I'm not sure why no-ones replied to this but if you are still having difficulties, please provide the hardware IDs:

That's the hardware Ids for your hard drive and not the network controller.

Okay that's the Dell Wireless 1501 Card and Intel Management Engine Interface. Drivers wise if you haven't done so already, you should install the following.

Ensure that the drivers extract and install and not only extract. An example is given in this video:

Dell Webcam Central should be obtainable in My Dell Downloads, see here for details:

I usually don't install any other preinstalled software from My Dell Downloads especially McAfee which will ruin the performance of your system.

Finally once Windows is setup and everythings working correctly install the latest version of Dell Backup and Recovery - see here for details:

Your BIOS version is already at the latest revision so don't worry about the error message. The driver for the Dell Wireless 1501 hasn't installed correctly. Retry installing the driver I mentioned above. If it doesn't work try the older version here:

http://downloads.dell.com/FOLDER87841M/2/R258276.exe

Install Dell Backup and Recovery only when the system is working 100 %.
