Fail to install ubuntu by custom partitions

[Akronix]

I don't know if I did right or what's the problem.

I created 4 partitions in the following order:
-512MB for EFI boot
-150GB for /home in ext4
-41.5GB for / in ext4
-8GB for swap

When ubuntu installer was setting up the GRUB, it got an error and abort the installation.
