• Insert the Windows OS CD in the CD drive of your computer, and then restart your computer.
  
• 2 Press "R" on your keyboard when you see the Windows XP( if your OS is XP) "Welcome to Setup" screen. This will start the Windows XP recovery console. If you are asked to enter the administrator password, type it and press "Enter."
  
• 3 Type the following commands one by one, without quotes, at the command prompt, and then press "Enter."
  "EXPAND drive_letter1:\i386\user32.dll_ drive_letter2\windows\system32"
  "EXPAND drive_letter1:\i386\userinit.ex_ drive_letter2\windows\system32"
  Replace drive_letter1 here with the CD drive letter of your computer in which the Windows XP setup CD is present (for example, E:), and drive_letter2 here with the letter of the drive in which Windows XP is installed on your computer

If you have compressed the hard disk drive using the Compress drive to save disk space option under the Properties menu for your hard disk drive and have performed a non-destructive recovery or a system recovery, the following error message may appear: NTLDR is compressed. Press CRTL-ALT-DEL to restart. This error message is resolved by following these steps:

1. Insert the HP Recovery Tools CD or Compaq Recovery Tools CD into the CD drive on the computer and restart the computer.Wait for the HP Recovery Tools CD or Compaq Recovery Tools CD window to open.
2. Select Run Microsoft Recovery Console , click Next , and then follow the onscreen instructions. NOTE: If you are unable to open a recovery console, follow the Alternate steps .
3. Press R to repair the Windows XP installation using Recovery Console.
4. Enter the appropriate number for the WINDOWS installation, for example, the WINDOWS installation could be listed as 3: C:\WINDOWS or 3: D:\WINDOWS .

Alternate steps NOTE: These alternate steps work for HP and Compaq desktop PCs with Windows XP and a recovery partition.

These steps do not work if you have replaced the hard disk drive, replaced Windows with another operating system, or repartitioned the recovery partition.You can use the following steps if you are unable to open a recovery console:

1. Turn on the computer. When the initial logo screen appears, press the F10 key repeatedly until a message about starting recovery appears.
2. At the Recovery screen, click Advanced Options and then press the Alt and D keys at the same time to go to a command prompt.

8. At the command prompt, enter the following: cd \windows\system32
9. At the command prompt, type the following: compact ntldr /u <the drive letter>:\ntldr For example if the drive letter was H, you would type: compact ntldr /u h:\ntldr
10. Type exit and press Enter .
11. Click Quit .The error message should be resolved.

best thing to do if you can get one is a propper install disk and then follow these instructions..


1. Start the Recovery Console. If you do not have the Recovery Console installed, start it from the Windows Xp compact disc (CD). To do this, follow these steps:

a. Insert the Windows XP CD and restart the computer. If prompted, select any options required to boot from the CD.

b. When the text-based part of Setup begins, follow the prompts; choose the repair or recover option by pressing R.

c. If you have a dual-boot or multiple-boot system, choose the installation that you need to access from the recovery console.

d. When prompted, type the Administrator password.

2. At the command prompt, type "cd \" (without the quotation marks), and then press ENTER.

3. Type "ren ntldr ntldr.old" (without the quotation marks), and then press ENTER.

4. Type "map" (without the quotation marks), and then press ENTER.

5. Note the drive letter assigned to the CD-ROM drive that contains the Windows XP CD. It is displayed in a format similar to the following: D: \Device\CdRom0

6. Type "expand <drive>\i386\ntldr._" (without the quotation marks) (where <drive> is the drive letter of the CD-ROM drive that contains the Windows XP CD), and then press ENTER. For example:

Expand d:\i386\ntldr._ <ENTER>

Note the underscore character after the "."

The following message appears: ntldr, 1 file(s) expanded.

7. Type "exit" (without the quotation marks). The computer restarts.

8. Remove the Windows XP CD and start the computer normally.

Try starting your PC in Safe Mode.

To get into the Windows 2000 / XP Safe mode, as the computer is booting press and hold your "F8 Key" which should bring up the "Windows Advanced Options Menu" Use your arrow keys to move to "Safe Mode" and press your Enter key.

Safe mode takes a while to load but once it is loaded, I think you can use control panel to get to "add/remove programs" - then hopefully you can uninstall "screen on password"

Hello Ganguly

You likely need to enable legacy (older technology) USB devices in your desktop computers' BIOS.

How to enter the BIOS of your particular computer will depend upon its motherboard and BIOS.

HERE is a link to a site w/ a listing of BIOS manufacturers and how to enter their BIOS.

You can identify your motherboard and BIOS by running the free BELARC ADVISOR PC audit utility found HERE.

The BIOS is entered normally during POST (right after powering on or restarting the computer - while the screen background is still black).

It is during this period that you must strike the key or key combination required to enter the BIOS.

If you need assistance w/ this, please, run the BELARC ADVISOR PC audit utility and let us know what motherboard & BIOS is installed on your computer. Or, if yours is one made by a major manufacturer (Gateway, Dell, IBM, etc.), let us know the manufacturer, model, and serial number or service tag of the computer. W/ that information we'll likely be able to find out how to enter your computer's BIOS.


Please, let us know if this response was helpful for your or, of course, if you have more questions, etc on this topic.

Thank you
BJ
