First be clear
The specific problem is that the image of guest additions is successfully inserted under the win7 virtual machine, and after the successful installation, and restarting, the win7 virtual machine still cannot be fully screened. It can’t be solved even after repeated installation, and the screen resolution can’t be modified.
My solution
After inquiries, I tried a combination of several options. But the problem is that it is not clear whether it works together or whether one of the solutions is ultimately effective. But all in all, I did the following solutions:
- Adjust the video memory size in the display, it turned out to be 24MB, but I adjusted it to the maximum 128MB
- Completely close the virtualbox software
After these two programs are combined, reopen the virtualbox software, win7 can enter the full screen normally.
peace out:)
