Installing 22.04 on mac OSX does not propose Dual Boot option

[Michel-Ekimia]

Imac 8,1 with Mac OSX 10.11 with journal disable on HFS+ system partition :

Booted on Pure EFI ( No Bootcamp nor Refind )

Ubuntu 22.04 installer would propose only :

- erase all the disk and install
- Something else

it should propose like on a windows EFI machine

- Install along OSX ( I even prepared 120 GB free on the disk for that )

Although the manual installation detects the EFI partition and adds the Ubuntu bits
