For those who might not be familiar with it, Korora is based on Fedora, but with lots and lots (and lots) of additional packages included in the base installation. That makes it a particularly interesting distribution.
There are four ISO images available, for Gnome 3 and KDE desktops in 32-bit and 64-bit versions.
The images are large (1.6GB for Gnome, 2.2GB for KDE), but they are still hybrid ISO images, so you can dd them to a USB stick, or burn them to DVD media. They support both "normal" BIOS and UEFI BIOS, and Secure Boot.
On UEFI systems, there is one small quirk I've noticed: The directory where the EFI boot files are installed is still called "fedora", so in the unlikely event that you are installing Korora on a system where Fedora is already installed (or the other way around), they will overwrite each other unless you do something to prevent that.
The installation procedure is identical to installing Fedora 18, using anaconda, so check my previous post about installing Fedora 18 for complete details and screenshots of that.
Because of the large amount of software that is installed, the process takes about an hour, which is considerably longer than most other distributions. According to the release announcement, there were no significant problems reported with the last beta images, so the release images are in fact the same ones, simply renamed for the final version.
This has one side effect that you need to keep in mind: They really need the latest updates.
As soon as you have booted the installed system, the first thing to do is configure the network, and then get all the latest updates. There will be more than 600 updates to install, which will probably take another hour or so, but they are definitely worth it.
