HP OMEN ce018np issues - PinguyOS 18.04.1

I wished to give it a new try with the latest 18.04 version you have on SF.

The official specs are at https://support.hp.com/us-en/document/c05682497

1. This is a dual-boot system with MS Windows 10 and, hopefully, PinguyOS
2. On laptop I have the following partitioning:
   • EFI partition on SDD (where Windows has its EFI and where the /boot/EFI should be)
   • MS Windows 10 partition (C:)
   • /boot partition ext2 on SDD
   • /partition ext4 on SDD
   • MS Windows Users and data partition on HDD (D:)
   • MS Windows Recovery HDD (E:)
   • /home partition on HDD
   • /var partition on HDD
     

First, it can only boot if I choose noapic acpi=off on kernel loading
After that PinguyOS installed but...

1. On install the installer allowed me to define the EFI partition but didn't allowed me to set it as the place where /boot/EFI should be installed
2. On boot it won't boot at all. I had to go to BIOS to start it from Windows EFI
   

All other distros I tried have different issues but all allowed me to define /boot/EFi on the existing EFI partition

Using Boot Repair was not an option hence it destroyed the Windows boot and I had to recover it later.

How can I solve this?
