfee, Symantec, Norton, Spybot, AVG, Avira!, MSE, Panda, Trend Micro, CA, Defender, ZoneAlarm, PC Tools, Comodo, etc..

  The question was preceded by a loss of power, aborted reboot or abnormal termination?  (this includes the plug pulling, buttons power, remove the battery, etc.)

  The afflicted system has a working CD/DVD (internal or external) drive?

  If the system works, what do you think might have changed since the last time it did not work properly?

  You can create a bootable CD from the Console of the Recovery XP (no XP media required) and start the XP Recovery Console.

  The chances are pretty good that there is a copy of the NTLDR file on your system to another location, so you can replace the missing file.

  The file is supposed to be like c:\ntldr c:\ root folder (note there is no file for the ntldr file extension) but of course your seems to have developed missing.

  If your system is preinstalled with XP there is probably a folder c:\i386 on your system and that there should be a copy of the file in folder c:\i386 NTLDR.

  If you have installed Service Pack 3 download Internet via the World Wide Web Wide, there will be a copy of the NTLDR file in this folder:

  c:\Windows\ServicepackFiles\i386

  Once you get started the recovery console and you ran chkdsk/r, I would see if these commands will work for you to replace the missing file:

  copy c:\i386\ntldr c:\

  or

  copy c:\windows\servicepackfiles\i386\ntldr c:\

  Here's how to make a CD of bootable XP Recovery Console and I would run the chkdsk /r FIRST to make sure that your file system is not damaged.

  Boot into the Recovery Console Windows using an XP bootable installation CD.

  If you have no XP bootable media (or aren't sure you have) create a bootable XP Recovery CD of Console and do not forget.

  This is not the same as recovery disks that might have come with the acquisition of the system store.

  You can make a bootable Recovery Console CD by downloading an ISO file and burn it to a CD.

  The ISO bootable image file you need to download is called:

  xp_rec_con. ISO

  Download the ISO from here:

  http://www.mediafire.com/?ueyyzfymmig

  Use a new CD and this simple and free program to burn your ISO file and create your bootable CD:

  http://www.ImgBurn.com/

  When you install ImgBurn, DO NOT install the Ask toolbar.

  Here are some instructions for ImgBurn:

  http://Forum.ImgBurn.com/index.php?showtopic=61

  It would be a good idea to test your bootable CD on a computer running.

  You may need to adjust the computer BIOS settings to use the CD-ROM drive as the first device to boot instead of the hard drive.  These adjustments are made before Windows tries to load.  If you miss it, you will need to restart the system again.

  When you start on the CD, follow the instructions:

  Press any key to boot from CD...

  Installing Windows... going to pronounce.

  Press 'R' to enter the Recovery Console.

  Select the installation that you want to access (usually 1: C:\WINDOWS)

  You may be asked to enter the password (usually empty).

  You should be in the folder C:\WINDOWS.  It's the same as the

  C:\Windows folder that you see in Solution Explorer.

  The Recovery Console allows base as file commands: copy, rename, replace, delete, chkdsk, fixboot, fixmbr, cd, etc.

  For a list of the commands in the Recovery Console, type help at the prompt of commands or read on here XP Recovery Console:

  http://www.Microsoft.com/resources/documentation/Windows/XP/all/proddocs/en-us/recovery_console_cmds.mspx?mfr=true

  A good idea before you start things must first verify the integrity of your file system by using the chkdsk command.

  In the command prompt window, run the chkdsk command on the drive where Windows is installed to try to fix any problems on the afflicted player.

  Running chkdsk is fine, even if he finds no problem.  It won't hurt anything to run it.

  Assuming your boot drive is C, run the following command:

  CHKDSK C: /r

  Let chkdsk finish to correct the problems, he could find.

  It may take a long time for chkdsk complete or they seem to be "stuck".  Be patient.  If the HARD drive led blinks always, chkdsk is something.  Keep an eye on the amount of the percentage to be sure that it is still making progress.  It may even seem to go back sometime.

  You must run chkdsk/r again until it finds no error to correct.

• Where to go to set the channel missing from the Windows Media Center Program Guide

• Presentation settings is missing from the Windows Mobility Center

  Satellite L 300 with Vista Home Basic

  Recently installed everything, but have run windows update etc. Since then.

