Ubuntu – When I start the Ubuntu ISO, initramfs says “unable to find a medium containing a live file system”

bootinitramfsuefiusb

When I start the Ubuntu ISO(13.10) on a USB, initramfs says "unable to find a medium containing a live file system".

These are my PC specs:

I have Windows 8.1(64 bit, with Update 1) installed on this computer.
Other computers that I tried with the same USB didn't give the error.

What I tried to fix this:

  • Switching from IDE to AHCI(I already did it before on this computer).
  • Using other USB ports.
  • Switching from USB 3.0 to 2.0(and backwards).
  • Switching from UEFI to Legacy(and backwards).

Nothing that I know works right now.
Are there any possible solutions?

Using Ubuntu 17.04 ISO on a SanDisk 32GB USB stick. My m/board is ASROCK B250M. None of the suggestions I read online worked for me. I noticed, though, that the USB stick was mounted when I pulled it out and plugged it back in, so when the installation was showing the Ubuntu 'wait' screen with flashing dots, I figured it was looking for the installation media, so I pulled out the USB stick and pushed it back in. Hey presto! - the installation media was found and I managed to install Ubuntu.
