BIOS boot list doesn't have CD/DVD and USB options anymore - Lenovo G50-70

[lukigno95]

Hi, I have a lenovo G50-70 with the newest bios (uefi??) version but i have a problem because in the boot tab in the bios setup I don't have anymore the cd/dvd and usb boot options.

I don't know why they disappeared but I'm sure that before these options were available, furthermore in the "advanced restart" menu of windows 10 I have these options but when I try them the system prompt me an error telling me "this option isn't available in the boot list".

I tryed disabling secure boot, and backflashing an old bios firmware but they didn't fix the problem. (Now I have reinstalled the latest bios firmware)

Anyone could help me please?

As well as disabling secure boot, you also have to enable legacy BIOS (ie not EUFI).
