It's not a good idea to install a beta OS over a main OS you are using. You may wanna grap any cheap hard drives you can find and install the Win 9 preview separately.

Why not simply go with a dual boot? Just put Win 9 Preview on another partition and you should be safe.

I'm certainly going to dual boot 9 and 8.1.1 with separate hard disks

Hi

"If the Windows 9 preview doesn't come with a System Restore capability to go back to 8.1, I won't be able to risk installing it. I can't be without a working computer. "

Make a system image of your hard drive using a program like Paragon Backup and Restore or EaseUS, TODO backup.
That's how I recovered Windows 8 when Windows 8.1 didn't work on my computer.

It's only a half hour to an hour to be back up and running just like it was to start with.

I plan on dual booting the Windows 9 install with Windows 8 to try it without risking my normal setup.
