If your virtual machine has snapshots, delete them before you resize a virtual disk and adjust disk partition size. It is recommended that you back up your VM before doing operations with disks. Changing disk partition size may be risky if you make a mistake during the configuration process. In this section, I explain how to extend partitions in Linux after expanding virtual disks.
There are different methods to adjust disk partition size and extend Linux partitions. You can use the command line tools or tools with the graphical user interface. I have a thin provisioned virtual disk Ubuntu The file size is displayed in bytes in the command line. Run the command to expand a virtual disk from 20 GB to 30 GB. Enter the virtual disk target size that you want to have — not the size of the increment you want to add to the virtual disk. In my example, I increase the size of my GB virtual disk to 30 GB by using the command like below:.
Select a vmdk disk file, not -flat. Enter the needed disk size and virtual disk file according to your needs and configuration. G means gigabytes, M — megabytes, K — kilobytes, T — terabytes, etc. If you want to have an eager-zeroed thick disk, use a command like this one vmkfstools -X 30G -d eagerzeroedthick vm-disk-name. Check the new size of the virtual disk:. New versions of Ubuntu have a built-in Disks utility with a user-friendly graphical user interface GUI that supports changing disk partition size with a few clicks.
Power on the virtual machine after extending your virtual disk, and boot Ubuntu Linux that is installed on the virtual machine. Choose the appropriate item once the Disks utility icon is found and displayed.
After resizing a virtual disk, Linux partitions are not extended automatically, and you see the unused unpartitioned space on the disk. If you have multiple partitions, you can change the size of those partitions in the Disks utility.
In the Resize Volume window, enter new parameters, such as partition size, free space following, or difference. As an alternative, move the slider from the current size to the desired size. Then click the Resize button. Parted is a command-line utility to manage disk partitions in Linux. Parted is pre-installed in Ubuntu. However, if this utility is not installed on your Linux, install this utility manually from software repositories with root permissions.
Unmount partitions before doing operations with partitions in parted. Operations with unmounted partitions can harm the data on the disk. Use the umount command to unmount a partition, for example:. I boot from the Ubuntu 19 live installation media in this example and select the Try Ubuntu option. Start a virtual machine. Do it promptly because you only have about one second to press F2.
After finishing the installation of a guest OS, the virtual hard disk drive on which the guest OS is installed is automatically set as the first boot device of the VM. Save changes and exit go to the Exit tab. Once you run a command in parted , changes are written to the disk immediately. Confirmation questions appear when you run commands to make changes with disk partitions.
My unused disk space is between Enter the number of the needed partition whose size you want to increase. Enter the end size for the partition in my case, the partition starts at kB and must end at GParted is an alternative edition of parted with the GUI. This utility is free, just like parted. Download the ISO bootable image from the official website.
If you boot from a Live CD with GParted , you can resize partitions on different Linux distributions, including Linux distributions without a disk partitioning utility that resizes partitions on the fly. You can also resize partitions on which Linux is installed when it is not possible to resize these partitions from the OS because the OS mounts and uses them for regular operation.
Select your language. I select 33 US English. Press Enter to keep the default value and continue, or type the needed option number, then press Enter. The interface of GParted is user-friendly. Partitions of the selected disk are displayed with information about them. In the opened window, enter a new disk size in megabytes or use the mouse to adjust disk partition size. In GParted changes are not written to the disk immediately.
You must apply configuration changes to write them. Now the partition size is increased to the maximum possible size on the expanded virtual disk of the VMware VM. Likewise, Linux users who utilized a Windows 10 license bundled with their laptop or desktop by installing Windows 10 in a virtual machine are also likely to be troubled by this update, unless they allocated a large amount of disk space on initial setup.
Without an ample amount of free space available when the update is started, updating to Windows 10 May will fail, often displaying error code 0x Windows Update does not verify that sufficient disk space exists before starting the update.
Rather than destroying the existing VM to expand the disk to allow for the installation, users can--with some manual effort--expand the existing disk image used with Windows 10 in a VM. Additional directions are also available for users of VirtualBox. Read the entire guide before performing any of these steps on your system.
