Acer's website, and go from there

I should have read closer. If your recovery partition is gone, there is no
way to recover the original setup. The disk needs it as I said above. You
will likely have to buy a copy to the operating system, and download all the
drivers from Acer's website, and go from there. BUT, if it's still in
warranty, you could send it back and they can probably put the original
image on the drive again, or do it for a fee out of warranty. Without the
partition, the disks are useless.
