Hi Mukund, Thank you for posting your question in the Microsoft Community. Sorry to know that you are facing this issue. Microsoft Xbox 360 Wireless Controller For Windows 10 Driver. As per the system requirement for Windows 10 installation, you need a minimum of 16 GB free space for 32-bit OS and 20 GB free space for 64-bit OS. As you have only 5 GB free space, you need to get another internal drive with more storage capacity on the computer. Once this is done then you can install Windows 8.1 on the new drive and later upgrade that to Windows 10. By doing this you would have a dual boot of Windows 8.1 and Windows 10.
Once you have upgraded to Windows 10 then on that drive you can perform a clean install of Windows 10 also. Keep us informed to help you further. Asus M4a89gtd Pro Usb3 Drivers Windows 10 there.
