I've been trying to boot my Windows 8.1 on a VirtualBox machine under my Linux Mint 17. Everything is in x64. I've installed VirtualBox and its GUI to do so. My Windows 8.1 is on /dev/sda2, my Mint 17 on /dev/sda3.

I'm using the command : VBoxManage internalcommands createrawvmdk -filename ~/.VirtualBox/Eight.vmdk -rawdisk /dev/sda -partitions 2

Which gives back : VBoxManage: error: Cannot open the raw disk '/dev/sda': VERR_ACCESS_DENIED [...]

I'm using http://www.qc4blog.com/?p=483 and Use VirtualBox to boot a physical drive/partition to get it.

There are many thing said on the net regarding this error. But I'm lost in the middle of them. What should I do to achieve my goal ?

2 things immediately come to mind:

1 Are you running this as root or sudo ? This is needed for raw access to the disk.
2 Make sure /dev/sda has NONE of it's partitions mounted in Mint. You need VirtualBox to be the ONLY process that accesses the disk on the host OS.
