The GUI is intuitive. It boots initially into an OS with a bunch of useful tools. The disk cloning software is straightforward and it works perfectly - I can vouch for this since I’ve had to resort to it on a couple of occasions restoring my system from the back up images. It’s also not complicated like Clonezilla.

Foxclone every time. Excellent piece of kit.

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.
