im literally losing my mind here i ran the ECS E07EI1 Bios 08/10/23 BIOS/firmware update on my laptop cuz the support page said it improves stability, partway through, the screen stayed black. now when i press the power button, i get this:

Reboot and Select proper Boot device
or Insert Boot Media in selected Boot device and press a key
No bootable device -- insert boot disk and press any key
the fans spin, a light comes on, but nothing appears on screen. no logo, no beeps... im terrified Ive bricked it. I havent tried anything yet cuz I dont want to make it worse, what do I do now?
