It's only remaining steps are to install the factory bloatware which most tech enthusiasts avoid by doing a Clean Reinstall - Factory OEM Windows 7.
This is a vastly superior install which actually allows the user to enjoy native Win7 performance, which a factory install like Acer's doesn't come close to.
You can try running Recovery again from its hotkey at boot, or using the Recovery Disks you should have made as a backup. If you did not then these can sometimes be ordered from Acer. When running them it may be necessary to first wipe the HD with Diskpart Clean Command
to clear old boot code and the partition table to allow Recovery to proceed. Since you need the Win7 disk or Repair CD Command Line to wipe the disk you might as well do the Clean Reinstall.
