Hi,
Last night, I took an old computer that had XP Pro. on it and downloaded a ton of updates for the OS. Today, it started up fine, but when I tried to uninstall something (Picasa) it froze. I restarted and got the message: Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key. This was someone else's computer and I don't have the XP SP3 disc. I also noticed the drive was not showing up in the BIOS.
Thanks
