Installing Windows 7: First you need to verify and if necessary change the boot order in the UEFI settings so that your PC will boot from the DVD drive (or USB device if you created a bootable USB Flash drive). You can do this by making the DVD drive / USB device the first device listed in the boot order and the hard (or SSD) drive your second device, exit as save the changes.
User who have a standard BIOS (usually found on most pre Windows 8 systems) from Windows 10, insert the Windows 7 DVD. If the AutoPlay window opens, do nothing except to close it; now reboot the computer.
For computers that are UEFI based (Does not have a standard BIOS found earlier / pre Windows 8 based computers) you will need to select the appropriate boot device.
If you see the “press any key” message displayed.
1) Press the keyboard’s space bar several times and wait for the “Windows” Logo / splash screen to be replaced (this may take some time) by the Windows 7 Language, Time and currency and the Keyboard setup screen. Make any changes (if needed) and click the ‘Next’ button.
2) Click on the “Install now” option located in the center of the screen.
3) Read and accept the License terms and click ‘Next’.
4) Which type of installation do you want? Choose the “Custom: install Windows only (Advanced)” option.
5) Where do you want to install Windows? Select / highlight the partition named (Win7) or the “Unallocated” space you created by shrinking the Windows 10 partition.
Click ‘Next’ to continue.
If you see the warning message below click ‘OK’ to proceed. This message is the result of installing an older version of Windows after Windows 10 has already been installed.
6) Windows 7 will now start a series of installation steps, followed by a restart / reboot of your PC.
Copying Windows files. Getting files ready for installation Installing features Installing updates (Automatic reboot, no action required on your part) Finishing up Windows will now restart
Note: From this point on, if you see a prompt like the two shown below, take no action, don’t touch the keyboard.
By default the Windows 7 will continue the installation process, just wait for the timer to expire. You may have noticed the graphical (GUI) boot menu is replaced by the text based menu. This is a result of Windows 7 being installed last (After Windows 10).
7) After Windows 7 has finished the installation process: You should boot to Windows 7 you will need to install your Device Drivers for your computer’s (HP, Dell, Acer, Toshiba, Etc.) or if built your own system the drivers for motherboard manufacture’s make and model , starting with the Chipset driver, LAN, USB, Audio, Etc .
Install Windows Updates in small batches of 20 at a time, saving the .NET Framework updates for last. It is a time consuming task, but you are less likely to have problems. I’ve noticed that some updates fail to install, but when trying a second time they install without any issues.
Install any applications that need to run in a Windows 7 environment and verify they function properly.
That’s it; you have completed the Windows 10 / Windows 7 dual boot installation.
