I want to restore to factory my Z3-715 All In One computer with DVD ROM 4 disks.
Customised BIOS for boot with DVD ROM.
Did not work.
Computer remain indefinitely booting with Windows traditional boot.
Even when click F12 and choose DVD ROM as boot option
How can I overcome this problem ?
P.S. : I am not a trouble shooter. There was a mistake !!! I am a medium operator .
