Windows 10 keeps rolling back

[WillRaven13]

Im running windows 10 build 10049 and I tired installing virtual box and it keeps rolling back before its done installing and then ends prematurely the end I tried the test build for windows today as well and same thing happened except it got so much closer to end.what should I do?

I also had the same issue with build 9926 (I think(the first build they came out with)) but I didn't try the test builds on there

I have the same issue. I tried all older versions, none worked, some of them was installed but cannot start from vagrant. I tried 5.0 beta, and the instalation is not finished and rollback. I had to use the windows 8.1 installed before and dual boot in it. I'm very disappointed !

Windows 10 does not yet officially exist, so it should come as no surprise that it is not yet a supported host OS either.

And incidentally: use with Vagrant is also not supported here.
