Regrettably Kubuntu 13.10 has problems configuring UEFI correctly, such that you will not be presented with a bootable system after installation [1].
To rectify the problem an update has been released and all bootable systems should automatically get repaired during the update process.
To prevent this issue from appearing on newly installed systems please make sure the computer is connected to the internet and enable the option "Download updates while installing" on the "Prepare" page of the installer [2].
If no internet connection is available you can attempt a manual workaround that requires you to know how to use the terminal and mount command. Each UEFI system has a specific partition (formatted using the FAT filesystem) that contains the bootloaders. First you will have to find your system's EFI partition. It's usually best to simply mount all available partitions and check which one is the right one. The EFI partition will be rather small (only a couple hundred megabytes) and contain a folder called "EFI". Once you have found the EFI partition, copy the folder "EFI/kubuntu/" to "EFI/ubuntu/". That's all. After you booted into Kubuntu 13.10 it is advised to do a full upgrade as soon as possible.
Meanwhile additional quality assurance measures have been introduced to ensure that future releases provide the best possible experience on UEFI/SecureBoot systems, starting with 14.04.
