  1. Custom-sized Windows boot drive when Clean Installing


    When performing a clean custom install of Windows 10 and the user wishes to generate a custom-sized Windows boot drive, there is a major fault in the process; I was clean installing Windows 10 v2004 Build 19041.264 x64.

    When users want to allocate a bespoke sized boot drive using the 'New' option, they have to change the size one digit at a time. In my case I wished to have a bespoke size of 500GB and had to change the size from 950000-odd to 512000 by keeping my mouse pointer on the 'down-arrow' for about 60-80 minutes until I lowered it to the size I wanted.

    You need to be able to just overwrite this field with the required size.


    It was not an issue until Build19041.264; previously all the system partitions were installed BEFORE the Windows boot partition; now, the 'Recovery' partition is created last of all, and once you select a size for the boot partition, it cannot be changed other than by doing a fresh clean install.

    :)

  2. 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.

    Windows Vista Clean Installation

    To do a clean install on a fresh hard drive with Vista on an upgrade disc, you have to follow certain steps. Buying a full install CD would've been easier, but using the upgrade disc only adds more time, so it's not that big of a deal.

    Follow the instructions here to do a clean install with an upgrade disc: http://www.vistarewired.com/2007/02/28/perform-a-clean-install-with-a-vista-upgrade-disc