  Presentation settings does not appear in the Windows Mobility Center, and I can not find presentationsettings.exe anywhere on the computer.

  Have tried downloading VAP but no difference. Toshiba Assist has nothing to help me, I think.

  I tried looking for drivers and utilities for the L300 and sees nothing to help me - no presentation or power related only downloads.

  How can I get the presentation settings? The main problem I have is not to want the screen empties when you watch a DVD or streaming video. Even if you put windows power settings to never turn off the screen, it will still blank after a period of time without the intervention of the physical user, despite the video game.

  AFAIK this option is always available when the laptop is preinstalled with Toshiba (factory State) recovery image.
  You install own OS or what?

  I have two Toshiba laptops, and both of them have this option in the Windows Mobility Center.

  Thank you I enjoyed your attention and your support.

  We did a system restore (at an earlier date) and fortunately he fixed itrself. I'm good to go.

• Windows 8 does not not log on screen, all black dekstop, explorer.exe, disc missing from the Task Manager

  Hey. I am a newbie in this forum. And I really like to make my PC more 'me' even though my parents and brother told me that my PC did not differ from how difficult. But, I still like my PC... ^ ^
  But my PC encountered a problem in my birthday (March 8, ehehe just FYI). Its a terrible birthday gift: (...) Oh, there. Its all started when I accidentally install a skin pack or win 7 in my PC 8 victory. There is nothing wrong with installing proggress except a notification which inform on win 7 Starter has not installed correctly. :( Well, I ignored, first. But after I have it reboot, my dekstop went all black but it still can open the Task Manager. And then I try the system restore. It did not work properly. The only thing made worse. Somehow, my "(le seul compte dans mon PC) DELETED account." In fact, the log on screen consist only of the ease of access and power button with backgorund optomistic. Where are the data of the user, I mean a place where we inserted the password? XC its make me super bad mood. And after some restoration system with various restore points, I restarted my PC in safe mode successfully. Yippie, its worked perfectly in safe mode. I created a new account in safe mode. I thought that my problem more but no. and the bad news is that there is only one user account (a new one) in the journal on the screen! It'll be better I have the new account very well work, but it didn't! The dekstop always all black with no taskbar and it's the same problem as the first.
  I am not really confusing. What should I do? Should I remove a skin pack safe mode? or reinstall win 8 in PC COUNTER? Or do something that you already know the guy?
  Help me. I am so irritated by this problem. In any case, I want to ask one last thing, you prefer something after me or just think it was a charitable organization? Well, I just want to know. And I'll do my best to show my appreciation once you help me. I am so TROUBLED even if today is my birthday! I want a big anniversary with neither party. But its seems no big birthday. Please, help me. His will probably be my MOST BEAUTIFUL GIFT to a person who I know in internet. If you need something detailed about my problem, ask me. I need your response. :") SURE ME MY CRAZY MOM, IF SHE KNEW IF I AM WRONG IN MY PC AGAIN.

  Oh, there. The explorer.exe does not start in normal mode, but it works fine in safe mode. Also, I discovered that the disc is missing from the Task Manager. :) Help?

  Wish you a very happy birthday, Damaris.

  Of course, I can understand the situation you're in right now, and it's a shame. I will be happy to answer your query and try my best to offer my help as a gift for your birthday.

  Let me ask you;

  1. What happened when you tried the system restore?
  2. What was the last time that the computer worked well?
  3. What security software is installed on the computer?
  4. Remember to no particular change in the computer before the show?

  The issue may be due to any dispute of third party software, virus or any system or missing files / corruption. Let's try the methods below and check the status.

  Method 1: Since you are able to start the computer in safe mode without any mistake, I you suggest to start the computer in safe mode and then perform the clean boot to avoid software conflicts.

  Step 1: Start the computer in safe mode (as you are able to start the computer in safe mode with the steps you tried).

  Step 2: Perform the clean boot

  To help resolve the error and other messages, you can start Windows by using a minimal set of drivers and startup programs. This type of boot is known as a "clean boot". A clean boot helps eliminate software conflicts.

  Put your system to the clean boot state helps determine if third-party applications or startup items are causing the problem. You must follow the steps in the article mentioned below to perform a clean boot.

  How to perform a clean boot in Windows

  Note: see 'How do I reset the computer to start normally after a boot minimum troubleshooting' to reset the computer starts normally after troubleshooting.

