[Windows 10 Tip] - Dual Boot Setup
This article kicks off a new series of weekly Windows 10 tips, because it’s about time we started getting used to the future of personal computing. Whether we like it or not, Windows 10 is taking over the PC world. If you have already upgraded to Windows 10, you may find in this series help with difficulties that continue to plague you. If you have yet to take the plunge, this series will help you install and learn Windows 10 systematically, without giving up your beloved Windows 7. Read on...
Dual Booting Windows 7 and 10
As of May 2017, Windows 10 installations are up to nearly 27% and climbing. In January 2020, support for Windows 7 will end. If you buy a new PC now, it will come with Windows 10. Resistance is futile, so let's learn how to set up a dual-boot PC, so that you can choose between Windows 7 and 10 whenever you reboot your system.

Of course, you can always take the plunge and upgrade to Windows 10 without a dual-boot system. That will be covered next week.
PREPARING YOUR HARD DRIVE - Windows 10 requires at least 16 GB of disk space, according to Microsoft; for acceptable performance, most experts recommend at least 20 GB. If your C: drive has less than 20 GB of free space, do some housecleaning to move or delete unnecessary files.
JDiskReport can find duplicate files, or sort files in order of size to help you figure out where all that disk space is going. I use JDiskReport several times a year, and I always find gobs of files that can be deleted. Privazer is another excellent utility for clean-up and privacy purposes.
The next thing we’ll do is defragment and optimize our C: drive to prepare for a new partition that will hold Windows 10. That's especially important after deleting lots of unwanted files. It's true that Windows Vista and later versions include a defragger which runs automatically. But word on the street is that it's not exactly best of breed. So for this task, you can use iObit’s Smart Defrag utillty http://www.iobit.com/en/iobitsmartdefrag.php or Defraggler http://www.piriform.com/defraggler from Piriform. Both are free, and compatible with solid state (SSD) drives.
You'll note that some blocks of data cannot be moved because they contain data that is currently in use, or that must remain where it is so Windows can find it during startup. When you’re done with those steps, you'll have a hard drive that's slimmed down, and a computer running like it’s fresh out of the box.
Create a New Partition for Windows 10
Now we’re ready to create a new partition using Windows 7’s built-in disk management tools. Click the Start button and in the search box type “partition,” then double-click on “Create and format hard disk partitions” in the search results. That will open the Disk Management utility. You should see a display like the one below.
Select the C: drive in the lower part of the display; crosshatches will appear to show the C: drive is selected. Now, on the menu bar select Action, then All Tasks, and then Shrink Volume. Wait a few minutes while Windows figures out how much you can shrink volume C.
When you see the display showing total size, size of available shrink space, etc., enter the number of megabytes by which you wish to shrink volume C. That will be the size of the new volume on which Windows 10 will be installed.
I have plenty of space on this drive so I just divided it equally between volume C: and the new partition. Just be sure that you leave at least 20GB for your new partition. Finally, click “Shrink” and wait while it happens.
Select the unallocated space in the lower part of the display; crosshatching will indicate it is selected. On the menu bar, click Action, then All Tasks, and finally New Simple Volume. Follow the wizard’s instructions. When prompted, select “Assign the following drive letter” and use the default letter, usually D.
On the next screen, the default formatting options are fine. You may want to change the volume label to “Windows 10” or whatever you like. Then click Next. Finally, click Finish after reviewing the parameters of the new volume.
After a short wait, you’ll see the new drive letter D: and its volume name in Disk Management’s map. Now you can close Disk Management. Drive D: is where we’re going to install Windows 10 next week. See you then!
