I have a dual boot laptop with Linx Mint and Windows 10. When the computer is turned on, the boot manager presents 4 line items. The first is Linux Mint and the third is Windows 10 and, if I'm away and the computer is untouched,it boots into Linux. When booting up I'd like the boot manager to present two ICONS representing Linux and Windows and then wait for me to click on the operating system I'd like to boot. How can I do that?
