I had windows 7 running fine on a new thinkpad laptop for about a week. I recently tried to install Fedora. There were no problems with the installation from what I saw. When I rebooted after installation, I got a "Media Test Failure: check cable" error, and it gets stuck there.
Now I can't get into Windows or Fedora, because the startup gets stuck with this error whenever I turn it on. I tried playing with the boot order, but that didn't help. I also tried switch between UEFI and Legacy (although I have no idea what these things mean), but that didn't work either. The only thing that I can do is boot into the live version of Fedora via usb.
Could someone please help me out? It's frustrating being locked out of a new laptop.
