Dual boot on already-installed system
Hi all,
I'm a newbie here so please bear with me, I am running Fedora 25 Cinnamon and Windows 7 each on separate hard drives in a Dell E6420 laptop.
At the moment I am using the F12 function to interrupt the boot sequence if I want to run Windows (Linux is on the first hard drive).
On my old desktop PC many years ago I did manage to get grub configured to have both OS's showing on bootup but I can't for the life of me remember how I did it.
Can anyone advise (in simple terms, please..!) I have seen guides on how to set this up when installing Linux, but not how to edit grub on an already-installed system.
Thanks in advance,
Ria in Aberdeen
