Solved! The Lenovo keyboard does not seem compatible with the BIOS and some Ports during boot. I tried a borrowed Dell keyboard and everything is fine on all ports. All is Good! Thanks for your help!
I completely reset my Inspiron 9470 to factory setup, and after all of the Windows updates everything seemed fine. I then saw that the Dell updater recommended updating several things including the bios, so I I did. There seemed to be a problem updating, as it took a long time and "transferred 3 updates repeatedly over and over, finally doing the flash. When the system tried to reboot, it was stuck in the pre-boot system performance check. I tried recovering back to the previous Bios without success , I tried reinstalling the updated bios, and still no luck. During the flashback, there was some error with "ME" but when I returned to the updated flash, there were no errors. I tried all of the suggestions including disabling secure boot, and several other bios settings to no avail. The only way I can use this system is to hit F12 like a madman and boot from either the boot manager, or the hard drive partition directly. I'm really upset with dell at the moment. The system is only a few years old, and this shouldn't happen.
