We found out that the reason behind "Boot from USB" disapearing is the bios update.If you update your bios -that you have to,in order to install the network drivers - the boot from usb disappears.
We found out that the bios update removes the "Boot from USB" option.The thing is that you need to update the bios in order to install the network drivers.
Ok, i think i found the solution. My bios is the A08 and with 8.1 bootable usb i changed the uefi to legacy. Although when i changed it to legacy no device was shown at the list, the windows installation started normally! When the first reboot was auto done by installation, i instantly removed the drive so as the installation not to start again and after the windows logo showed i plugged in again my flash drive. After i put my settings and saw my desktop i rebooted and instantly went to bios settings and changed back to uefi and activated secure boot! Drivers installed perfectly because of the bios update and really happy now!
