I am using manual partitioning.
There is the need of an EFI partition to start the system.
I setup a 300 MB FAT32 at the beginning of the SSD.
The installer did not create the partition correctly.
After deleting and new-creating the EFI (FAT32) partition, the installation completed successfully and the system started.
The FAT32 partition was not setup as EFI partition and the installer could not detect the partition as EFI partition.
Did you set the boot flag on the partition in the installer?
I set the
boot flag during partitioning.
The only other boot flag is
I could not set the
esp flag, because it was not in the list (of flags).
