I have an asus zenbook ux31e. It stopped booting into windows 7 and I've been trying to figure out if it's a problem with the SSD or the motherboard. It will either boot into the bios when started up or come up with the message "windows boot config data file does not contain a valid OS entry).
I used a usb windows 7 boot and it booted into the windows options. Unfortunately the repair option doesn't fix the problem and even trying to re install windows doesn't work because it can't recognize the HD/SSD. In the bios it doesn't recognize any HD/SSD. I figure either the SSD has failed or the motherboard. I can't think of any other ways to diagnose the problem so any help would be much appreciated! I know I'm probably going to have to replace something, I just don't want to shell out on a new SSD if it's the motherboard that's failed.
Thanks in advance!
