In Mac OSX, you can create a Boot Camp partition, install Windows on it, and then later by using Parallels you can boot into that OS virtually in OS X! Its awesome, I've been using it on my macbook.
So, what I want to do now is, on my desktop running Windows 7 and Ubuntu 9.04, I want to virtualize my Windows 7 OS in Ubuntu. I have a copy of VMware Workstation, but I can't figure out how to do it that way. The only thing I've figured out is to convert a physical installation into a virtual, and boot from that. However, that doesn't mean I'm booting from that physical drive, meaning no changes are retained. Once I convert the installation to a virtual machine, it becomes a separate entity.
What I want to do is be able to dual boot and also have Ubuntu boot my physical Windows installation virtually when I want to. Can this be done through VMware Workstation? If not, how can I do this?
