ok weird one i ran teh MSI Live Update 6.2.0.74 BIOS/firmware update on my work laptop because teh support page said it improves stability. partway through, the progress bar froze. 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. I'm terrified I've bricked it. I haven't tried anything yet because I don't wanna make it worse. what do I do now? what am i doing wrong??
