Okay, so ill cut this short. I had switched from Windows 10 to elementaryOS because windows had gotten laggy. After switching, i realized there weren't a lot of games and couldn't use Wine so Ubuntu was my option. I installed Ubuntu on a USB with UNetbootin and tried to boot the USB drive. And the roadblock. When i manually booted via boot menu, the computer jumps right in to elementaryOS. I'm just looking for a solution to this problem.
First, don't use unetbootin unless a distro specifically requests it. On Linux, your best bet is to just use DD (google how to do it with an iso), or use gnome disk utility (google it as well), or BalenaEtcher. On Windows, use Rufus, or again, use whatever method the install guide for the Distro recommends.
Secondly, Elementary is based on Ubuntu LTS. Anything that works on Ubuntu, works on eOS (usually except the occasional bugs). I've personally had no issues installing Wine, Lutris, and Steam on eOS. Both Lutris and Wine has install guides how to do it.
Seems you're problem is about the boot media, not about elementary.
Don't use UNetbootin, which usually fails. Use Etcher which usually is better.
Either way, elementaryOS is based on Ubuntu, so if anything runs on Ubuntu it runs on elementary. I use elementaryOS and play a lot of games in Steam via Proton (a utility developed by Valve to run games via Wine) and I'm very happy.
I'll echo babel's comments. I haven't found anything in a debian or ubuntu package that doesn't install in elementary. I think wine is even in the App Center.
That being said, I did a lot of distro hopping before settling on elementary OS and I often find that nothing will work. Just a few days ago I had to wipe a drive that had OpenSUSE on it to install elementary OS. It SHOULD have worked by booting from the USB, but it didn't despite all the fiddling around with the BIOS. I've found this on all kinds of distros. I've had the same USB work on one computer and not another.
In short, and assuming you have exhausted the options in your BIOS, wipe the destination drive and try again.
