Why aren't you using 13.04 directly?

Why aren't you using the installer's defaults rather than partitioning
manually? (At least as a test!)

Have you cleared the various boot entries that must be cluttering the
NVRAM by now either via the firmware or via efibootmgr?

Are you installing grub-pc or grub-efi?

Is the FakeRAID being managed via dmraid or mdraid? (AIUI dmraid is
deprecated or in the process of being deprecated.)

Have you tried installing to a non-FakeRAID RAID 0 array? (You can
create one manually from the Live CD.)

Does the EFI partition that you're creating have a FAT32 filesystem
and a EFI System Partition type ( (EF00?

What does "I've place the GRUB boot loader on VOLUME0" mean? Unlike on
a BIOS box, grub doesn't embed anything into an MBR or a post-MBR gap
or a "bios boot" partition (EF02). The EFI boot manager'll point to
grub on the EFI System Partition.
