As I said in an earlier email, there's no MBR when you use UEFI.

UEFI has an integrated boot manager that can be accessed at boot in
the same way that firmware's accessed on a BIOS system.

The UEFI boot manager allows you to choose a file to boot from on the
"EFI System Partition", "\EFI\...", which is a FAT partition that's
mounted at "/boot/efi" on Linux. The files that the boot manager loads
are in "/boot/efi/EFI/boot/", "/boot/efi/EFI/Microsoft/",
"/boot/efi/EFI/ubuntu/"...

You can add/remove boot manager entries or define a default one with
bootcfg on Windows and efibootmgr on Linux.

For me, with both the 12.10 and 13.04 installers, the boot manager
defaulted to Ubuntu's grub. I've forgotten whether Windows was
automatically available in the grub menu or whether I had to add it.
