I'm attempting to switch from Windows 10 to Pop OS, but I'm running into a roadblock. My computer displays a message saying, "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system" whenever I try to boot from the USB setup. Should I unplug all the drives that don't have an OS on them, or is my USB drive possibly faulty?

If you're still having trouble, consider using Ventoy. It's a simple tool that can help you manage multiple bootable USB drives easily. You can find it at their website.
When you're booting up, if you press the boot menu key (often F12 or Del), you should be able to select the USB as the boot device. Just make sure you’re selecting it correctly!
First off, how did you prepare your USB drive? Simply dragging the .iso file onto it won't work. You need to use a tool like Rufus or Balena Etcher to properly create a bootable USB. Also, make sure you're entering the boot menu using F8 or F12 when you start your PC!

I did try that, but I still get the same error after selecting the USB.
