I have a dual-boot laptop with Windows 7 and Ubuntu 12.04. I am trying to boot the ubuntu partition from windows using Virtualbox. I have successfully created the .vmdk, and created the virtual machine. However, I can't get it to boot (in Virtualbox). All I get is a black screen with the cursor in the top left.
I wonder if I'm specifying the partitions correctly. My Ubuntu install has 3 partitions: \, \boot, \home. No swap partition. These are all in Disk 0, partitions 3,4,5 respectively.
The command I used to create the .vmdk is:
VBoxManage internalcommands createrawvmdk -filename C:\Users\abalter\.virtualbox\ubuntu.vmdk -rawdisk \\.\PhysicalDrive0 -partitions 3,4,5
Then I create a virtual machine based on that .vmdk.
Why won't it boot?
1I'm not sure what you mean by custom ISO. Could you explain? I've gotten it to work with a USB drive with no custom ISO. – abalter – 2012-07-07T04:21:51.420
The purpose of the custom install ISO is to include programs that put the grub2 partition inside the linux partition.
Instead, putting Linux on its own disk (for your case a USB stick), also works since the problem is with windows and linux on the same disk. – cagney – 2013-03-11T17:42:49.787
