Welp, just finished reverting my new laptop from the hated Win 8 to Win 7. Thought I had all the drivers loaded on a DVD but noooooo...... The wireless driver was missing. Spent 2 hours trying to find it online before I gave up and downloaded a "free" driver tool that found it for me, after installation and much fussing and cussing I finally got it to recognize my wireless homegroup connection. Still have 16 more driver updates to download and install but the free version will only allow 2 downloads a day.......

As it was it took hours for everything as I had to call Dell Support to find out how to get into the boot sequencer, M$ changed it with Win 8 and I couldn't find out the steps online.
Yeah, I know some of this is pure Geekinese to some of you so drivers are "programs" that make the hardware work. A boot sequencer tells the computer where to look for the operating system (in this case Windows) on start up, generally it's set to look in the hard drive, if you're installing a new operating system you want it to look in the CD/DVD drive first so it won't default to the existing operating system on the hard drive.
