If your CD is starting from within Vista, you won't have the option to
install XP, you have to boot from the CD.
After POST, but before XP loads, you need to hit whatever key Acer uses to
access setup/BIOS.
Depending on the manufacturer, it can be DEL, F2, F10, whatever shows on the
POST screen.
In the 'boot order' section of the BIOS, set the CD/DVD drive as the first
boot device.
Save and exit BIOS.
Once the machine boots from the CD, you should have the option to install
XP.
If that fails....
If you have the original restore disk for the laptop, you should be able to
restore the system to the factory state using it.
If not, you may need to get one from Acer.
