I just jumped over to Linux in June. I booted into the Debian Live USB with KDE Plasma as the desktop environment. In general, make sure you have an Ethernet connection available for the first install. I basically tried it out in the live environment for a few days and I fell in love with it, in particular KDE Plasma. I picked Debian because I prefer not to update my PC very often (or at all on my music production computer), plus I had a nice time with the Raspberry Pi, which uses a derivative of Debian. If I really need the absolute newest version of any specific software, I have no problem installing it from a .deb and I can usually compile from source if the project is decently documented, but if you absolutely do not want to do that, you might want to pick a different distro. Whatever distro you pick, you’ll be able to install KDE Plasma later. KDE had all the features I actually liked from Windows 10, but just better and more customizable. You can really make KDE work for almost any workflow.
I ended up installing it onto my music PC in a dual-boot configuration with my existing Windows 7 install. Unfortunately, I cannot afford to migrate my music production projects off Windows 7 because I was sloppy over the course of a decade with project directory structures and multiple drives, so I probably can’t move these projects to any OS until I put in a few weeks of work to actually organize all those files. Oh well; everything else can work with Linux.
I’ve gotten pretty far so far by just installing Wine and Proton and using my existing Windows programs through those compatibility layers.
I also dropped Debian onto my school/work laptop in a dual-boot configuration with Windows 10. Except for the background, which I decided to make different, KDE is almost indistinguishable from Windows 10 until I start to use it, which reminds me how much nicer KDE is to use.
Most distros have live USBs with easy installers that make the whole process really painless. I basically installed Debian in the background while watching TV (Invidious), all inside the live install.
I also put Debian with LXQT on the remains of my old highschool PC, basically just a motherboard with integrated graphics, RAM, CPU, and case; no hard drive, no external graphics. I just put Debian onto a microSD card [1] and told the BIOS to look there for bootable drives. No commitment. As much as I love KDE, it does require non-trivial resources to exist. Since that hardware is over a decade old now, I really can’t afford to give any of it to a desktop environment.
So if you really can’t commit to Linux, you can slap it onto a large microSD and tell your BIOS/UEFI to boot it. It’s a little slower than putting on a drive, but sufficient to give Linux an extended test-drive.
You could also try installing it in a virtual machine. Linux plays very nicely with Virtualbox. I picked LXQT for my old PC by installing a virtual machine with Debian and installing a bunch of desktop environments onto the system. Then, I cut back the number of cores, processor speed, and RAM available to see how they acted.
My point is, I really think it’s a good idea to try Linux now. It really will not take very long to get a great, usablr system, and you can make it yours by making little changes as you go along.
[1] Meaning, I used a live install USB to install to a separate microSD card. A live install loads the entire OS and any programs you install into RAM. In general, the content of the live USB isn’t changed, and it’s difficult to do so. What I did was to treat the microSD card as a hard drive and install a normal system.
