Try LXLE. I stuck it on an old 16+ year old desktop and it runs smoothly as my shed computer.

I miss all the crashes, the blue screen of death, the automatic updates that reconfigure all the personal changes you made to try make Windows work better, and all the hunting around for cracked propietary software.

Like already mentioned here, back up first. I use a tool called Foxclone for hard drive image backups. Many would recommend Clonezilla, but I can vouch for Foxclone as I know it works from personal experience and the interface is really intuitive.

If you installed your Linux distro to dual boot alongside an existing Windows machine, you might need to move the Linux partitions after deleting Windows in order to resize the Linux partitions. This is something that can be done later once you know everything is working okay.

I find the UI pretty slick. No confusion over what needs to be done. All the tools are there plus I had to rely on it recently to get one of my machines back up and running. It worked flawlessly and restored everything from the backup images like my system had never been down.

Try Foxclone. I prefer it over Clonezilla.

So glad I recently removed Windows from my former dual boot system completely. Was sick of getting errors during Linux boot up after running Windows for that one piece of software I couldn’t get to work in Wine or Bottles. The culprit I assumed was Windows updates, which I attempted to disable through the registry on several occasions. It would work for a short period and then Microsoft, in all their wisdom, would just reenable updates because clearly they know better than I what I want my system to do. The last time it happened was the final straw for me when I wanted to boot into Windows briefly only to be left waiting half an hour for Windows to apply updates on shutdown. Pissed me off so much I killed the power mid-update, booted up a live partition tool and wiped Windows off my system completely (updating the grub to remove dual boot). That’s when I discovered that not properly shutting down Windows would mark my other drives dirty and make them read only. To fix this I ended up having to insert Windows installation media and pretend like I wanted to reinstall Windows 10 again. Once it got to the stage when it was about to write to the drive I cancelled the installation and rebooted back into Linux. Voilà! Could write to my drives again. To hell with Windows. I’d rather live without that one piece of software and have my system do what I want it to do rather than it second guess me and disregard my instructions. This whole automatic update thing really boiled my piss. At least with Linux I can choose to apply updates when it’s convenient for me to do so.
