I got some days ago a ZENBOOK UX51VZ, I hated Windows 8 therefor I successfully installed Windows 7 with all the drivers, everything was working fine; then I stupidly decided to update the BIOS to the 204 (2012.12.25) update, after I flashed and restarted the ultrabook everything went wrong: there is no boot options at all! Now I'm literally stuck in the "Bios SetUp".

Note: The hard drives are intact, they are working find (I think so)

I used:

Windows     BIOS Flash Utility
BIOS FILE:  UX51VZAAS204.zip

Now I can't even recognize an external CD-drive!

Take a look at the BIOS:

I had the same issue with my machine and it took 5 minutes to fix.

When you flashed the BIOS, it reset the defaults, which includes enabling secure boot and disabling CSM (compatibility support mode). Since you aren't using Windows 8, this is bad.

Flip those two options around and you should be good to go.
