How do I restore a backup made via the Dell USB Key Solution?

I was not able to complete the full running of the Dell Direct USB Key solution because of various issues.  .    Dell ended up sending me a new Windows 7 imaged HDD drive.   I now have the laptop up and running again with Windows 7and have various applications installed.   That is all pretty good.  But now how do I get my data files restored?   Basically I want to connect the backup external drive and complete Step 19 of the solution as described below.

 
Here are the steps OS using the Dell USB key: 
 
1. Boot from the Direct USB Key by tapping F12 at the Dell logo, then select the 
USB Memory Key option from the boot device menu. 
 
2. Accept the Dell End User License Agreement (EULA) by clicking the box next to 
Accept, scroll down till the end of the license agreement and then click on 
continue. 
 
3. On this screen, the usb key gives an overview of the process it is about to 
perform, click continue when ready to proceed. 
 
4. The Smart Repair solution runs a surface scan on the system to identify any 
errors with the boot record or the startup files. If any errors are found, they 
are automatically corrected. 
 
5. Once the process completes, there will be an analysis summary, in this case, 
there is no issue found by the smart repair, click continue. 
 
6. In this window the user can select what data they would like to back up, they 
can either go with the default backup solution or they can click select more to 
select more files for backup, click continue after selecting files for backup. 
 
7. If user clicks on select more, they will get the screen below, they can go 
ahead and select the necessary data for backup by checking the box next to the 
respective folder, sub-directories are selected by default once the root folder 
is selected. 
 
8. The user will be prompted to attach a USB hard drive to the system, user 
needs to connect the USB Hard drive at this point and click continue. 
 
9. Once the solution detects the USB hard drive , it goes ahead with file 
backup. 
 
10. Once the files are backed up, the solution will back up the user personal 
settings. 
 
11. The Direct USB Key displays a summary of the data and personal settings 
backup. Click continue. 
 
12. The Direct USB key then proceeds to install the operating system image on 
the system. 
 
13. Once the operating system image is transferred, the drivers are also 
transferred. 
 
14. After the operating system image and driver transfer, a summary page comes 
up giving the user information as to what process was performed successfully and 
what failed. The user needs to remove the USB key at this point and click 
restart. 
 
15. The system restarts and comes to a flash screen on recovery and restore. 
 
16. After the flash screen, the applications start installing. 
 
17. Once the applications are installed, the user would see a summary screen 
informing them that the Operating system has been restored, connect the Direct 
USB Key and click restart. 
 
18. After the restart the user will be prompted to connect the data backup hard 
drive and then click continue. 
 
19. The files and personal settings are then restored from the USB backup drive. 
 
20. After the files are transferred the system comes to the desktop with a pop 
up window informing the user to check the device manager for any exclamation 
marks, the tool also guides the user to download the drivers from the support 
site and the applications from My Dell Downloads and Dell Digital Delivery. User 
needs to select the check box to prevent the message from being displayed again 
and click close.
