Accessing Ubuntu File System through GRUB Command Line in VirtualBox

In some cases, you might need to access the Ubuntu file system through the GRUB command line in VirtualBox. For instance, if you cannot seem to access the filesystem or need to delete files in recovery mode. This article will guide you through the key concepts and steps required to accomplish this task.

What is GRUB?

GRUB (GRand Unified Bootloader) is a popular boot loader used in Linux distributions, including Ubuntu. It allows users to select the operating system they want to boot and provides a command line interface for advanced users to perform various tasks such as accessing the filesystem, resetting the root password, or fixing boot issues.

Accessing the GRUB Command Line in VirtualBox

To access the GRUB command line in VirtualBox, you need to reboot your Ubuntu system and interrupt the boot process before the operating system starts loading. To do this, follow these steps:

Shut down your Ubuntu system in VirtualBox.
Start your Ubuntu system in VirtualBox and immediately press the Esc or Shift key to display the GRUB menu.
Select the 'Advanced options for Ubuntu' using the arrow keys and press Enter.
Select the '(recovery mode)' option and press Enter.
Wait for the system to boot to the recovery menu, then select the 'root' option and press Enter.

You should now be presented with the GRUB command line. Before proceeding, you need to remount the root file system with read-write permissions using the following command:


mount -o remount,rw /

Deleting Files from the Ubuntu Filesystem through GRUB Command Line

Now that you have access to the Ubuntu filesystem through the GRUB command line, you can delete files by using the rm command. For example, to delete a file named myfile.txt in the root directory, you would use the following command:


rm /myfile.txt

Be careful when deleting files through the command line, as there is no confirmation prompt, and deleted files cannot be recovered.

GRUB is a boot loader used in Ubuntu that provides a command line interface for advanced users.
To access the GRUB command line, interrupt the boot process by pressing the Esc or Shift key and selecting the '(recovery mode)' option.
Remount the root filesystem with read-write permissions using the mount -o remount,rw / command.
Delete files using the rm command with caution.
