The purpose of this tutorial is to enable you to create a password reset disk for your Windows Server 2012 virtual machine, installed on a Windows Server 2012 Hyper-V virtualization server. This disk is to be used in case your virtual machine’s password is lost.
IMPORTANT: You must have access to the virtual machine (correct password) in order to be able to create the backup disk which you will use to reset the account’s password in case it is lost.
Here are the steps to follow.
1- Connect via Remote Desktop to the physical server on which Hyper-V is installed.
2- Launch the interface for "Hyper-V Manager" from the "Start" menu or from "Server Manager".
3- To create a virtual floppy disk, click on New > Floppy Disk ...
4- Specify the file location for the virtual floppy disk, choose a name, and click the "Create" button.
5- From “Hyper-V Manager”, launch the console of the virtual machine for which you are creating the password reset disk.
To do this, simply double-click on the virtual machine’s name.
6- Click on Media > Diskette Drive > Insert Disk ...
7- Select the file you created in Step 4 above, then click "Open".
8- Connect to your Windows 2012 virtual machine from the Hyper-V Manager console, using the correct password.
9- Format the virtual "floppy disk" you inserted in Step 7 above.
From Windows Explorer.
Click on "Computer", then right-click on "Floppy Disk Drive (A:)" and then on "Format ..."
Click "OK" to format the disk.
Click "OK" to close the information window once the operation is complete.
You may now close the Windows Explorer window.
