Lenovo Z570 If you create a /boot/efi partition (Fat32) first Ubuntu 18.04 installs BUT you cannot boot Windows 7 which is install legacy/bios boot. The only way I could solve it was to delete all the partitions and reinstall Windows 7 in UEFI boot mode. Then you can install 18.04 and boot either OS at startup. Of course you have to keep all your data somewhere else. I got the computer second hand so I didn't have any apps or data on it.
