VHDX to VHD conversion

Recently I have started using Windows 8 to use Hyper-V on it.
Hyper-V on Windows 8 and Windows Server 2012 have new virtual hard disk format .VHDX which supports storage capacity of 64TB. You can download .VHDX format specification from here.
By default Hyper-V takes .vhdx format while creating virtual hard disk. And unfortunately Hyper-V on Windows Server 2008R2 and Virtual Box don’t support this format yet.
So here is the method of conversion from VHDX to VHD.

1) First you need to create virtual disk with extension .vhd. (I assume you have already a hard disk with .VHDX format)
2) Then go to New option Under Action section on right top box in Hyper-V >> Click on New >>
Select Hard Disk.
3) You will see below screen, Click on Next button


4)  Select VHD format and Click on Next button


5)  You can keep default option selected or change it Dynamic as per your need. Click on Next button.


6) Give name to VHD and go Next.


7) Select third option “Copy the contents of the specified virtual hard disk”.
and give your .vhdx drive path which you have to convert to .vhd format.


8) Click on Next button and this will copy your .vhdx content to your .vhd.
And VHD is ready to use on Virtual box, windows server 2008 hyper-v.
