I did a a clean install on a new SSD drive. The computer takes around 3-5 minutes to get past the initial splash screen which asks " press delete to enter EFI settings in boot menu" or something. The computer does not respond to pressing delete at this time. after a few minutes the screen goes blank then shows the same exact same screen but this time it only lasts for a few seconds, it then goes through its normal boot sequence and the computer operates normally. This happens every time I restart my computer and it also occurs during and after I do clean installs on other hard drives. My computer did also show a CPU temperature error after this screen but I reapplied the thermal compound and installed a massive heat sink and now THAT problem does not occur but the ridiculously long boot time still does.
