All computers in this explanation are Intel based 32-bit machines. I first tried to upgrade via internet thus: Using Firefox browser on a Fedora10 machine, when I try to access , I receive "Secure Connection failed-Unable to generate public/pair key". The Firefox version is old-3.0.15. I have been unable to upgrade to new version of Firefox--I believe because Fedora10 reached EOL long ago. So I went to Windows 7 computer, downloaded and burned to a RW DVD the file Fedora-Live-Workstation-i686-21-5.iso When I boot that DVD (on the target machine currently running Fedora10 in which I changed CMOS setup to boot only from the DVD), I get message "Unable to find system". Using Fedora10, I can open the Fedora21 DVD with the File Browser and the directories EFI, isolinux, LiveOS, GPL, and README are visible. I can also, on the Fedora10 machine, boot from my original Fedora10 DVD. Am I missing something on the Fedora21 DVD that allows it to boot? or what? Insightful comments are certainly welcome.

Given the huge span in version differences, you're way better off backing up and doing clean installs.

Imposible, red here: FedUp (FEDora UPgrader) is the official tool for upgrading Fedora installations. Anaconda, the Fedora installer, has no built-in upgrade functionality in Fedora 18 or later.

Have you used DVR-RW discs with this setup before? Some older drives couldn't read them well, especially if they've been used a lot. You might try alternative boot methods from - and I'd advise using the XFCE or LXDE spin; Gnome3, that comes with Workstation needs a newer computer to work comfortably.

Did you consider booting the Fedora Live System/Installer from a USB thumb drive? You could create a bootable USB drive using unetbootin under your Windows system. That should work. Make sure your computer BIOS is set to boot from USB attached devices.

I recommend doing a fresh install of Fedora 21 - there is no upgrade functionality from 10 to 21 (see comments above)

  1. Backup your system (all files in /home/user including hidden files and folders (CTRL+H))
  2. Download your iso image: (32bit)
  3. Make a bootable USB thumb drive (use UNetbootin)
  4. Change your BIOS setting in order to be able to boot from USB
  5. Start the Fedora Installer/Live system from the USB drive
  6. Create completely new partitions for F21 during install (you will need 10-15GB for the Fedora system, depending on what programs you want to install)

@randomuser has linked above which helps you install Fedora if NO USB or CD boot option is available on your PC
