I have Lubuntu running on VirtualBox properly.
I followed the same procedure for installing CentOS 7 on VirtualBox. However, once I see the CentOS installation menu, I click on "Install CentOS", and then black screen shows up!
Again, once I click on "install CentOS 7", I see "black screen", that`s it.
Note that I am aware to the fact that CentOS 7 is 64 bit, so I enabled virtualization in BIOS in advance.
I tried Minimal ISO CentOS and DVD ISO CentOS, but both causes black screen to appear.
I even clicked on troubleshooting option in the installation menu, which gives an option to install CentOS 7 in 'basic graphic mode' but I still get black screen.
What ever I try, I can`t install CentOS 7 on Virtualbox (4.3.26 - Latest edition).
