convert a vhd to vdi

[sjj1805]

To convert a vhd to vdi:

If the vhd is not fixed-size, make it so, using Virtual PC's disk wizard

Start VirtualBox

Move the virtual disk to the \"Virtual Box\" Program Directory
M:\\Program Files\\Sun\\xVM VirtualBox

Open a CMD prompt and navigate to the \"Virtual Box\" Program Directory
M:\\Program Files\\Sun\\xVM VirtualBox

Code: Select all

vboxmanage convertdd the_disk.vhd the_disk.vdi

Make the vdi dynamic:

Code: Select all

vboxmanage modifyvdi the_disk.vdi compact

Note: ideally, you should delete (or exclude) the last 512 bytes of the vhd file before using convertdd, but it still works fine if you don't (the vdi disk will have an extra sector.)
