    VISTA+Win8 dual boot


    I cant remember exactly, i tried it a few weeks ago, it refused to install but ill find out exactly tomoro as its a bit late in my side of the world
    But still even if it worked my computer is deffinetly too slow, it couldnt be too different from vm ware
    The start menu lags and when i try a game like cut the rope it gives me a message saying my device is too slow. Even my old slow 600mhz android phone could do that without any prob

    You have to give it enough RAM. Since you have only 3GB, I would split it 50/50 between the host and the guest. And 25 to 30GB dynamic disk space. I have used vBox on a 1.8GHz duo core CPU and it worked conveniently.

    Games though are probably out of the question. Don't forget that your phone works with a RISC CPU. That is a completely different story. Cannot compare apples and oranges.

    It is possible to boot from a VHD under Vista but you'll need access to a Windows 7 DVD, as you'll have to replace some of the Vista boot files to support VHD booting.

    i gave it 25GB and 50/50 and then almost all my ram and it is still too slow in vm ware
    anyway vm box say this when i start it up, VT-x/AMD-V hardware acceleration is not available on your system. Certain guests require this and will fail to boot without it

    i have already said my computer is to slow for vm, at least with vista as host, so vm is NOT good for me
    please dont try to help me fix this vbox problem because I know it couldnt be much better that vm ware and anyway even if it was fast enough i dont like it, i can fullscreen with some black margins, which the mouse can go out on, so therefore its almost impossible to use app multi task or acess the other menu on right side

    so I dont want to use a virtual machine, tried and didnt like
    but still tanks for trying to help!!

    So vista does not support vhd dual boot, my computer is too slow for a vm

    is the only other option to partition my C drive and install there, vista home premium supports dual boot like this doesnt it?
    if so, can the partition be dynamic

    As I said in my earlier post, it is possible to boot from a VHD under Vista. See:

    Boot From VHD Replacing Vista or Windows 2008 Bootloader ...

    Although this is booting to a Windows 7 VHD, it should also work for Windows 8. Or you can partition and Dual boot conventionally.

    i dont know about messing with bootloaders, dangerous i think. would replacing it make vista start up faster?

    It won't have any impact on Vista boot time, it simply enables the an ability, which Vista doesn't natively support. That aside, if you're not confident making these kinds of change, I'd suggest using more conventional means, such as dual booting. There are plenty of free, third-party partitioning utilities, that will let you rearrange, divide and create partitions without loss of data - always backup anyway - or you can also use the built-in tools.
