Is it possible to dual boot two OS's at the same time?
For example: I'm currently dual booting Ubuntu 11.04 and Windows 7. Ubuntu is running on a single 500gb HDD, Windows 7 is running on 1TB RAID 1 mirror. To switch between the two OS's, a reboot is required. Is it possible to switch between the two OS's without a reboot?
NOTE: I'm fully aware of the capabilities of VirtualBox and VMWare Player - I use both. Please don't answer "Use Virtualization!"
EDIT: If this is not possible can you share why it's not possible? To me, it doesn't seem like it would be that difficult. Keep in mind that my vision is unencumbered by knowledge!
