GTP Partitioning of the DISK
UEFI Mandates this GTP partition table. GPARTED tool makes this partition happen.
http://gparted.org
http://en.wikipedia.org/wiki/GUID_Partition_Table
Download ISO burn to CD/USB. Boot up and setup the Partition below vi GPARTED Application.
Before doing the partition, you have to format the disk with GTP partition table via GPARTED.
400MB System Partition FAT32 as per the UEFI and GUID Partition Table Specifications. This has to be in the start of the disk. Make sure to set the BOOTABLE flag = true
250GB NTFS
30GB EXT4 for Linux root
4GB LINUX-SWAP
Apply/Commit all the changes to the disk.
BOOTING IN UEFI Mode
Most Important : Make sure to Boot the UBUNTU 13.04 CD in UEFI CD Boot mode. There shall be plain boot mode for the same CD. Careful in your selection.
More Info @ https://help.ubuntu.com/community/UEFI
Now boot up the UBUNTU 13.04 CD in UEFI mode.
400MB System partition has to be mapped to EFI PARTITION as File system during the UBUNTU installation. Rest of the Partition have be mapped for UBUNTU installation(ie root and swap).
After the installation and reboot,you shall see this layout below. GRUB2 is installed under EFI PARTITION which is mounted as /boot/efi
