    Hi, I've installed Virtualbox to run Win7-64bit.

    However, I've gone through the whole process only to see the error "no bootable medium found". I'm guessing this is something to do with my copy of Win7 which I created using Imgburn from a .img file on my PC. The Win7 DVD I created now has, and Win7-P-Retail-en-us-x64 files on there.

    So, if I clicked the Win7 file on a Windows machine it would allow me to install but VirtualBox doesn't appear to like it..

    Any ideas where I've gone wrong?


    PS - I have a 2011 MacBook Pro 15" 2.2..

    Have you burnt Windows 7 to a CD? It's much better to tell VirtualBox just to use the image file, rather than an actual disk.

    If you have the CD, and wish to use it, you need to set VirtualBox to use the host drive for the CD within the virtual machine settings.

    Is your install a "upgrade" by any chance?
    Some "upgrade" installations literally only seem to upgrade windows vista, while other will do a fresh install. I seem to remember this happening even with my fresh install upgrade in virtual box, if i remember correctly i just made a disc image of the disc, mounted it in VirtualBox and set it as the boot device

    VirtualBox has all sorts of challenges on K64 - have you checked which kernel you are booting?
