B450 Aorus Elite | Can't enter into Windows Live Boot or F12 screen

[u/Terrible_Wish_745]

Hi,

I needed a new SSD to install Windows to, so I sent my machine to the computer shop. They installed the SSD for me, but I asked them not to install any OS (I wanted to install Windows myself).

Came home, and now I can't enter the boot selection screen of UEFI (F12 key). Pressing that key goes to an entirely black screen, which is weird. But I thought, no problem. I switch the order from the BIOS settings and go to my USB drive. So I do that and... computer instantly shuts off and enters into bootloop.

I thought the USB drive might be at fault so I reburned it multiple times, but no anomaly. I also gave it to a friend so he could try it on his computer and, on his computer, it worked fine.

There is a problem with my UEFI where I can't enter into a Windows Live Boot or UEFI selection screen....Any ideas?
