I have got an Asus P10S-M WS motherboard, a Intel i7-6700 CPU, a SSD with Ubuntu 18.04 installed and a 8GB DDR4 ram stick.
When i try to boot it from the SSD it takes a long time to load the login screen (about 2min). Also, when I try to load a live USB its more of the same, it takes ages to load. Once its loaded it works really quick, so i dont think theres a problem with the SSD.
I have already checked all the connections to the motherboard, updated the BIOS to the last version, changed SSD sata cable, changed the sata port in the motherboard. I also tried a different RAM stick and nothing changed. The motherboard doesnt detect any failures on boot, but this isnt normal.
Hope some one can help me with this because i dont know what else to try.
