This - but I’d take it a step further and use a small-ish USB 3.2 SSD with Ventoy instead. That way, your live Linux experience isn’t kneecapped by having to load programs off a slow USB stick. In a pinch you can use a SATA SSD with a USB-SATA adapter too, that way you can cram a ton of ISOs on there and go to town.
I use VBox to run my PiHole for now and have used it to play with a couple distros side by side. I also have a sup’d up tower built from spare parts from work, so resources aren’t a constraint.
My preference is „bare metal” approach, then I really know if everything is working as it should, so I had a separate drive for Linux installation at the beginning and got to my other drives by just mounting them as NTFS.
But, finally I am at the point of no return for some time now, the old Windows drive is not even inside of my PC and the other drives are ext4 already.
For a quick check Live CDs/USBs are totally fine but not fully representative.
This is what I did, and it did its goal in making me comfortable using Linux. However, like what others suggest, live USB is probably much more easier honestly.
