I am currently running dual-boot Windows 7 / Ubuntu 14.04 LTS on a 32-bit processor (1.66GHz dual, 2GB memory). I want to go pure Ubuntu. Which, if any, of the following options makes the most sense with the least amount of effort and/or chance for disaster:
1) reformat Windows partition to ext4 and use as a separate data partition,
2) delete Windows and repartition drive to a single partition, or
3) archive Ubuntu data and full format/clean install either 14.04 or 16.04?
If you have another option that makes more sense/takes less effort, please share. I am somewhat proficient with CLI, but by no means an expert.
Thank you.
