Type n to add a new partition and +500M to give the bootloader a size. You now need to delete the entire partition table on the disk to be able to set up a new GPT partitioning:

You don't want to convert your MBR partitions to GPT format! THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by typing 'q' if The initial output is a warning if the disk is not a new disk or a disk already using GPT: GPT fdisk (gdisk) version 0.8.8 However 'Gparted - gparted' along with 'KDE Partition Manager - partitionmanager', (amongst others), are great tools to give you a visual depiction of what you actioned in gdisk.įor example, assume that it is /dev/sda and start gdisk with the path to disk: sudo -i Having stated that, gdisk should be your preferred tool to help prevent unintentional GUI anomalies. GUI tools like 'gparted' and 'partitionmanager' do provide a GUI interface supporting GPT disks. The EFI System partition will also be mounted as /boot/efi as long as you leave the "mount other partitions" option selected, you do not need to tell the installer to mount this partition. If you are going to boot using EFI you must have a FAT formatted EFI System Partition (type EF00 ) as the first partition.

Unfortunately, there was only a message Reboot and select proper Boot device or Insert Boot Media in selected Boot device and press key When the installation was finished, I rebooted my laptop. For now, the SSD is empty and I chose the HDD as bootable device during the installation.
On my Toshiba, Satellite E45T Ultrabook I have made a backup of my Windows 8 recovery partition then I booted a Live USB with Ubuntu, cleaned everything on my HDD (750GB) and SSD (32GB) and installed a fresh Ubuntu 14.04 with an UEFI partition.
