I bought Sony VAIO SVS1511V9RB today and can't boot it from neither USB flash drive nor bootable CD. I've changed priority of boot drives to Internal CD-ROM, External devices, Internal Hard Disk, Network, and enabled external device boot. But after this only Windows was loaded. Also I tried to press F8, F9, F11 and F12, but also without success, Windows loaded from hard drive instead. I checked that my desktop booted from CD. Notebook can read CD in Windows, and it tries to read it while booting but don't print any messages and just load Windows. BIOS is Insyde H2O, version R0140C5.
Any ideas how to boot it from CD or USB Flash drive?
