Answers: command line - VBoxManage: error: Cannot read the partition information from '/dev/disk0'

I'm trying to make a partition .vmdk file for Virtual Box. Basically I want to boot my bootcamp partition box up in Virtual Box. But I get the following error when I try to make the .vmdk file

VBoxManage: error: Cannot read the partition information from '/dev/disk0' VBoxManage: error: The raw disk vmdk file was not created

Here's the exact sequence of commands I typed in terminal

sudo chmod 0777 /dev/disk0

sudo chmod 0777 /dev/disk0s4

sudo VBoxManage internalcommands createrawvmdk -filename WinXP.vmdk -rawdisk /dev/disk0 -partitions 4

VBoxManage: error: Cannot read the partition information from '/dev/disk0' VBoxManage: error: The raw disk vmdk file was not created

partitioning - Grub Setup(hd0) Error Cannot mount selected partition

partitioning mount ntfs grub setup

MA1

I have created a NTFS Partition(/dev/sda3) and copy the grub files in it in the following path: /dev/sda3/boot/grub/

then tried to install the grub by using following commands:

grub> root (hd0,2)

 Filesystem unknown, partition type 0x7

grub> setup (hd0)

 Error : cannot mount selected partition

The partition is present and i created it with gparted.

i also tried the following command:

find (hd0,2)/boot/grub/stage1

Error 15: File not found

All the files were there as copied them. So, where is the problem and what i am doing wrong?
