    Hi,

     

    Are you unable to start the computer after installing Windows Vista Service Pack 1 (SP1)?

     

    If so, let’s start WinRE using either of the following methods:

     

    a.    Boot from a Windows Vista installation DVD and choose Repair.

    b.    Use the startup menu to launch WinRE on an OEM computer with WinRE installed to the hard disk.

     

    Then start System Restore from the WinRE interface. Restore the system to the “Windows Vista Service Pack 1” restore point.

     

    After the system is restored and we can boot the system, please refer to the following article before reinstalling SP1:

     

    Things to Know Before You Download Windows Vista SP1

    http://msdn2.microsoft.com/en-us/windowsvista/bb968895.aspx

     

    Installing SP1 requires a minimum of 5 GB free disk space on the Windows partition. The recommended free disk space is as follows:

     

    • 7 GB Recommended for 32-bit Windows Vista

    • 12 GB Recommended for 64-bit Windows Vista

     

    If your original system is an OEM (Original Equipment Manufacturer) version preinstalled in the computer, I recommend contacting the computer manufacturer before installing Windows Vista SP1. Please ask them if any of the software applications and hardware drivers need to be updated for Vista SP1. Otherwise, installing Vista SP1 may cause unexpected problems.

     

    The installation may take more than 45 minutes, depending on the system. The system will reboot several times during the installation. Please do not turn off the power manually. If we are using a laptop, please connect it to the AC Power Adapter.

     

    At this stage, I recommend downloading Windows Vista Service Pack 1 in Normal Mode and installing it in Clean Boot Mode. Please follow the steps below.

     

    Step 1: Download Windows Vista Service Pack 1 Standalone Installer

    =============================================

    1. Download Windows Vista SP1 from the link below according to your System Type:

     

    Windows Vista Service Pack 1 for Windows Vista 32-bit (Size: 434.5MB)

    http://download.microsoft.com/download/3/a/9/3a9b72c2-527d-4694-8a49-84c056d4c34d/Windows6.0-KB936330-X86-wave0.exe

     

    Windows Vista Service Pack 1 for Windows Vista 64-bit (Size: 726.5MB)

    http://download.microsoft.com/download/8/3/b/83b8c814-b000-44a4-b667-8c1f58727b8b/Windows6.0-KB936330-X64-wave0.exe

     

    2. Please save it on the Desktop.

     

    Step 2: Clear up Windows Update temporary folder

    =================================

    1. Close all the open windows.

    2. Click the Start Button, click "All programs", and click "Accessories".

    3. Right-click "Command Prompt", and click "Run as administrator".

    4. In "Administrator: Command Prompt" window, type in "net stop WuAuServ" (without the quotes) and press Enter.

    5. Click the Start Button, in the "Start Search" box, type in "%windir%" (without the quotes) and press Enter.

    6. In the opened folder, look for the folder named "SoftwareDistribution".

    7. Right-click on the folder, select Rename and type "SDold" (without the quotes) to rename this folder.

    8. Still in "Administrator: Command Prompt" window, type the command "net start WuAuServ" (without the quotes) in the opened window to restart the Windows Updates service.

     

    Step 3: Install Windows Vista SP1 in Clean Boot mode

    ===================================

    Please disable all startup items and third party services when booting to avoid conflict when installing Vista SP1:

     

    1. Click "Start", type: MSCONFIG in the search box and press Enter.

     

    Note: Please click "Continue" if the "User Account Control" window pops up.

     

    2. Click "Services", check the "Hide All Microsoft Services" box and click "Disable All" (if it is not gray).

    3. Click "Startup", click "Disable All" and click "OK".

     

    Note: Temporarily disabling the Startup Group only prevents the startup programs from loading at startup. This shouldn't affect the system or other programs. We can manually run these programs later.

     

    4. Please double click the downloaded Windows Vista Service Pack 1 Standalone Installer and follow the instructions to install Windows Vista SP1.

     

    Note: To restore the computer to use a Normal Startup, repeat step 1 above. Then click "Normal Startup" on the General tab, click "OK", and then restart the computer.

     

    What’s the result?

     

    Hope it helps.
