So I'm trying to install ubuntu on my windows 8 pc. I want to completely remove windows 8, so disabled security boot, enabled legacy boot, and tried to boot the Liniux ISO right from my USB.

I changed the primary boot from my c: drive to USB. So when I restarted the computer, it tries to boot from USB but just says "operating system not found".

So I need to know how can I boot from my C: drive again?
