I am trying to boot into my usb drive to install linux, though, I am unable to do so because the secure boot violation keeps popping up. So I searched it up and I found out that I had to disable the secure boot in the advanced options and then change the OS type to Other OS. However, I cannot find OS type setting anywhere. For reference, I have an Adolbook 14EA that I have just purchased less than a week ago. Can someone please tell me how to change that settings? and if not let me know if there is any other solution for this secure boot violation error.
