G'day jb & Welcome to Linus.org
1.
yone have any tips on temporarily installing a Linux OS on a USB disk key to "try it out"?
First, you can -- __and should__ -- try Linux Mint before switching to it. Fortunately, unlike other operating systems, Linux distros like Mint make it easy to give them a test run before installing it.
First you'll need to download a copy of Linux Mint, which comes with three different desktops: MATE, Xfce, and its default desktop, Cinnamon. If you have a 2012-or-newer PC, I recommend you download the 64-bit version of Mint with Cinnamon and multi-media support.
If you don't have an __ISO burner program__, download one. I recommend freeware programs ImgBurn for optical drives and Yumi for Windows for USB sticks. Other good choices are LinuxLive USB Creator and UNetbootin. These are also free programs.
**UPDATE.**....use [[https://www.balena.io/etcher/|Balena Etcher]] ....Also Free
**Giving Mint a try**
Once you've installed the burner program and have the latest Linux Mint ISO file in hand, use the burner to put the ISO image to your disc or USB stick. If you're using a DVD -- __Mint is too big to fit on a CD__ -- check your newly burned disc for errors. Over the years, I've had more __problems with running Linux and installing Linux from DVDs__ from bad discs than all other causes combined.
You can set it up a USB stick with persistent storage. With this, you can store your programs and files on the stick. This way you can carry Linux and use it as a walk-around operating system for hotel, conference, and library PCs. I've found this to be very handy and there's always at least one Linux stick in my laptop bag.
**Next, you place your disc or USB stick into your PC and reboot**. During the reboot, stop the boot-up process and get to your PC's UEFI or BIOS settings. How you do this varies according to the system.
Look for a message as the machine starts up that tells which key or keys you'll need to press in order to get to the BIOS or UEFI. Likely candidates are a function key or the "esc" or "delete" keys. __If you don't spot it the first time, don't worry about it. Just reboot and try again.__
Once you get to the BIOS or UEFI, look for a menu choice labeled "Boot," "Boot Options," or "Boot Order." If you don't see anything with the word "boot" in it, check other menu options such as "Advanced Options," "Advanced BIOS Features," or "Other Options." Once you find it, set the boot order so that instead of booting from the hard drive first, you boot from either the CD/DVD drive or from your USB drive.
Once your PC is set to try to boot first from the alternative drive, insert your DVD or USB stick and reboot. __Then, select "Start Linux Mint" from the first menu. And, from there, you'll be running Linux Mint.__
Some Nvidia graphics cards don't work well with Mint's open-source driver. If Linux Mint freezes during boot, use the "nomodeset" boot option. You set this to the Start Linux Mint option and press __'e'__ to modify the boot options. Then, replace "quiet splash" with "nomodeset" and press F10 to boot. On older PCs using BIOS, press 'tab' instead of 'e.'
__MINT WILL RUN SLOWER THIS WAY, BUT IT WILL BOOT AND RUN__. If you decide to install Mint, you can permanently fix the problem with the following steps:
Run the Driver Manager
Choose the NVIDIA drivers and wait for them to be installed
Reboot the computer
SO **FAR YOU HAVEN'T INSTALLED ANYTHING ON YOUR PC, BUT YOU WILL BE RUNNING LINUX MINT. USE THIS OPPORTUNITY TO PLAY WITH IT TO SEE IF YOU LIKE IT..**
Using a DVD drive Mint will run slowly, but it will run quickly enough to give you an idea of what it's like to use Mint. With a USB stick, it runs fast enough to give you a good notion of what working with Mint is like.
PLEASE...play with it...explore everywhere....you CANNOT break it...remember it is on a thumb drive....if it goes up in smoke, just reboot and away you go again. No harm done.

2. Partitioning....either during installation.......do you have a backup of the material you wish to keep ??
3. My immediate reaction to that question is always Linux Mint
or have read of the following...
