And there we have it. Redmond had already announced that Windows 8 users will be able to download and install the upcoming public preview version of Windows 8.1 from the Windows Store.
But the software titan will also release standalone ISOs that will be available on its official website.
The ISO images are specifically designed to help users set up dual-boot configurations while also keeping the current version of Windows 8 running as it is. It will also allow users to install the operating system on a different partition or a virtual machine.
Microsoft explains in these leaked Q&A documents:
“If you want to install as a dual boot, we do NOT recommend downloading the preview from Windows Store. Installing from the Store will upgrade the existing Windows 8 OS on that partition to Windows 8.1 Preview.
You will not be given an opportunity to select another partition, so you would need to already have a dual boot system installed in order to install Windows 8.1 Preview as a dual boot through Windows Store.”
So essentially, PCs must already be set up as dual-boot systems before downloading the Windows 8.1 preview ISO files as hey will not allow users to select another partition on their PC.
The Q&A also states that people who have Windows 8 Pro with Media Center on their PC will find the Media Center features removed if they download and install the Windows 8.1 Preview ISO. These can be put back by either reinstalling the Windows 8 Pro pack or Windows 8 Media Center product key.
