Create a virtual machine with Hyper-V Manager

1. Open Hyper-V Manager by either pressing the Window’s key and typing “Hyper-V Manager” or by finding Hyper-V Manager in your applications.
2. In Hyper-V Manager, select Action > New > Virtual Machine to bring up the New Virtual Machine Wizard.
3. Review the ‘Before You Begin’ content and select Next.
4. Give the virtual machine a name. Note: This is the name Hyper-V uses for the virtual machine, not the computer name given to the guest operating system that will be deployed inside the virtual machine.
5. Choose a location where the virtual machine files will be stored such as c:\virtualmachine. You can also accept the default location. Select Next when done.
6. Select a generation for the machine and select Next. Generation 2 virtual machines were introduced with Windows Server 2012 R2 and provide a simplified virtual hardware model and some additional functionality. You can only install a 64-bit operating system on a Generation 2 virtual machine. For more information. If the new virtual machine is configured as Generation 2 and will be running a Linux distribution, secure boot will need to be disabled. For more information on secure boot.
7. Select 2048 MB for the Startup Memory value and leave Use Dynamic Memory selected. Select the Next button. Memory is shared between a Hyper-V host and the virtual machine running on the host. The number of virtual machines that can run on a single host is in part dependent on available memory. A virtual machine can also be configured to use Dynamic Memory. When enabled, dynamic memory reclaims unused memory from the running virtual machine. This allows more virtual machines to run on the host. For more information on Dynamic Memory,
8. On the Configure Networking wizard, select a virtual switch for the virtual machine and select Next. For more information.
9. Give the virtual hard drive a name, select a location or keep the default, and finally specify a size. Select Next when ready. A virtual hard drive provides storage for a virtual machine similar to a physical hard drive. A virtual hard drive is required so that you can install an operating system on the virtual machine.
10. On the Installation Options wizard, select Install an operating system from a bootable image file and then select an operating system .iso file. Select Next once completed. When creating a virtual machine, you can configure some operating system installation options. The three options available are: Install an operating system later – this option makes no additional modification to the virtual machine.
    • Install an operating system from a bootable image file – this is similar to inserting a CD into the physical CD-ROM drive of a physical computer. To configure this option, select a .iso image. This image will be mounted to the virtual CD-ROM drive of the virtual machine. The boot order of the virtual machine is changed to boot first from the CD-ROM drive.
    • Install an operating system from a network-based installation server – This option is not available unless you have connected the virtual machine to a network switch. In this configuration, the virtual machine attempts to boot from the network.
11. Review the virtual machine details and select Finish to complete the virtual machine creation.
