    How to change system partition letter in a fresh install?


    Is there any way to change or tell windows which letter to use for the default system partition?

    By default it picks it as C, i want to pick something else while the windows is still in installer mode and didnt start to copy files to drive.

    Windows 8.1 64 bit pro, installation in UEFI mode with GPT file system.

    You can do this but it may cause problems if you use poorly designed software which assumes the OS is installed on the C: drive.
