EFI is great. I'd not realized that you dual-boot with the EFI bootloader, not with EasyBCD, boot.ini files, or the other stuff I'd used over the years. I did have to delete some fonts to clear out a little space in the /boot/efi partition, but worse things happen at sea, you know. I'm really pleased how easy it was. Hit ESC when booting and one-time boot your OS. Beautiful.
