You might have been able to re-install Vista via the hidden hard drive partition; however, now that XP has been installed, the HP Master Boot Record (MBR) has been overwritten. The F10 key (for system recovery) at start-up probably won't work anymore. You can purchase HP installation disks from HP if you failed to make them when you first got the computer.
(1. ) You will need to obtain the Windows XP network card drivers for your Sony Vaio by going to the Sony website
and entering your computer model number. You will need to transfer these to a USB flash drive to install on the Vaio without internet access.
(2. ) Windows Update
does NOT work on a computer that doesn't have Windows XP, Service Pack 3 (SP3) installed.
Note: I may lose power as I am on the Northeast Coast and Sandy is rapidly approaching.
- On a computer with internet access, download Internet Explorer 8.0 from here (download link at top right).
- Next, determine what service packs are installed on your Windows XP installation:
- Click Start and right mouse click on on My Computer icon on Desktop or My Computer in the Start Menu.
- Click Properties. On the General tab under System, it will report what service pack is installed.
- If no service packs are listed, then you don't have any installed.
- You must have at least Service Pack 1 installed before you can install SP3. You do not need SP2 if you have SP1a installed. If no Service Packs, try SP2, then SP3.
- You can download SP2 from here.
- You can download SP3 from here.
- Transfer the files to a flash drive.
- First, install IE 8.0 on the Vaio.
- Second, install Service packs as necessary.
- Finally, use Windows Update on the Vaio to download all remaining updates.
