I have Win7 and Ubuntu installed on my PC, and I can choose which to run at boot time. I would like to be able to run the Ubuntu from within the Win7. Tools like VMWare allows one to create a new installation of a guest OS, which could then be run alongside the hosting OS. However, I already have the Ubuntu fully installed on my hard drive, and I'd like to maintain the dual boot option.
Ideally, I'd like to be able to create a new virtual machine on my Win7, but instead of installing a new guest OS, just direct it to the existing installation. Is that possible?
