Interesting new boot issue,
Built the new system yesterday:
Z270 FTW K
I5 7600 K
16 Gig Corsair Vengeance 3400
Drive 1 WD 256G M2 in slot 2
Drive 2 260g Samsung SSD
Drive 3 1T IDE
Drive 4 2T IDE
I was able to set Drive 1 to boot drive in the bios without issue and was able to boot to that drive. Every time I boot the system displays on black screen in large text, no boot media press any key. I reset the PC and hit F2 to check bios and the 1st boot drive is drive 1. Click save and exit, save changes and restart, the system boots great. Once I do a restart from windows back to the black screen and and F2 process again.
Any thoughts on this?
