fail to install Grub. I have deleted the UEFI and Grub partitions due to boot problem UEFI

[Didier Misson]

Ubuntu 18.04 LTS refuse to boot due to UEFI file missing ?
18.04 was working before...
So, I reinstall new 18.04.01 LTS
I have delete UEFI and Grub partitions, thinking that these partitions will be create again
Place is available on HD Samsung SSD NVMe 500 GB...
But install failed : Ubuntu doesn't create UEFI and Grub partitions again ?

Thanks. Didier
