OK, we'll try this

To start the System Restore tool from a Command Prompt.

Restart your computer, and then press F8 during the initial startup to start your computer in Safe Mode with a Command Prompt.

Log on to your computer with an administrator account or with an account that has administrator credentials.

Type the following command at a command prompt, and then press ENTER:

%systemroot%\system32\restore\rstrui.exe

Follow the instructions that appear on the screen to restore your computer to an earlier state.


If you can't enter Safe Mode try this.

Boot the system using the Windows XP CD-ROM. In the first screen when the Setup begins, read the instructions press "R" (in the first screen) enter the Recovery Console.

1: C:\WINDOWS

Which Windows Installation would you like to log on to (To cancel, press ENTER)?

After you enter the number for the appropriate Windows installation, Windows will then prompt you to enter the Administrator account password.

Note If you use an incorrect password three times, the Windows Recovery Console closes. Also, if the Security Accounts Manager (SAM) database is missing or damaged, you cannot use the Windows Recovery Console because you cannot have correct authentication. After you enter your password and the Windows Recovery Console starts, type exit to restart the computer.

Type the following command and press Enter.

Type CD\ then Enter

Then type cd system~1\_resto~1 then Enter

Type dir then Enter

When you hit enter it will list all the restore points folders like rp1, rp2 ??.. If the restore points have more than one page then you will have to keep on hitting the <Enter> key to view the last restore point folder. You will have to choose the second to last option folder

Type cd rp {the second to the last restore point no. } (Note: Example: cd rp9, if rp9 is the second to the last restore point where the last restore point no. is 10

Then type cd snapshot

Now the command prompt will look like this c:\system~1\_resto~1\rp9\snapshot

Type: copy _registry_machine_system c:\windows\system32\config\system

Press enter

Then type: copy _registry_machine_software c:\windows\system32\config\software

Then type exit

TIP!.

If you get an access denied error when doing the above, then do the following at the recovery console:

Type CD\ then press Enter

Type cd windows\system32\config then press Enter

Type ren system system.bak then press Enter

Type exit and press Enter

Your PC will reboot, go back into the Recovery Console and then you have access.

This if you can follow it

Turn on your System and press the eject button on your CD/DVD optical drive. Insert your XP CD and close the drawer.

If you were quick enough you should get a <u>prompt</u> to press a Key to boot from CD/DVD. Press a Key like the Spacebar or the Enter Key.

If you miss the <u>prompt</u> restart the System by pressing the Reset button. Do not remove the CD as this is what you want to boot from.

System does not boot from CD?

by seanferd In reply to the cd drive....

You may have to go into BIOS setup and allow computer to boot from CD drive. Also, CD drive should be before HDD in boot order.

Watch when computer boots to see something like, "Press (some key) to enter setup".
