I have created the USB bootable linux on an flash drive. But when I start it up it keeps asking me to install Linux. Would installing linux install it on my desktop. Is there a way to run linux off of the flash drive so that it won't affect my current operating system?

This question was marked as an exact duplicate of an existing question.

Which Ubuntu release are you using, and how did you create the USB? – Mitch Sep 2 '13 at 7:09

In all likelihood you have created an install USB, not a bootable system. To create a bootable Ubuntu flash drive follow this tutorial.

I believe you have not created the live usb properly. You need to create the live USB again.

I belive you are using Ubuntu 12.04 run the following commands in terminal to install unetbootin

sudo add-apt-repository ppa:gezakovacs/ppa
sudo apt-get update
sudo apt-get install unetbootin

After installing unetbootin

This is how the GUI will look like


Or if you are using Windows I suggest you use USB installer provided at
