How to Increase VirtualBox Disk Size(Windows 11 Host ) Ubuntu VM (Step-by-Step)
Description:
In this video, I will show you how to increase the disk size of an Ubuntu Virtual Machine in VirtualBox. If your Ubuntu VM is running out of space, this tutorial will guide you through expanding the virtual disk (VDI) and then extending the partition inside Ubuntu to actually use the new space.
Steps covered:
Shut down the VM.
Use VBoxManage to resize the disk or use VirtualBox GUI.
Boot Ubuntu and install GParted.
Extend the partitions to utilize the new space.
Commands used:
VBoxManage modifyhd "path/to/your/disk.vdi" --resize size-here

Key Steps :
===========
Increase VDI Size: Open Command Prompt/Terminal, navigate to VirtualBox folder, and use:
VBoxManage modifyhd "C:\Users\YourUser\VirtualBox VMs\Ubuntu\Ubuntu.vdi" --resize 50000 (resizes to 50GB) [1, 2].
Open GParted in Ubuntu: Boot the VM, open terminal, and run sudo apt install gparted then sudo gparted [2].
Resize Partition: In GParted, find the partition (usually /dev/sda1 or ubuntu--vg), right-click and choose "Resize/Move" to fill the unallocated space [2].
Apply Changes: Click "Apply" in GParted and restart.
Note: Ensure you have a backup of your VM before resizing.
