Help please! i’m not really a tech savvy person so i’m sorry if this is something simple but i’ve been having problems with my cpu lately we’re i start it up and it says “no bootable devices found”. I looked over the internet and found many things similar but nothing that actually helps, I’ve checked my bios settings and my hard drive shows there but in my boot sequence it doesn’t show. It also doesn’t allow me to switch form UEFI or legacy mode, i’m very confused about this whole ordeal
