I have a Win 7 Host up and running with a Win XP guest. A few things to iron out, but it works well.
I have been trying to install an Android 4.2 or 4.3 guest, but have been running into the same problem with both.
I understand that it needs to be installed as a Linux guest according to https://forums.virtualbox.org/viewtopic ... &t=57296&p and the instructions I have found elsewhere. As installation references I have followed the steps at:
http://www.pcworld.com/article/2048220/ ... ur-pc.html
and one or 2 other pages that are basically the same instructions.
I run into the same problem every time I try it. I will get to this screen, go to the installation, and run it.

It goes through some steps with text on the screen, which runs too fast for me to pause for a screen shot, and returns to the above screen.
This happens every time I try to install, or run without installation.
I know there is a file you would like to see for troubleshooting, so if someone would tell me the file I need, and where to find it, I'll post it.
Any help will be much appreciated.
