I am having this issue on a z97-a. Stays on 'Press del or f2 for bios settings' indefinitely and can't access bios settings, boot order led is on.
Fixes it by unplugging all sata ports and plugging back in (as mentioned here), except for me it is happening randomly when the pc is rebooted...
Any ideas for a better solution?
I had a similar issue on start up and the times I waited 20min for start up, at shut down. Come to find out windows identified my printer as a bootable drive and for some reason took priority over my ssd with OS. Simply had to reboot without peripherals connected and it starts beautifully. During the early stages of troubleshooting I found one of the hard drive cables not disconnected but not fully latched either. Take your time to check everything that should be in place is fully in place, clipped and clicked, and then, remove all unnessisary peripherals and attempt boot.
