This question already has an answer here:
I have downloaded the Ubuntu 13.04 ISO and I wrote it on a USB flash using USB startup disk creator. I reboot my laptop, went to the BIOS and I chose to boot my laptop from the USB and I saved the changes.
After that a black screen appeared. I don't know what to do. Please tell me what to do to make it work.
Also, when I connect my USB on Ubuntu, Ubuntu doesn't show my USB drive on the desktop and does not even acknowledge it. I really want to install Ubuntu 13.04 on my laptop because I am running Ubuntu 9.04 and it has many problems.
