Assume a VirtualBox guest OS Windows 10 VDI disk image “mydisk.vdi” that you wish to mount without Virtualbox, perhaps because your guest OS crashed.
rescue files from crashed VirtualBox VDI.
VBoxManage clonehd --format RAW mydisk.vdi mydisk.img cd ~/"Virtualbox VMs/Windows 10" parted mydisk.img #not sudo unit B print
look for the “start” column for the biggest partition, that’s probably yours.
Let’s say you saw “12345 B” then type:
sudo mount -t ntfs -o loop,ro,offset=12345 mydisk.img /mnt
Now in your Linux File Explorer you can go to
/mnt and see the files.
It takes several minutes to unpack.
VirtualBox VDI Dynamic disk clone space utilization
The disk space used by the cloned
.img file will be the full expanded size of the dynamic partition if one was used.
So if your dynamic partition max size was 100 GB but only 10GB was used, the clone operation will still use the full 100 GB.