Disks in Boxes expand dynamically, allowing the VM to report a larger size than is allocated on the host machine drive, but using only the real space taken up by the VM. In the terminal, navigate to the location of your virtual disk. Run the following command to increase the image size by 32 GB, replacing vmdisk.
The extension may be. The Windows 10 Disk Management interface. The "System Reserved" partition, first, is used for loading Windows. The C: partition is the live Windows 10 environment, while the last partition selected is a recovery partition. After installing the Oracle software on your host computer, click the shortcut to run the program and follow the steps below in order to create a new VM.
When you type the name of the operating system you will install on your virtual PC in the Name field, the Type and Version values will be automatically set by VirtualBox. For example, when you type Windows 7 in the operating system name if the version is set to 64 Bit automatically and you are going to install 32 Bit, configure the system architecture manually.
Since you are installing Windows 7 from scratch , you need to select Create a virtual hard disk now option in the Hard disk configuration window.
If you have a system that you have previously set up with Oracle virtualization software, you need to add the virtual HDD of that system with the Use an existing virtual hard disk file option. VHD is used for virtualization software from Microsoft. In this window, you must select how the virtual disk file will be stored on your physical HDD. If you do not want to fill the capacity of your host disk unnecessarily, you should select the Dynamically Allocated option. You can adjust these settings in the File Location and Size window to rearrange the location and size of the virtual disk.
Since it will be sufficient to use the 32 GB disk capacity that VirtualBox automatically determines, click the Create button directly. Open the settings to add the Windows 7 ISO file to the virtual computer you created or to enable the virtualization feature. In order to install either Windows or Linux operating systems on a physical computer, the boot order must be changed in the BIOS settings.
Next, the installation media for the operating system must be inserted into the optical drive and the computer must be started with the installation media. When installing a system on virtual machines, the boot order must be changed. Since Floppy is old hardware, disable it and configure the first boot order as Optical. Enable the 3D Acceleration option and configure the Video Memory value as MB in order to increase the image quality in virtual computers and to run applications or games containing 3D graphics properly.
After preparing your virtual computer and selecting the boot media, you will be ready to install Windows 7 with VirtualBox. After running your VM, you must follow the same steps as if you were installing a system on a physical computer. When the Windows 7 setup screen opens, select the display language, time settings, and keyboard layout you want to use your system with and click the Next button.
To create a new Partition on the virtual disk, select the disk and then click New and click Apply to confirm the automatically allocated disk space. Also, when you receive an information message that additional fields will be created for Windows to work correctly, click OK and continue. After the installation files have been copied to the disk, wait to restart your virtual computer within the specified time or directly click the Restart Now button.
If you want to set the password on your virtual system, fill in the relevant fields in the image below and continue. If you do not want to create the password, just click Next. If you want to use a licensed operating system on your guest machine, type your product key and click Next. You can check the Windows 7 system properties by first clicking the right button on my computer and then clicking Properties.
After installing Windows 7 on the virtual computer, you need to install Guest Additions in order to configure the screen resolution as full screen or use it in scaled mode and copy files from the host. Before installing Guest Additions on Windows 7, open the Device Manager on your virtual machine and check the drivers that are not installed or drivers that are not installed correctly.
If the image file of guest additions is not detected automatically on the guest machine, open My Computer and after viewing the content of the image file, run the VBoxWindowsAdditions-amd64 file as an administrator and click the Yes button in the User Account Control window.
In the Choose Components window, check that the Direct3D feature is enabled and click the Install button. After installing the guest additions on the guest machine, restart your system so that the changes can be applied to your system.
When your guest machine is turned on, open the Device Manager again and check that the drivers for the graphics adapter and other devices are installed correctly. Create a new text document on your host computer and drag and drop it to the desktop location of your virtual PC. When you examine the image below, you can see that the file transfer is done without any problems. You can see that the network settings are automatically configured when you want to access the Internet through the virtual machine.
Open the CMD command prompt on your guest machine and execute ping 8.
