How to Uninstall Windows 8-Install Windows 7 on Your PC
If you're fed up with the
Windows 8 operating system
that came on your new laptop, and just want to switch back to
Windows 7,
I've got good news, and bad news. The good news is that it is possible.
You
can remove
Windows 8,
install Windows 7, and go about your
life as if
Windows 8 never happened. The bad news is that it's a
complicated endeavor.
In addition to the expected BIOS wrangling, drive formatting, and
reinstalling device drivers, Microsoft has actually added extra layers
of complexity. The BIOS has the added obstacle of the Unified Extensible
Firmware Interface (UEFI). Drives are partitioned and protected so that
it's difficult to reclaim all of the space on your hard drive. And
finally, manufacturers are spotty at best when it comes to offering
Windows 7 drivers and rarely support users in making the switch. The
result is a snarled Gordian Knot of complications, but there's not
necessarily a sword available to simplify the issue. This guide,
however, should help you navigate the many twists and turns.
If you don't want to remove
Windows 8 completely but still want to
have your familiar Windows 7 experience, want to avoid compatibility
issues with programs and games, or need a feature that's gone missing in
the new OS, there are other options. Your best bet is actually running
Windows 7 on a virtual machine—and we can suggest several.
If you're ready to embark on the journey back to
Windows 7—it feels
wrong to simply call it a downgrade—then gather your supplies, muster
your courage, and let's dive in.
A Few Words of Warning
Microsoft does offer downgrade rights, complete with support services
and a clear downgrade path to Windows 7, but only for systems with
Windows 8 Pro. If you've just got plain old Windows 8—and most
mainstream systems do—you're on your own. Switching between the two
operating systems is still very doable, but you'll be doing it without
Microsoft's blessing.
Related to this, you may also run into trouble getting support from your
manufacturer, as most do not provide legacy support for Windows 7 on
systems that were factory-shipped with Windows 8. This extends to
drivers. You'll need to do your homework as to what your devices are,
what drivers they require, and whether or not there are Windows 7
drivers available. Unfortunately, this will vary from model to model,
and even from one configuration to the next.
Start by opening the device
manager in your control panel. It will provide you with a list of all
the different devices found on the system, from touchpad and keyboard to
networking and Wi-Fi adapters. Don't skip this step, because you can't
use the device without a working driver—meaning that without the proper
drivers, you can easily find yourself stuck with a nearly unusable
machine.
By digging into the properties of each device individually, you should
be able to find the specific part model name, and information about the
drivers. Some searching online will help you discover whether or not
Windows 7 drivers are available for each part, but you will often need
to track do each driver individually. The one exception to this is when
the manufacturer offers two versions of the same model PC—both a Windows
8 configuration, and a Windows 7 version
The first place to check is the PC manufacturer's product support
page. By looking up your specific PC model number, you should be able to
locate a list of all the needed drivers for the laptop's hardware. If
you're lucky, the manufacturer support page includes drivers for both
Windows 8 and Windows 7, giving you everything you need for your entire
PC. With one of our test PCs, this was all we needed to do, because all
the device drivers were available.
If not, you'll need to take it one device at a time. Find the name of
the manufacturer for each device and search for that company's website,
which should have its own driver download page. If even this doesn't
seem to help, you can always fire up your search engine and search for
"[Device name] + Windows 7 Driver." That should bring up plenty of
resources.
Be aware, however, that for some newer devices, drivers may not be
available for Windows 7 and older operating systems. If this is the
case, you may be out of luck—which is why you're looking all of this up
beforehand.
Backing Up
Back up
everything. Tech journalists often preach the importance
of regularly backing up, but this is more than the usual preparation
against hypothetical disaster—you're about to overwrite your hard drive.
Everything on that drive will be gone. Files, programs, and the
original operating system, all gone. Just because you want to ditch
Windows 8 now doesn't mean you won't change your mind in the future.
Additionally, you may want a way to revert back to
Windows 8 should you
ever need to take advantage of the warranty—there's worry that some
manufacturers will void the warranty on the system if Win 8 is removed.
What You Need
First, you'll need Windows 7 installation media, either on disc or on a USB Key. Yes, Microsoft still sells it, as does
Amazon.
In addition to your installation media, you'll need a valid Windows 7
Product Key, the 25-digit alphanumeric code used to activate your copy
of Windows. If you're installing from a brand-new copy of Windows,
you're fine to use the product key that was included, but if you're
using an older copy (or a copy of a copy) you'll need to pay for a new
valid key.
You will also need a USB key (separate from your installation media)
with drivers loaded on it. This is the result of the aforementioned
homework—you really don't want to install Windows 7 without it.

