I'm assuming that you have the DriveImage XML image you created stored on an external drive. To access that image when needed you
would need to be able to boot the computer from a CD.
You may have created a boot disk using the Acers eRecovery....don't know if the disks you made are bootable.
Or you may have created a bootable disk following the DriveImage XML directions....don't know.
To be sure that you can boot the computer, if the factory install goes bad, and be able to access and use the DriveImage image you created,
follow the directions in link below to create a System Repair Disc.

System recovery options can help you repair Windows if a serious error occurs. To use system recovery options, you'll need a Windows installation disc or access to the recovery options provided by your computer manufacturer. If you don't have either of those choices, you can create a system repair disc to access system recovery options.
To create a system repair disc
Open Backup and Restore by clicking the Start button, clicking Control Panel, clicking System and Maintenance, and then clicking Backup and Restore.
In the left pane, click Create a system repair disc, and then follow the steps. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
To use the system repair disc
Insert the system repair disc into your CD or DVD drive.
Restart your computer using the computer's power button.
If prompted, press any key to start the computer from the system repair disc.
Choose your language settings, and then click Next.
Select a recovery option, and then click Next.
Tip: Print these instructions and keep them in a safe location with your system repair disc.
