I'm using VirtualBox in Ubuntu. I have an existing Windows 10 partition, I created a VMDK file like below, following the instructions from How to use a real partition with Windows 7 installed, in a virtualbox vm?
sudo VBoxManage internalcommands createrawvmdk -filename Win10.vmdk -rawdisk /dev/sda -partitions 1,2,3,4,5
Then imported it to VirtualBox.
But when I run that VM, it is getting me into grub rescue command screen by showing error: unknown filesystem. How can I proceed?
