Well, there's this which was the first result in a search for me. I would also make sure that you've allocated at least 500mb to a uefi boot partition, depending on what you meant by "old". I have found that sometimes there's a "secure boot" bootloader and one that just has the distro, but it doesn't mean the one you expect it to be will work. When you boot up at first I would mash the boot options key and see what shows up, if there's multiple options try them one by one. I suspect there's a boot setting in your BIOS that's not letting it boot properly.

I'd recommend trying to figure out what doesn't work right between install and liveUSB. 95% of the time in my experience that's due to non-free packages being available on the liveUSB, but not being enabled during or after install. If your issues are related to a specific component (Wi-Fi, graphics, etc.) then it's probably something that needs third-party or non-free sources enabled.
There's some sort of deal where a distro can't just install non-free drivers due to licensing without you agreeing to use them, so they add a question or option to enable those during install in order to use them. They can have them enabled in the live USB for some reason. You can also do that after install by poking around in your repository selection.
These are pretty simple things to investigate once you're used to using Linux, but certainly a bit overwhelming for someone new.
What distro are you trying out and what are the issues you're seeing between preview on USB vs install?
Go for it. You don't need to install Linux in order to start getting your feet wet. Get a USB 3.0+ flash drive and put a "live" (CD/USB, whatever the distro wants to call it) distro on there. There are plenty of directions out there on how to make one from Windows. Most live distros nowadays are persistent, so any programs you install will be there next time you load it up. It will definitely be slower than a normal install, but it'll let you get a feel for how things work.
Go ham wild on there, break stuff, see if you can fix it, don't, then remake it again. Try different desktop environments (DEs) and see what you like. Your distro of choice is less important if you're just starting, but any of the big ones will be fine. I'd recommend trying a few different DEs from the same distro, see what you like the feel of, then try a different distro with what you liked best. They'll usually all have gnome, kde, and a third lightweight option, but in my experience if Wayland (the other choice is X11) works well, kde and gnome will feel pretty light. I use kde Wayland on this guy and trust me, this review is giving it a lot of grace. Windows 10 was completely unacceptable on it, so if your specs are any better then this, you'll be fine with whatever you choose. Beware that Nvidia cards have driver issues, they're fixable but if you do have an Nvidia card, I'd just use the built in graphics chip for trying out Linux at first.
Don't start with arch, btw.
Sure you could. But I'll offer a different perspective
All honey tastes different from different producers and areas, you'll be missing out on some wonderful honey flavors if you buy that much in bulk. If it's purely for sweetening, sure fine, do it. But if you want the flavor of honey, check out a farmers market and see what you'd be missing out on with bulk.
I want to know how much I have to work.
To neurotypicals this sounds like you don't want to put in the work. A better way to phrase it would be "I'm just trying to see how busy today will be" you can follow it with bullshit like "trying to decide if I'll be cooking dinner or picking something up on my way home"
What's your point?
