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 ?
