    Dual boot from existing Win8 on same disk


    Hi,

    I just received an Asus Zenbook with 8 preinstalled.

    It was configured with static IP and my office configuration, I would like to split the existing partition, create a new primary partition and clone the Win 8 installation in the new one.

    Then set up a dual boot configuration, so I can have a clean "office config" and an "home config" with the same licenses and software in which I can mess with the configuration and setup my home stuff (DLNA server, access to home headless server, software to flash android handset, ecc).

    I did that with WinXp a couple of years ago and everything was working ok using Easus, but I am out of the scene since then and I wouldn't like to miss some steps.

    I tried to google it but I found a lot of not relevant results...

    Is there anyone that can help me with that?

    Thanks

    Sergio

    Hello,

    I have bought windows Pro to do as suggested but I still can't install a side copy of Windows 8 along my existing Win8 partition.

    I receive the message "partition is of the gpt style" and I can't proceed.

    This is my config.

    From reading around it seems I have to delete all the partitions and start from scratch but I don't want to do that because the existing first primary partitions contains software for my job and I can't re-install it.

    How can I proceed?

    Thanks!

    Did you create partition D? Is that where you are trying to install you new copy of Win8?

    I found D already existing. I tried to delete it and install Win8 on it but no joy.

    Currently it hosts a VirtualBox with the Win8 i purchased but this is not meeting my goals, because it is not performant and I ma facing several limitations on USB peripherals it can handle (my garmin forerunner 305 for instance...)

    I can delete D and use it with no issue.

    Thanks!

    You are not booting the Windows 8x64 DVD in UEFI mode or Booting x32.

    I booted from Win8Disk and select the D partition to install in advanced mode

    Ok, the solution was to copy the dvd content to an USB key and UEFI boot from this.

    I don't know why but my zenbook didn't allow to UEFI boot from my external USB dvd reader.

    I still received a warning about the fact that partition order was not ideal but I continued and I am now writing this from my second Win8 installation.

    Thanks to all!
