I need to install Windows 7, Windows Vista, Windows XP and CentOS on a single computer.
I am aware of virtualization but it would be better for my situation to install each OS and just switch between them without virtualization most because of video card, memory, etc.
I know how to install Windows and Linux with Linux being the boot manager but I don't know how could I install 4 OS and have the Linux OS to manage all the boot.
If some one could explain how would I have to proceed in order to accomplish this I would appreciate very much.
For example, is it all I need to install all the Windows and the Linux as last and set it as the boot manager or am I able to install the Linux first and the other after and still maintain the Linux as the boot manager ?
Or how this process would be done ?
