I am going to be setting a Quad Boot, And i want to use Windows 7 & Windows 8.1 and I will be using Two versions of Linux with Two Hard drives...
Which Is the best Method to do this ? Plus What boot loader/Manager to use ..
You'll be using GRUB since you'll be using Linux distros. It's not gonna be hard to do. Just load Windows 7, then Windows 8, then your two Linux distros.
Just FYI, Whatever Linux you install last will be the OS that will manage GRUB. So if you install Ubutnu then Linux Mint, Mint will be where you will need to update or make changes to grub.cfg.
