I have an Acer Aspire One 722-0473. My hard drive has died so I will be getting and installing a new hard drive. I am assuming I need recovery disks in order to get the operating system on the new hard drive. I looked on acer.com for the erecovery disk and when I input my SN it only offers me the CD bundle. My netbook does not have a CD drive so shouldn't it allow me to get the thumb disk. Do I even need it or is there a way to get windows on the new hard drive? I have the Product Key on the bottom of the computer.
