I was trying to install kubuntu 15.10 with the official image(downloaded from kubuntu.org) from live-usb, created with usb-creator-kde.
The notebook had already installed windows 8 in uefi mode.
I identified 100mb /dev/sda2 partition with fat as the bootloader partition, and was expecting to see something resembling this picture from tutorial
However, the "type" field of /dev/sda2 was fat32 and there was no option "efi" if I tried to change it, only "reserved bios partition", ext2, ext3, ext4, ntfs and so forth.
I also was worried by the fact that ubuntu have not recognized existing windows installation, usually it provides option of "installing alongside windows"
As I understand, this happened because I logged in with legacy live-usb kubuntu mode rather than uefi, however I don't see any other option during startup and if I try to manually add "uefi" option to the start command parameters I get kernel panic.
What is the proper way to make live-usb with ubuntu for uefi computer?
