I would make a system Image of Windows 10 .
What would you do if you decided that you didn't like Linux ?
I might even suggest that you purchase a new Hard drive or Solid State Drive and keep Windows on the original Just In Case.
Just purchased a Lenovo Yoga 2 11 with Intel N3540 2.16G CPU, 4G RAM, 500GB HDD and Windows 10 Home OS. It is a nice little laptop. I like that it can be used as a laptop. It is a nice size, not too heavy, not too big, not too small ... But it is unbelievably S-L-0-W! I know that Windows is a beast using enormous amounts of resources. I'd like to Replace my Windows 10 OS with Linux Ubuntu. I understand that Ubuntu will be much faster, use fewer resources, and will not be too difficult to learn. My question is, how do I do this? I understand that I need to download the Linux OS with a boot file onto a disk (SD card in this case). Where can I acquire this file then how do I go about replacing Windows?
