Booting multiple OS at once.
 
Is there any option to boot multiple OS from the same system at the same time where each OS resides in different hard disk, displaying the status of each OS booting and after each one boots giving an option to switch over to another just like switching users in windows.

I only know of booting a single OS and then using apps like virtual box, qemu, vmware, and others running guest OS under a Linux host OS. Windows can run vmware and there are others as well.

AFAIK not. Most popular OS-es start the processor in Real mode. That is, single process, no memory management etc. For what you want, you need to activate multiple virtual machines in the processor.

The concept of virtual machines is used in products like VMWare etc. But those VM's can only be created if you have something to create it. As long as you don't have that 'something' you cannot create multiple machines.

The closest solution to your specification would be to create a Linux installation which is as light as possible, and then start up a number of virtual machines.

But it will be always 'on top of' one running system.

Its Dec. Edition under "Trible boot your laptop". Saw the laptop image and got the idea :)
