This looks interesting, and I am tempted to walk into the deep water. It raises some questions.
Will gummiboot or refind also find the Ubuntu partition?
You should use the ESP (EFI system partition) to store all of the kernels. The loader (gummiboot) will find the Windows loader along with any kernels on that partition. You really aren't going to want separate boot partitions.
The original partition structure of the machine there were four or five partitions, and another one popped up in the higher end of the disk. I stumbled into the install, with the Ubuntu installer, and ended up with four linux partitions in addition to the Windoze partitions. At some point I used gparted to resize, and this might have been the step that botched the structure. But in any event, I have three Linux partitions of 50G each, and a swap partition. Ubuntu is sitting in one of those partitions.
I have no idea what is an EFI partition. I have seen instructions, presumably for those who are wiping the Windows and starting from scratch, to make an EFI partition.
I finally realized why there are so many partitions, and learned to use gdisk when walking through the Archlinux install.
Here is a some information from the gdisk listing:
Nbr Size Code Name -----+------------+------+------------------------- 1 1000.0 MiB 2700 2 260.0 MiB EF00 EFI system partition 3 128.0 MiB 0C01 Microsoft reserved part 4 49.6 GiB 0700 Basic data partition 5 9.7 GiB 2700 Lenovo (?recovery?) 6 10.0 GiB 8200 Linux SWAP 7 49.4 GiB 8300 Archlinux / 8 58.8 GiB 8300 /home 9 1024.0 KiB EF02 "bios_grub" (Ubuntu?) 10 59.8 GiB 8300 UBUNTU /
It's the one marked EFI system partition (ESP).
