Saw a old post about this type on Ubuntu And following that didnt help me! Any solution? Several of my old VMs seem to hang on bootup. If in Grub I select "recovery mode", the last messages displayed on the screen are:. Switching it back to "Legacy" immediately makes it hang on boot, so I know for certain this is the key to the issue in my case. Did you allocate enough RAM to the virtual machine? I discovered when I ran Ubuntu Looked like there is 'something' with the number of processors.
Based on the other answers, there does not seem to be a 'right' number that works for every system. I then realized that I also have an Ubuntu This one still works. I noticed that for this virtual machine the Paravirtualization Interface is set to Default, while for my Desktop VM the one I was having problems withit was set to Legacy.
I changed it to Default and now it works, with any number of CPU's. So the solution, for me, was to: Set Paravirtualization Interface to Default. For me, I had to disable hyper-v before I could get it to work. Increasing the other options listed in this answer didn't help. This can be done by searching for "Turn windows features on or off" in Windows, then un-checking Hyper-V you need to restart your computer after. Was freezing on "Booting smp configuration" after upgrading to I am using Virtual Box 5.
I was trying to install Ubuntu and it was painfully slow to boot and log showed guest would become unresponsive every few seconds. What finally worked for me was to change the paravirtualization to legacy in order to complete the install.
Then the guest would hang on start up. I had to change the paravirutalization mode back to default in order to successfully boot. I had a similar problem and this is what I did to fix it. My 3D acceleration is still on and I have video memory at MB.
Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. I recently transferred a virtualbox machine from my laptop to my recently reinstalled desktop. The image works fine on my laptop, but when I try to boot it on my new machine, I get dumped to an "EFI Shell" where it asks me about my hard drives rather than booting the machine. I want it to boot to the actual machine image rather than this shell.
How can I fix this? It turns out that as I was messing around with getting the machine to load due to Virtualization technologies being disabledI clicked one too many items on the image settings page.
To fix this, go to the "Settings" page for the virtual machine, and click "System". Then click "OK", and try to boot the machine again.

This topic has been locked by an administrator and is no longer open for commenting.While installing macOS specifically Mojave is pretty easy on an actual Mac, but if you are a Windows user, that is not the case.
One of the problems that most users encounter when installing to boot is the broken EFI Internal Shell which typically prevents booting machine into the installation process and getting Mojave installed.
The Shell usually appears as a bunch of commands without allowing you to skip, continue, or get into the installation except entering commands. There are some reasons and fixes for them. There are a couple of reasons why this happens. One of the most basic reasons is not closing the machine app entirely before applying the VirtualBox code.
When you create the virtual machine and go to apply the code to VirtualBox on Command Prompt, we have clearly noted you to first close the VirtualBox entirely. For anyone who is stuck at Shell, you can probably solve this by creating a new virtual machine from the instructions guide and basically apply the patch command when the virtual machine is completely CLOSED even from Task Manager.
This will definitely help if the problem was due to the reason so make sure you do it next time beforehand.
It can also be updated but when it reboots in the middle of update you should press the F12 key to get back into EFI Shell where you should select boot.

These packages are only required if you want to run the Oracle VM VirtualBox graphical user interfaces.
In order to run other operating systems in virtual machines alongside your main operating system, Oracle VM VirtualBox needs to integrate very tightly with your system. To do this it installs a driver module called vboxdrv into the system kernel. The kernel is the part of the operating system which controls your processor and physical hardware. Without this kernel module, you can still use the VirtualBox Manager to configure virtual machines, but they will not start.
Network drivers called vboxnetflt and vboxnetadp are also installed. They enable virtual machines to make more use of your computer's network capabilities and are needed for any virtual machine networking beyond the basic NAT mode. Since distributing driver modules separately from the kernel is not something which Linux supports well, the Oracle VM VirtualBox install process creates the modules on the system where they will be used.
This means that you may need to install some software packages from the distribution which are needed for the build process. Required packages may include the following:. Also ensure that all system updates have been installed and that your system is running the most up-to-date kernel for the distribution. The running kernel and the kernel header files must be updated to matching versions. The following list includes some details of the required files for some common distributions.How to set up a virtual machine using VirtualBox
Start by finding the version name of your kernel, using the command uname -r in a terminal. The list assumes that you have not changed too much from the original installation, in particular that you have not installed a different kernel type. With Debian and Ubuntu-based distributions, you must install the correct version of the linux-headersusually whichever of linux-headers-genericlinux-headers-amd64linux-headers-i or linux-headers-ipae best matches the kernel version name.
Also, the linux-kbuild package if it exists. Basic Ubuntu releases should have the correct packages installed by default. On Fedora, Red Hat, Oracle Linux and many other RPM-based systems, the kernel version sometimes has a code of letters or a word close to the end of the version name.
For example "uek" for the Oracle Unbreakable Enterprise Kernel or "default" or "desktop" for the standard kernels. In this case, the package name is kernel-uek-devel or equivalent. If there is no such code, it is usually kernel-devel. If you suspect that something has gone wrong with module installation, check that your system is set up as described above and try running the following command, as root:.
See your system documentation for details of the kernel module signing process. Oracle VM VirtualBox is available in a number of package formats native to various common Linux distributions.The following information on this error has been compiled by NeoSmart Technologies, based on the information gathered and reported by our global network of engineers, developers, and technicians or partner organizations. When an operating system is installed on the hard drive, the installer marks the partition that contains the boot files for that OS as active.
Every time a computer with that OS is turned on, as part of the boot process the BIOS loads and starts the first sector on the bootable drive. The first sector on that disk typically called an MBR or Master Boot Record contains code that checks the partition table for a partition that is marked as active, and loads the first sector of that partition the boot sector.
This is usually caused by errors made while configuring the partitions manually. If MBR tries to pass execution on to an active partition that does not have a valid, executable bootsector, then this error may also appear.
The bootsector can be sometimes damaged by disk write errors, boot sector infecting viruses, or power outages. If your PC did not come with a Windows installation disc or if you no longer have your Windows setup media, you can use Easy Recovery Essentials for Windows instead.
