Hi,
Earlier I installed Oracle VM VirtualBox Manager on Window 7 Professional and while creating new virtual box, I was able to select Oracle Linux 64-Bit. Now I installed Oracle VM VirtualBox Manager on Window 8 and while creating new virtual box, it's showing only 32-bit operating systems.
Few information,
Window edition - Window 8.1
Processor - Intel Core i5
System type - 64-bit operating system, x64-based processor
VirtualBox Manager - 4.3.20 r96997
Please let me know if I can provide any other information. If this post is duplicate, please direct me to existing post.
Thanks,
Prashant
