Using a distinct partition for Windows 10 Preview won't interfere with your existing operating system.
Using a distinct partition for Windows 10 Preview won't interfere with your existing operating system.
It depends on how you set it up. If you keep your Windows 8.1 in a separate partition, you should be safe. The concern about Windows 10 Preview deleting files usually applies only to the preview itself, not to your existing OS. Just make sure the partition is properly isolated and backed up before proceeding.
Suggest using another storage device instead of changing the partition that runs your current operating system. A friend has access to both Windows 8.1 and Windows 10 previews on separate drives.
Are you sure about this setup? It might be better to try another partition just in case. Plus, the 2TB external drive is already packed with files.
You can test it in a virtual environment such as Virtual Box when you're concerned it might affect your existing setup.
However, the performance will be affected since it uses the same RAM and I only have four gigabytes available, which will cause significant issues.
