  1. Unable to perform a Windows 10 Clean Install


    Because my PC has many issues I want to do a clean install. However, I am having the following issue. When I go to start the install to my PC C drive, I get this error message. "Windows cannot be installed to this disk. The selected disk has an MBR partition table, Windows can only be installed to GPT disks onEFI systems." BIOS Mode Legacy. Is there a Registry change that I can do to convince the Windows 10 installation that my PC has a Legacy BIOS and is not UEFI or EFI?

    Thank You

    :)

  3. Clean Install Workaround for Vista

    You may remember this news story on techPowerUp! a couple of days ago relating to the lack of clean installs when using the Upgrade Editions of Vista, which required an old OS to be installed. However, Paul Thurrott has managed to find a workaround for this issue, which ironically lets users do a clean install Vista without any previous version of Windows, albeit a little tedious. Here are the steps:
    • Boot from the Windows Vista Upgrade DVD as normal
    • When prompted for a product code, leave this blank
    • Select the version of Vista you have purchased and let Vista install
    • When you boot to your desktop for the first time, run the Vista setup from Windows
    • This time enter your product key
    • When asked whether you want to do an Upgrade of Custom install, select custom and choose a clean install
    • Windows will now install for a second time and you should be able to activate it
    Remember, these steps are only advised for use in order to achieve a clean install of Vista, it is only legal to use the upgrade editions if you have previously purchased the appropriate version of Windows.

  4. Unable to perform a Windows 10 Clean Install

    Clean Windows 10 (?PRO?) install

    I have bought a legit "Windows 10 Pro" key of a key website. It is legit since i'm currently using it for over a year now. I currently have Windows 10 Pro installed on my PC and I want to do a clean install. I just can't find the windows 10 Pro download in the tool. But if i could use a windows 10 pro key with a normal windows 10 install, I'll be good to go.
