BIOS is on AHCI
CMOS rest already done
only funny thing - by default "Fast boot" option is "not activated" and normal boot would be like 30 sec boot time
i tried also to set on "activate fast boot" - nothing happend
when i turned on "Ultra Fast boot" 1 out of 3 times it fires up the system within 7-8 sec (really ultra fast :-))
but that does not work all the time - i will try in a different system and see what the SSD does there - if that works fine - if not --> on WE i will reinstall Win 10 - maybe a electrical instability caused just some files to get corrupted (which i do not really believe as it is no HDD - should normally not happen on SSD's - but lets see)
any other suggestions?
