I just finished installing Windows 10 preview, build 10130. But I wanted it to use its own system partition. Instead, it detected my other Windows installations and reconfigured the system partition that I use for those installations. I have Windows 7, and Windows 8.1 on one HDD. I wanted to install Windows 10 on a second HDD.
Is there a way to set the system partition during installation setup, to explicitly tell the installation program what physical drive and what partition I want to use as the system partition? I had created a first primary partition of 512 MB and set it as active in Diskpart. Why did it not take that primary, active partition and use it as a system partition? I also created one big extended partition and one logical partition to hold Windows 10.
This is what I wanted:
HDD0:Windows 7 (primary, active, system)Windows 8.1 (logical)HDD1:boot_win10 (primary, active, system)Windows 10 (logical)This is what I have:
HDD0:Windows 7 (primary, active, system)Windows 8.1 (logical)HDD1:Windows 10 (logical)I want the HDD that holds Windows 10 to be independent of the other Windows installations. For that to work it needs its own system partition and its own bootloader and boot manager configuration. What can I do at this point without having to reinstall Windows 10? If I do reinstall, how can I make sure that the setup will use the same HDD for system partition? Is it possible?
