Hello Begale2

Thanks for getting back with information:

I have put together steps on what can be done now one is for system restore and the other pc restore in vista. System restore is the most common one in Vista used by popular demand it seems at times. I hope you have the Vista installation DVD because you will need this to do it.
First you will want to get into you bios and change your boot order so the DVD starts first. Then once the DVD starts access WinRE from the Windows Vista installation DVD is easy. Once it boots up you will be asked for your information.
Make sure that your information is correct and click next. WARNING Whatever you do, do not click the Install Now link or you will end up re-installing Vista. You will want to, click the Repair Your Computer link found in the lower left corner of the screen.
Then you will see a screen asking you to select the OS installation that you want to repair. Your screen may be a blank operating system list if the OS resides on a disk array that Windows does not have a built-in driver for. But, you are given the chance to provide WinRE with a device driver before continuing.
So, if your target operating system is not listed, don't give up hope nothing is lost. Even if the operating systems are not listed, you can still click next and gain access to WinRE.
When you click Next, Windows takes you to the main WinRE screen. There, WinRE gives you a lot more options than the Windows Recovery Console does. You still have the option of accessing a Command Prompt window, you will notice a majority of the restrictions that were present in the Windows Recovery Console have been removed.
Only the Command Prompt environment existed in the Windows Recovery Console. The Command Prompt is one of several options that are available in WinRE.
How to use Startup Repair
In WinRE, it sounds like you are going to be using the Startup Repair option. This option is that if Windows won't boot properly, you can boot WinRE and then choose Startup Repair to perform a series of tests. Startup Repair will then attempt to automatically correct the boot problem.

How to use System Restore
Windows is designed to create system restore points that allow you to roll back the configuration to a previous state should something go wrong? However, some configuration changes can result in a catastrophic failure that leaves a system unbootable. The System Restore option allows you to roll back the operating system's configuration to a prior state, even if the system is unbootable.
When using WinRE System Restore option, remember this: It has one shortcoming. When you perform a system restore through Windows, you have the option of undoing the restore if it does not accomplish what you had in mind. However, when you perform a system restore through WinRE, you are performing an offline system restore, and undoing it is not an option.
Windows Complete PC Restore
Occasionally, you may run into a problem with Windows Vista that you simply cannot fix. In that situation, use the Windows Complete PC Restore option to restore a backup. .Using the Windows Complete PC Restore feature, though, you can restore a backup without having to install Windows first.
I hope this helps and gets your system back up there running and if I can be of any further help let me know als let me now how you make out with it.
Bill

Acer L100 will only start in safemode when I press the F8 key, switches off if I try normal mode


Check your documentation; that may be a safeguard because there is a problem or corruption in Windows, so it auto-starts in safe mode so that you can troubleshoot. I am just guessing. Safe mode loads only the bare essential drivers to get Windows running, all peripherals are blocked because one of them is crashing Windows. I am just guessing, so check your manual that came with the computer. What you can do is a system restore to an earlier date; hopefully that will take care of it.

spacer.gif How to troubleshoot Windows XP startup problems, spacer.gif spacer.gif spacer.gif
spacer.gif
splash_icon_quick_poll.gif CHECKLIST ib_right_arrow.gif How to troubleshoot Windows XP startup problems
One of the most common troubleshooting issues in Windows XP is the failure of a system to start up properly. These failures can be caused by a number of issues, including poorly written or malicious software, faulty device drivers, hardware incompatibilities, corrupt or missing system files and incorrect system configurations. Determining the source of the startup problem, and fixing it, is easier if you use a methodical, step-by-step approach.
If the system will not start in Normal Mode or Safe Mode
A Windows XP system that will not start in Normal or Safe Mode is not a good sign and may be the result of corrupt or missing system files, a corrupt registry, hardware drivers or failed services. Your first step is to press F8 during Startup and select the Last Known Good Configuration option from the Windows Advanced Options Menu. If Windows boots normally, check the event logs and hardware manager for clues as to what may have caused the failure. You may also want to check the Add/Remove Programs menu for any new applications that may have contributed to the failure.
If the Last Known Good Configuration fails, the next step is to start the Recovery Console by booting from the Windows XP Startup CD and pressing "R" to repair when the "Welcome to System Setup" screen appears, then press "C" to start the Recovery Console. The Recovery Console is a command line utility that can be used to identify and solve a number of issues in the event that Windows cannot start, including starting and stopping services and drivers. If you receive an error on startup stating that a system file is missing or corrupt, Recovery Console can be used to replace those files as well. For a list of available commands, simply type HELP at the command prompt. For more detailed information about the Recovery Console, check out Microsoft Knowledge Base article 307654.
If you are unable to determine if a driver or service is responsible for the startup failure, you should run the Checkdisk utility from the Recovery Console by typing CHKDSK at the command prompt. This utility scans your hard drive and checks for problems with the disk or file system, which may result in corrupt or missing system files. You should also check the system CMOS and BIOS settings for configuration errors or corrupt data. Note: CMOS and BIOS data corruption can occur as a result of a dead or weak internal battery. Check your motherboard documentation for details.
If you are still unable to determine the cause of startup failure at this point, you have the following options:
  1. Use System Restore to return your critical system files and some program files from a previous restore point. I've had mixed results with System Restore, but at this point, it is still worth a shot. System Restore can be activated from the Recovery Console. The advantage of using System Restore is that your personal files located in My Documents will not be overwritten or deleted. More information can be found in Microsoft Knowledge Base article 306084.
  2. Restore from a backup tape: While this method will recover your system, you will lose any data stored on your workstation that was created after the system was backed up. This method will also not help you identify the root cause of the startup failure, which may occur again.
  3. Perform an in-place upgrade (reinstallation): This process reinstalls the operating system but may result in data loss if not done correctly. The advantage is that it should return the workstation to a bootable state in which important files can be copied. Applications, service packs and system updates may need to be reinstalled for the system to function properly. For more information, see Microsoft Knowledge Base article 315341.
  4. Perform a parallel installation: A parallel installation involves creating a second Windows XP installation on the same workstation, either in a new folder or on a secondary (slaved) hard drive. The advantage of this approach is that it allows data to be recovered on the primary drive, assuming disk failure was not the cause of the startup issue. After any critical data is recovered, the original installation can be restored from backup source and updated with the new files.

