Power on, and start spamming the delete key immediately as soon as you power on, and keep spamming the delete (Or F2, whichever gets you into the BIOS on your board) key until you see it enter the BIOS.
If that won't work, then you'll likely need to clear the CMOS. Sometimes Ultra fast with an SSD is simply too fast to get past. On most my Gigabyte and ASRock boards that have had Ultra fast boot I have been able to get into the BIOS though by rapid fire spamming the key right away until I see it enter the BIOS.
