I want to use Android-x86
to test and debug my App.I tried other versions of Android-x86 before successfully,but there is an erroe in about android-x86-4.2.So I ask
I have HP430 Laptop with win 7. I had the same problem. But I figured out the solution.
While booting the computer with win7 I entered BIOS menu. There was a option to optimize pc for virtualization.I selected it. After that every thing ran smooth.
Later I noticed in virtual box that, in system settings the acceleration type was VT-x AMD, Nested Paging,PAE/NX. This was different before optimization.
Hope this gives some idea.
