I am trying to install a program from a dvd on an old laptop but am having a problem with changing the bios system from OS Boot Manager to USB CD/DVD Rom Drive.
I have moved USB CD/DVD Rom Drive to the list of option by using F6 but note that the arrow still remains againstOS Boot Manager, and after pressing F10 to exit and save, the required changes do not take place.
Can anyone help me an 86 year old computer novice, resolve this issue.
