Windows 10 is the next version of Windows Operating System after Windows 8.1 which aims to bring a lot of desktop functionality back to the hands of users using a mouse and keyboard with their Windows PCs. However, it will not suite everyone (at this stage) due to hardware compatibility issues or just a matter of choice. Follow this guide if you want to remove Windows 10 from your dual-boot configuration and switch back to Windows 8.1
Uninstall Windows 10 Entirely from Dual-Boot
I removed Windows 10 from my system just because I decided to switch to Windows 10 entirely and hence upgrade Windows 8.1 to 10 instead of keeping a dual-boot and giving precious hard drive storage to both the OSes. Here’s how I achieved that:
a.) Removing Windows 10 from Boot Sequence
- Boot into Windows 8.1
- On the Start Screen, type msconfig.exe and hit enter
- On the Boot tab, highlight Windows Technical Preview or Windows 10
- Click on Delete
- That’s it. Press OK to close System Configuration window.
b.) Removing Windows 10 Partition and Files
- Open Disk Manager by typing diskmgmt.msc on Start and hitting enter.
- Right click on the drive/partition to which you installed Windows 10. It’s recommended to check the drive letter once again via the Windows Explorer.
- Choose Delete volume.
Alternatively, you can also choose to only Format or individually delete the Windows 10 directories via the Windows Explorer.
- Create a new partition over the free space that is generated and you’re good to go.
