Can not install i3 21.2.3

I have a i7 with a rx 6600 card 2 2tb ssd and a 10th springing disk . I’m trying to install the i3 spin But when I try to install it I make a 300mg /boot/efi with flag boot and the rest as / the the 2nd ssd . I set it as /home but after I install and reboot . I get error can not load lightdm

what ?!

I think you are confusing the partition assignment.

ok I did the same partition with the manjaro kde it works just fine 300mg partition set to fat32 set as boot/efi flag boot the main partition is set as / and the 2nd ssd the whole partition is set to /home
