Tried to boot a usb3 stick with windows 10 preview, a no go. Tried a bootable cd, no go.

What's a poor chap to do if want to install a fresh copy of windows?

Tried disable secure boot in bios, tried create new boot device in bios, no go.

I'm stupid, but this is ridicules, desktop pc's with ufi bios boot usb/dvd just fine.

Is there a way to fix this booting problem? A new bios perhaps?

All's well. Got a respons from asus tech support:

Press F2 during startup to go to bios.

Set Secureboot to Disabled.

Fast or Quickboot to Disabled

CSM to Enabled.

USB boot/Legacy support to Enabled.

Save and exit. Press esc to get boot meny.

Now can boot usb and optical disks.
