I have a system in which I have installed Windows 7 first. I then installed Ubuntu 12.04 (Precise Pangolin) to the system. Now, the boot manager is GRUB and everything works fine as Ubuntu detected that Windows 7 has been installed already.
Now, I would like to install Windows 8 too. I plan to install using a bootable USB stick (it doesn't matter which medium I prefer though, does it?). I have done some research and all the materials I can get state that I cannot practically install Windows 8 after Ubuntu and get all the three OSes to run. Is that really true? If not, how can I do it?
I want all the three operating systems to work perfectly.
