Is Home Premium installed or Business installed?
If Home Premium is installed, you cannot move to XP in this direct manner.
If Business is installed, you could. Call up Acer and ask if they have downgrading services available.
Either way, download any Linux distributions, burn it to a CD and install. This will wipe out Vista. After that, install XP.
Make sure you set your CD/DVD drive as the first boot device.
Also,if say i reformat to windows xp,i wont be able to use the recovery CD in future right?
You won't be able to once everything is wiped out.
