Minecraft no driver support?

What should I do?

Update GPU driver.

However, I do this on a virtual PC (VirtualBox). Do I still have to install the drivers from my GPU in the PC?

You may also have to install the driver in the virtual machine, but I'm not familiar with anything like that.

OK.

In the VM you do not have a real graphics card, but only a virtual graphics card, which is only sufficient for the bare essentials…

You could transfer a real graphics card into the VM via PCI pass-through.

Why do you want to start Mc in the VM at all?

And yes you have to install in the VM driver if the pass-through is set up. But without a proper graphics card, no drivers will bring you anything.

If this is VirtualBox running, make sure you have installed the (current) guest additions.
