Computer Wont boot up after SP3 installation RRS feed

  • Question

  • SP3 was updated automatically in my computer. Now it does not boot up in normal, safe mode or last working configuration.

    It is manufactured by dell and has Intel processor.

    Sometimes it gives blue-screen with some error message.

    What can I do to fix this?

  • 1. First, place the Windows XP installation CD into the CD/DVD drive of the PC and boot the PC. When the message appears on the screen that tells you to "Press Any Key to Boot from the CD", press a key on the keyboard. If the computer is configured with the Recovery Console already installed then instead, boot the computer and just before the Windows XP logo appears press and hold down the F8 key and then select Recovery Console from the menu that appears and press Enter and then enter the Administrator password and skip to step 3.

    2. Next, the software will load from the CD and perform a number of hardware checks and then pause on a screen that asks you what to do next. Select R for Repair and then at the command prompt select the Windows XP installation that you need to recover and then enter the Adminstrator password for the PC and press Enter in order to access the command line.


    3. Now, on the command prompt type: cd\ <Enter>. Next, type: cd system~1\_resto~1 <Enter>.


    4. Now type: dir <Enter>, and a list of restore points will be displayed (named rp1, rp2, rp3 and so forth). Repeatedly press the Enter key to get to the last restore point directory.


    5. Now, type: cd rp(number.of.restore.point) replacing the number.of.restore.point above with the number of the restore point you wish to restore (I suggest using the restore point that is one prior to the last restore point - for example, cd rp5).


    6. Next, type: cd snapshot <Enter>, and you should now see c:\system~1\_resto~1\rp5\snapshot (assuming that drive C: is the system drive where Windows XP is installed.


    7. Now type: copy _registry_machine_system c:\windows\system32\config\system <Enter> and then type: copy _registry_machine_software c:\windows\system32\config\software and press Enter.

    8. Type exit to reboot the computer, and let it boot from the hard drive (remove the XP disk)
