I just installed ubuntu 13.10 on my Toshiba satellite s855d-s15120, and I have a 74mb efi partition, 75mb biosgrub partition, 30gb / partition, 8gb swap partition, and 712gb /home partition. boot loader is on /dev/sda1 efi. after I install it dumps me to "grub>"

any suggestions?

Usually better to have a larger efi partition, but that may work. And a bios_grub partition only needs to be 1MB unformatted space. But you only need efi partition if booting in UEFI mode and bios_grub if booting in BIOS mode. But normally not both.

Ubuntu will boot in either mode from gpt partitioned drive. And how it installs is based on how you boot install media.
