[SOLVED] ERROR: Unable to find root device

I installed an additional SSD for storage use (not for root) on my desktop and when I reboot I get this   ERROR: Unable to find root device '/dev/sdd3'
dev/sdd is my SSD for boot, swap, root and home.

The disks configuration on my machine without the new SSD:

lsblk -f

I'm using UEFI, gummiboot  and GTP on all partitions  BTRFS and fat on sdd and ext4 everywhere else. The motherboard is GIGABYTE GA-G87-DS3H.

I'm able to boot OK with the new SSD installed if the sda HDD is remove.
