    Win 8 installation on new PC with XP


    Hey there,

    I've tried to find a solution to my problem, but haven't found anything that helps me with my specific situation.

    I plan on building a new PC using 1 SSD, and 1 HDD. I have a Windows XP installation disc, and I'd like to use that so I can save some money and upgrade it to Windows 8.

    I've seen how to clean install Windows 8 upgrade. I'm wondering how I should go about it. Do I install XP on the HDD, then upgrade and install Win 8 on the SSD -- is that possible? Or can I install Win XP on the SSD, then upgrade to 8 on there?

    I'm confused, and would like to see if you guys have a solution.

    Update: It looks like even though the XP installation will be 32-bit, I can clean install to 64-bit. If that's incorrect, please let me know.

    Thanks.

    Welcome to EightForums.

    No need to reinstall old Windows install.

    Clean the HD Drive, using Step one in this tutorial:

    & than Reboot PC to install.


    Clean Install with Windows 8 Upgrade

    Will your new PC have a uEFI BIOS?

    I believe it will have a uEFI BIOS, I bought a Asus P8Z77-V motherboard.

    But if I clean the HDD I won't be able to upgrade because Windows won't recognize a previous installation right?

    I'm trying to put together steps.

    1. Install XP - On HDD or SSD?
    2. Run Upgrade Assistant
    3. Boot from USB with Win 8 Upgrade
    4. Erase previous XP installation
    5. Install Win 8

    The new PC will have clean drives though, why would I need to clean them? I'm only using the XP install so the Win 8 upgrade will recognize a previous Windows installation.

    Also Win XP will not install on a uEFI BIOS.

    So, I can "upgrade" to Windows 8 without having a previous install? I didn't know that was possible.

    Still confused. The new PC will have no OS on it from the start. I thought I could install Windows XP onto it, then upgrade to 8. When you say "reinstall old windows install," I don't understand. I'm not reinstalling anything.
