lol i just came to edit the question out after reading the instructions
OCN makes me too lazy to read wats on the screen,
cant i install the Virtual hard drisk on a diffrent dirve than C
cant see the option for that
how big should i make the V HDD?
So create a virtual HDD, and you should choose "dynamically expanding" instead of fixed size. That means the VM will allow that .vdi file to get as big as you specify there, but it will stay actual size. So if you have 5.3GB of stuff stored on your .vdi, it will only use 5.3GB of your actual HDD. As you add more stuff, the .vdi will grow until it reaches the max capacity you specified. As you delete stuff, that .vdi will also shrink. If you tell it to make a 20GB fixed .vdi file, then it's going to take up 20GB right away no matter what, even if it's empty.
