Windows 10 is the latest operating system from Microsoft, possibly this will be the last version of windows.
Thanks to my mate Kevin for the beautiful background picture.
I have been using W10 now since July 30 2015 and there is nothing which is causing me any grief (yet). At first my download did not want to happen so I forced it manually. Have a look at how via this video.
Once I had the download I used the Media Creation Tool to create a bootable USB and I installed on a brand new disk.
You will need a 4G USB Stick to create the bootable device.
If you are going to use a drive bigger than 2Tbytes please visit UEFI Boot and GPT to assess the ebnefits of a GPT partition and UEFI boot.
