I have Windows 10 64 bit and virtualbox 5.0
When i try to press "Choose disk image..." inside a virtual machine, the machine just crash. But if i do the manual way by the settings then Storage and start the machine it works
. But now i tweaking just some games that could work. But it requeriers that i change cd in the installation. And we all know that i cant just turn down the machine and change cd, cuz that wont work 
.So how do i fix this ?