Enter password unlock system


Getting locked out of your Gateway computer can be frustrating, especially when you have school or work deadlines.
You can get locked out of your Gateway computer in cases where a password-protected screensaver became corrupt, or if the you have set the default screensaver to use a screensaver that does not exist.
Gateway computers come with Microsoft Windows XP and 2000, including the professional versions of both.
Knowing how to unlock your a Gateway computer can save you time and irritation.

Press the "Ctrl," "Alt" and "Delete" keys on your keyboard simultaneously to unlock your Gateway computer.
Type the last logged-on user's login information and click "OK" if you see a locked computer message along with "Only domain/username or an administrator can unlock this computer."

Press the "Ctrl," "Alt" and "Delete" keys once again when you see the Unlock Computer window disappear.
Log on as usual.

Method 2

Shut down the locked Gateway computer by using the Microsoft Windows Resource Kit Shutdown tool. This tool shuts down and restarts a Windows 2000- or NT 4.0-based Gateway computer. Note the dialog box that comes up called System Shutdown.


Wait for the shutdown timer to run out and see the Welcome to Windows box displayed on the screen.


Press "Ctrl," "Alt" and "Delete," which unlocks the computer.
Log onto your Gateway computer normally.

Method 3: Backup, Modify and Restore the Registry

Click "Start" and "Run," then type in the command below in the field box exactly as printed:
%SystemRoot%\system32\restore\rstrui.exe


Click "Create a Restore Point," then click "Next" on the Welcome to System Restore page that appears.


Type any name for the restore point, then click "Create" on the Create a Restore Point page. Click "Close" after creating the restore point.
Perform this procedure before you make changes to the registry, just in case you make an error; otherwise, incorrect registry changes could create serious problems with your computer.


Click "Yes" if you receive a prompt to turn on System Restore at this point.
Clear the "Turn Off System Restore" check box by clicking on it, then click "OK," and repeat.


Click "Start," then type "regedt32.exe" (without the quotes) in search field box to modify the registry and unlock the computer. Press the "Enter" key on your keyboard.


Locate the scrnsave.exe value under the registry key below:
HKEY_USERS\.Default\Control Panel\Desktop


Click "String" on the Edit menu, type "logon.scr" (without the quotes), then click "OK."


Look for the ScreenSaverIsSecure value, then click "String" on the Edit menu, type "0," then click "OK."


Quit the Registry Editor


Click "Start" and "Run," then type the command below exactly as printed to restore the registry, then click "OK":
%SystemRoot%\System32\Restore\Rstrui.exe


Click "Restore My Computer to an Earlier Time" on the Welcome to System Restore page, then click "Next."
Note your computer may already be selected to restore to an earlier time--in this case, just click "Next."


Click the system checkpoint on the Select a Restore Point page.
Click "Guided Help (Registry Backup)," then click "Next" on the "On This List Select the Restore Point" area.
Click "OK" if you see a System Restore message listing all the configuration changes it will make.


Click "Next" when you come to the Confirm Restore Point Selection page.
System Restore will now restore the Windows XP configuration you had at an earlier time, and then it will restart your Gateway computer.


Log onto your computer as usual, and then click "OK" when you see the System Restore Confirmation page.

If it looks like this picture, What your seeing is colloquially known as the 'blue screen of death.' It usually means that whatever kind of corruption is in your file system is only repairable through a full format. But first follow these steps:
If you are able to access the BIOS menu (usually holding down either F2 or F12 on startup) try booting in safe mode. If that has no success, try booting from your operating system disc. This problem is common in old computers and is a sign of the end of its life-cycle. Consider purchasing a newer model.

I am not able to get the the start menu black screen ?


Your windows operating system is currupted. Try press f8 after posting screen if that works, and go into safe mode and go from there on. If your operating system doesn't prompt safe mode screen or anything after that... then your windows is corrupted and needs repair or restore. With some Hp computer, restore/repair option is in a hidden partition and you can recover this method at the hp logo via a F fuction key prompting to press for recover/setup/repair. Follow instruction and it should help you out. If there isn't that option, then your kind of out of luck, and a full windows installation is required.

Sounds like your registry may be corrupt. Might have been caused by a virus. Try booting up in safe mode. If you can do that, try running an antivirus program. If it does not boot up then, you may have a more serious problem which requires a windows repair. If it does not boot in safe mode, try booting up off your Windows install disk and follow repair instructions from there.

The file in computer missing or corrupted


Will it boot to safe mode? If so, run chkdsk and have it do a through scan and fix all errors. You can do this via a bootable rescue disk or the Windows CD if safe mode does not work either.

If running chkdsk doesn't work, you'll have to extract the missing files from the Windows CD using the Recovery Console. If that doesn't work, then it's time for a repair install using the Windows CD.
