I asked you how exactlly you created the stick.
Set the IDEO Seagate hard drive as first boot device. Save changes and exit.
Now plug in the stick, reboot and tap the F12 key to get the Acer Boot Menu. If the stick is done correctly it should show up probably under USB HD Flash Stick, but may be listed under another HD requiring expanding the listing to see it, or be listed under USB or Removable. Normally the name of the stick also appears.
If the stick doesn't appear download a new ISO for your licensed version Win7 Home Premium x64 SP1 English Official ISO download and write the stick again using UltraISO Software To Create Bootable USB Flash Drive making sure to use the Format button before Write.
Then look for the stick again under the F12 Boot Menu.
If it doesn't show up then enter BIOS setup again and check settings for USB on all tabs - there will be multiple tabs across the top to click on.
