Manual setup of UEFI, GPT and GRUB2

I recently got a Crucial m4.  I then have to transfer my existing HDD on it.  Its easier to do a clean install of Oneiric and it would pretty much do UEFI + GPT + GRUB2 for you.  However if you want to manually transfer everything I did the following steps:

• Boot on Oneiric live CD or another boot this that will boot in UEFI mode. Its important that boot is on UEFI mode and not BIOS mode
• Go to a shell and install gdisk as we want to partition the SSD w/ GPT and not MBR. fdisk only supports MBR

  apt-get install gdisk
  

• Partition a EFI system partition.  This would hold grub2 files later and other boot loaders if needed.  I partitioned mine on sda1 as type EF00 (EFI System) w/ the size of 200mb.  Yes a bit bigger than what is needed however most people recommend 200mb as some boot loaders needs a bigger space.
• Format the partitions.  The EFI System partition is formatted as vfat, as per EFI spec.

  mkfs.vat /dev/sda1
  mkswap /dev/sda2
  mkfs.ext4 -E stripe-width=128 /dev/sda3
  mkfs.ext4 -E stripe-width=128 /dev/sda4
  

  I put in a stripe width of 128 k as there are some recommendation this is optimal for SSD. However test suggest that your mileage may vary.
• Mount and create the dirs on EFI system partition

  mkdir /boot/efi
  mount /dev/sda1 /boot/efi
  mkdir -p /boot/efi/efi

• Install grub efi

  apt-get install grub-efi-amd64
  

• Setup grub on the EFI system partition

  modprobe dm-mod
  grub-install --boot-directory=/boot/efi/efi --bootloader-id=GRUB2 --no-floppy --recheck
  cp /usr/share/grub/unicode.pf2 /boot/efi/efi/grub/
  cp /boot/grub/grub.cfg /boot/efi/efi/grub/grub.cfg
  

  I copied my old grub.cfg and update the UUID to point to the new SSD
• Setup the EFI boot entry

  modprobe efivars
  efibootmgr --create --gpt --disk /dev/sda --part 1 --write-signature --label "GRUB2" --loader "\\EFI\\grub\\grub.efi"
  

  GRUB2 is the entry that would appear on the EFI bootloader.

The following resource helped me a lot

I am still working out on the graphics output,  This would only give you a text based grub.
