virtualbox ubuntu stuck on loading screen

Since RAM is a major concern to prevent freezing and just a poor overall experience, it’s best to ensure you allocate at least the minimum amount of RAM needed to run Ubuntu to your VirtualBox instance. How can I choose the right amount of RAM? If you’re encountering freezing, this is one of the first things to try turning off.

While it sounds like something you’d want, it rarely enables any actual gains in performance. No matter whether you’re running Windows, macOS, or even Linux, 3D acceleration can cause plenty of problems in VirtualBox.

Installing an earlier version of Ubuntu may help eliminate the freezing issue.

So, the problem could easily be with Ubuntu and not VirtualBox. For example, if you search for “Ubuntu 20.4 LTS freezing” on Google, you’ll see a lot of complaints. Not only will you possibly solve your freezing problem, but you’ll get new features as well.Īlternately, if you started using VirtualBox with a newer version of Ubuntu, check to see if there are any freezing issues with that version. If a certain version of Ubuntu never froze in the past, you can try installing an older version of VirtualBox.Ĭonversely, you might try running a newer version of Ubuntu. Some users have found that different versions of VirtualBox and Ubuntu sometimes just don’t get along. If this doesn't solve the problem, the downloaded iso image file might be damaged.No program is free of bugs, and this goes for both Ubuntu and VirtualBox. Otherwise, I suggest you try the following:Īt the same screen you've posted, hit the down arrow key to highlight Troubleshooting, then hit the Return key.Īt the next screen, hit return to choose the first option to boot in basic graphics mode. However, since you run VirtualBox, the problem shouldn't occur with a VM guest system, which is shielded from the physical hardware.ĭid you verify that you have Hardware Assisted Virtualization (VTx, amdv) enabeld in your PC BIOS? If I remember correctly, a grey or black screen may indicate a problem with the video driver and kernel Kernel Mode Setting (KMS), which is a method in newer kernels for setting display resolution and depth in the kernel rather than user space. Pressing any key should abandon or reset the countdown. You do not need the UEK boot images and source images - they do not contain the OS installation. You will need to start the system using the binary distribution, which is about 4.5 GB large.
