I have been using Ubuntu since Ubuntu 11.10 came out. I was very satisfied with how Ubuntu has evolved over the past few years, but now I would like to try out Fedora 17 since that has been out for a while simply for a change. I first had Windows 7 and Ubuntu on a dual boot; however, I got rid of the dual boot and installed Ubuntu 12.04 (32-bit recommendation) from a CD as my primary operating system. My problem is, now that Ubuntu 12.04 LTS is my primary operating system, how can I install Fedora 17 in its place?
I downloaded the Fedora 17 iso file (64-bit) and installed it on both a CD and USB, but I cannot get it to run from either. I investigated the problem and tried going into my BIOS by pressing f2 to make the USB the primary boot; however, this didn't work either. When I put the USB first in boot order, I receive a message that states "bootmgr is missing, press ctl+alt+del to restart". I've searched all over the internet in hopes of figuring out a way to fix this, but to no avail. Also, I have tried pressing f12 to pick the CD to boot from, but this option is nonexistent (I remember when I had Windows 7 that it was an option though).
I'm working with a Lenovo Ideapad Z560. I want to remove Ubuntu 12.04 LTS from my laptop completely and replace it with Fedora 17; I do not want a dual boot of Fedora and Ubuntu.