Open Settings by going to the Charms Bar and clicking on the Gear icon.

Go to "Change PC Settings" at the bottom right corner of the screen,
below the icons. On the left, scroll down and select "General Settings."
On the right, scroll down through the settings options to find
"Advanced Options."

This will close out of the standard Metro interface and open up a blue
screen with several tiles. Select "UEFI Firmware Settings"—you may need
to first select "Tools and Settings" and then "Advance Options"—and then
follow the prompt to restart and change settings.

Upon rebooting, the system should produce a startup menu. Select "BIOS
setup." Under the "System Configuration" tab, find "Boot Options." (In
some instances, Boot Options will instead be found under the "Security"
tab.)

Once into the Boot Options menu, you will first find "Secure Boot" and
disable it. Still in the Boot Options menu, find "Legacy Boot" and
change it to enabled. You will now be able to boot into your Windows 7
installation media. Depending upon whether you will be installing it
from a disc or a USB key, you will want to change the Legacy Boot Order
so that either the optical drive or USB device take priority. Finally,
exit the BIOS, saving changes.
Commence Installing Windows 7
With Legacy Boot enabled and your boot order changed, you should now be
able to boot into your installation media to begin installing Windows 7.

The first thing you'll see is a prompt to begin installation.
Start the installation process, choose your language and region, and press "Install Now" to begin the process.
You'll be asked to agree to Microsoft's software license, and then to
choose between an Upgrade or Custom installation. In this instance,
you'll want to choose Custom.
The next step is to choose the destination drive for the installed
OS. At the very least, you'll want to install Windows 7 to your C:
drive. If you want to wipe
Windows 8 completely off of your system, this
is the time to do it. Select the various partitions on the hard drive
and go through the process of deleting each, and consolidating the free
space. This all handled in the installer, which gives you the option to
delete or format each partition as it's selected. But beware—this is the
Rubicon of OS installation. Once those drives are gone, they are gone,
and rebooting the system without finishing the Windows 7 installation
will leave you with a PC that has no operating system.
Next, the installer will go through the process of extracting and
expanding all of the necessary installation folders. Kick back and relax
for a while, because this part is automatic. During this process, the
PC will also restart on its own—don't panic, that's just part of the
installation process.

Finally, your laptop will boot into Windows, and you should see a more familiar version of the Windows logo come up.
Once you boot into Windows, you'll be asked to provide a 25-digit
Product Key. You can proceed without one, but you'll be forever hounded
by warnings about using a pirated version of Windows, even if it's a
brand new store-bought copy.
Install Drivers from USB key
Once you've got Windows 7 installed on your system, it's time to install
your drivers. As a rule, I always start by installing networking
drivers—once you've got your Wi-Fi or Ethernet connection up and
running, you can hunt down the rest and troubleshoot online as needed.
Once you've got your drivers installed for everything else (trackpad,
graphics processing, USB 3.0 ports, Bluetooth, etc.) do one final
reboot. Viola! You've now got a pristine Windows 7 PC, ready and waiting
for all of your software and files.
Hopefully, this little guide has helped you to navigate the minefield
of switching from
Windows 8 to Windows 7 without the loss of a limb.
Enjoy your Start Menu, and bask in the light of a tile-free existence,
free to use Windows as you always have. With any luck, the next version
of Windows will be a little easier to adjust to.
