    I'd use 2 machines - one for windows 7, and one for Windows 8 - and run the Windows 8 as a virtual desktop in remote desktop or VNC.
    What we need is something akin to XPMode - with tight integration with terminal services, so that both OSs can integrate with the same software, documents and file system.

    Failing that, a nice Metro app that can run your second OS of choice in its own workspace.

    Now, most Virtual PC software lets you do that on XP, but in Windows 7 and 8, this is difficult because of the extended security regarding accessing hard disk partitions directly from software.
    When have you ever been able to run two physically installed desktop operating systems simultaneously on the same machine?
    (Note: I've never used Virtual PC software on XP).

    If you have W7 Ultimate you can dual boot using a W8 VHD (that's how I run it).

    I multi-boot my PC:

    • Ubuntu 10.04 (install)
    • XP SP3 (install)
    • W7 Ultimate (install)
    • W8DP (VHD)
    • W8CP (VHD)
    • W8RP (VHD)

    GRUB offers me:
    • Ubuntu 10.04
    • W7 Ultimate

    If I choose W7, I get this boot menu:
    • XP SP3
    • W7 Ultimate
    • W8DP (VHD)
    • W8CP (VHD)
    • W8RP (VHD)

    The VHDs are all on the same HDD partition.
    This could work, however it would require a lot of tweaks to my system, including copying an entire operating system to a file! Its possible, but if Windows would allow me to do what I've been trying to do, it would make my life a whole lot easier!

    But it works in VMWare Player without problems:
    Adding a phisical drive to a VM in Win7 x64 and it works.

    UAC prompts when you're adding the drive but it gets over with.

    Like I said, you could do this in XP, and VMware still provides the option, it just doesn't work in 7 (or 8). I believe VirtualBox has the same problem.

    I'm aware you can boot from a VHD, but doing so is significantly slower than a physical partition. The file translation layer adds significant overhead. It might be an option though, if you have enough disk space to convert the physical partition to a VHD. (Sysinternals has a tool called Disk2vhd to do this).

    Hopachi: I'm surprised if that's true. VMware workstation doesn't work, and there are lots of complaints about this on their support boards.

    There seem to be some problems you're right:VMware Communities: How To: PhysicalDisks on Vista and Server 2008 (Windows7)
    But that doesn't explain why I was able to use a physical drive.

    I'm using VMware Player 4.0.3 on Windows 7 x64.

    Of course you cannot use the drive your booted with. But using another available physical drive worked.

    I don't have the VM anymore but maybe I'll try that again to see what I can get. It should work again.

    Because of nt6.x and nt7.x new security mechanisms, it is not possible to write directly to fs sectors on mounted volumes. In turn, it is not possible to use physical disks in virtual machines under vmware on Vista, Server 2008 and Windows7
    It was a NTFS drive indeed, AND I wasn't writing, just reading.
    Interesting.... So I suppose writing wasn't possible for me neither, but I didn't got any warnings nor errors.

    On my PC, the W8 VHDs boot faster than W7 (installed) does (6 -10 seconds faster).

    I did it with only one problem. I couldn't get Win 8 to go full-screen within the Win 7 Virtual Machine. So I now use a dual partition.

    There is also the VBox User Manual: 9.8 Advanced storage configuration

    This should work on Windows as it works on Linux.

    I've noticed that too.
    But as fafhrd said, in another thread i think, Win 8 uses swapfile.sys and that quick boot, hybrid stuff and that makes the difference.
    Without this trick, Win8 would boot with the same speed as Win7 I guess.
