I recently installed a new Intel MB for a customer. Along with a new processor, new memory and fan. Used old HDD. He has 2 Hard drives. Now when I try to boot, it gives me the boot options screen. I pick use last settings that work and it just goes back to boot menu screen again. Same thing if i pick safe mode or start normally. I checked the bios and it is detecting the HDD and set to boot to it. I do not have the CD or FDD hooked up.
