Hi everyone first time question asker so forgive me if I make some mistakes but
Awhile ago I downloaded windows 10 and it ended messing up my hard drives and various other things (I'm sure some of you know what I'm talking about) but I've finally fixed all of that myself
But when I turn on my pc and enter my bios it doesn't detect my hard drive so it orders me to reboot after "installing proper booting device" but when I hit the RST_SW button directly on my mother board and let it reboot the bios and don't enter the bios it correctly boots windows, why will it not detect the hdd without having that button pressed? Should I be concerned? Please any input
