Windows 10 Upgrade Reservation and Information

Does anyone know if we'll be able to install Win10 to another drive? I have Win7, Win8(8.1) each on there own partition and I don't want to lose then, so I'd like to put Win10 on another drive...
Also can it be saved somehow as an iso or will we have to wait?

 

Hi Alpha_and_Omega, Like Evan said - it will install on an empty HDD. I have 2 comps (Gigabyte M/B in one and Asus in this one). I have installed W10 Insider Preview Evaluation Build10130 on both with clean HDD's.
I have been through most of the Build updates provided by MS and it's been flawless so far.
I've installed some of my usual Software on the drives and all work OK. I've even got the Trial MS Word 2016 installed and it works great. Neil.

 

The problem with rolling back from a Windows 10 install is that 10 never installed properly--and my whatever was running on my display said that it wasn't able to properly roll back to windows 7 (what was on the laptop before). Fortunately, this was after a decision to reinstall Windows 7 anyways (so it was going to be done, regardless). But I'm not sure I want to risk another reinstall of Win7 and my progs, unless Windows 10 has been refined a bit. I'll do it via the update cycle that everyone is talking about, so (theoretically) if it borks, I can simply roll back the update.

But I'll wait a few months, for as many glitches to be taken out, before I take the plunge. Take the plunge I will, but I'll wait a while--perhaps during a vacation.
