I am trying to install Ubuntu 14.04 LTS on a UEFI system that already has Windows 7 installed. Windows is installed on the first SATA disk (sda). I want to install Ubuntu on the second SATA disk (sdb), which is currently empty.
I have a reasonably good understanding of how UEFI booting works. I envisage that I need to do the following:
- Manually partition the second disk using the "Something else" Installation Type, creating a ~250MB ext2 partition for /boot (sdb1) and the rest of the disk as an LVM PV partition (sdb2). Then create root and swap LVs.
- Mount the EFI partition on the first disk (sda1) under /boot/efi, so that the installer can put the Ubuntu UEFI loader files alongside the Windows ones.
I am having two problems though.
- When I try to partition the second disk, I am unable to create an LVM PV partition. That type isn't listed in the "Use as:" dropdown menu.
- There doesn't seem to be any way to mount the EFI partition from the first disk (sda1) under /boot/efi.
Has anyone else worked out how to get around these problems?
