I've had to run KillDisk on the computer to remove unwanted Spanish programs and operating system.

Now I cannot install Windows XP. I have set BIOS to default settings, and I have tried the Ctrl+F11 Restore suggestions without success.

When I boot the computer with the O/S disk in the drive, I get a message "Error al cargar el sistema operativo". I have also tried booting the O/S disk from an external USB CD/DVD drive with the same results.

Can you help me please.