  Method 2: Run Microsoft Safety Scanner

  The Microsoft Security Scanner is a downloadable security tool for free which allows analysis at the application and helps remove viruses, spyware and other malware. It works with your current antivirus software.

  Microsoft safety scanner

  Note: The Microsoft Safety Scanner ends 10 days after being downloaded. To restart a scan with the latest definitions of anti-malware, download and run the Microsoft Safety Scanner again.

  Note: Data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

  Method 3: Run the tool File Checker system in case where any system files are missing or corrupted.

  System File Checker is a Windows utility that allows users to find corruptions in Windows system files and restore the damaged files.

  Enter in the right edge of the screen and then click on Search. Or, if you use a mouse, point to the corner bottom right of the screen, then click on Search. Type the command prompt in the Search box, right click invite, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.

  At the command prompt, type the following command and press ENTER:

  sfc/scannow

  Note: Not close this command prompt window until the audit is 100% full. The results of the analysis will be posted when this process is completed.

  Hope this information is useful. Please feel free to answer in the case where you are facing in the future other problems with Windows.

• on my laptop running windows 7 more information disappeared from the window - topics (file, publishing, display, etc.), address bar and navigation buttons - everything I can see tabs - how do the lack of points to display

  Missing on my laptop running windows 7, all the info displayed at the top of the home page. All headings, i. e. file, change the view etc. disappeared. There is no address bar. There is no "home button", the button refresh, etc.. My wife was using the machine when it happened, so I don't know what she was doing. How to restore these features?

  most of the information has disappeared from the window - topics (file, publishing, display, etc.), address bar and navigation buttons

  When all the toolbars are missing, you are probably in full screen view, press F11 to toggle mode full-screen, or you can move the cursor to the top of the screen.

  The real problems you describe all set thanks to an extension and customization, see 01:10 steps later...

  You can make Firefox 5.0 looks not like Firefox 3.6.19, see numbered 1 to 10 points in the next topic difficulty Firefox 4.0 UI toolbar, problems (Make Firefox 5.0, or 4.0.1 resemble 3.6). If you make changes, you must be aware of what has changed and what it takes to use changed or missing features.

  • http://dmcritchie.MVPs.org/Firefox/Firefox-problems.htm#fx4interface

  It is much more beyond these first 10 steps in the list, if you want to make Firefox more functional.

  Toolbars and their contents have been rearranged and buttons have been merged dual-use, the net result is that I could see about 25% of what I had before and recorded about 10% of the area of the toolbar with great loss of functionality to hide things that might already be hidden and to create confusing buttons that already have keyboard shortcuts and don't need to be seen. The only good thing that has been ' Ctrl + / ' has been added to hide/show the modules bar that has not replaced the status bar.

  If this

  means that you have tried to use sfc/scannow from start > run, your experience is not surprising.  This 'solution' is often suggested by people who don't really understand what this command does.  It does not help to restore a missing rundll32.exe file.

  What is the name and version of your anti-virus application?  When (approximately) their subscription expires? What other antimalware applications installed?  What other antimalware applications you used recently to scan your computer?

  If you have not yet used the "software to remove the REG files and etc." return for refund or throw it out.  "Registry cleaners", 'tuners', etc. are not useful.  If you used to "clean" the registry, use its "undo" feature (if it has one) to restore the registry.  Longtime MS MVP PA Bear:

  TIP: If you still think again your registry database must be cleaned, repaired, amplified, to the point, healed, twisted, fixed, enlarged, "swept" or optimized (it isn't), read http://aumha.net/viewtopic.php?t=28099 and draw your own conclusions.

  What probably happened is that your antivirus application deleted or quarantined in your file rundll32.exe thinking he was infected.  He could have, but probably not.  In any case, read the post that begins, "That 'solution' is not on my list." in the following thread: http://answers.microsoft.com/en-us/windows/forum/windows_xp-performance/systemrundllexe-not-found/6e30aff2-a88e-4d86-a654-753d54f632d1 you can also read the rest of the posts in this thread.

  Note that c:\windows\system32\dllcache is a hidden folder, but you who type in the address bar of Windows Explorer (or copy and paste), the folder should open anyway.

  Assuming you manage to restore rundll32.exe, download, install, update and run full scans (not at the same time) with each of the following free tools.
