When I created my Fedora 21 Live with imagewriter on windows and then boot to it, the graphics are horrible and you can't read anything on the screen. When I use the live image in virtualbox everything is just fine.

Fedora 20 does not have this issue.

Open up a terminal virtualbox and run this command: lspci | grep VGA and add the results to your question. That will tell us what type of graphics you have and help us troubleshoot this issue.

When I use the LIVE USB I can't read anything but managed to email the response

[liveuser@localhost ~]$ lspci | grep VGA 01:00.0 VGA compatible controller: NVIDIA Corporation GK104 [GeForce GTX 660 Ti] (rev a1)

I have no issues with any other linux distro or even Fedora 20 for that matter.

I have this trouble running on oracle virtualbox. I have used the keys Ctrl + Alt + F1..F7 for restore the video and sometimes i have used the startx command.

I see that you're using nVidia graphics, which is what I suspected. At boot, select the most recent kernel, but press E to edit the entry. Find the line that reads echo 'Loading initial ramdisk ...' put the cursor at the beginning of the line and use the left arrow to back up to the end of the preceding line. (It's a long line, and this is the easiest way to get there.) Add a space and a 3 to the end of the line, then follow the on-screen instructions to boot. This should get you to a text-only command line. Log in as root, and remember that you're root because things can get messy if you don't. Once you've done that, follow the instructions at the fedora forum for installing the appropriate kmod-nvidia. Don't worry about the thread's title, as it's just as appropriate now as it was when it was first written. Once you're done, you should be able to reboot and have proper graphics. (That edit you made, btw, was only a one-time change.) Good luck, and please keep us informed!
