I am trying to get lion 10.8.2 working on virtual box under ubuntu 12.04 host.

I have the dmg file and I have the amd_kernel downloaded from http://www.osx86.net...ion_10.8.2.html

Now I think I need to get the amd_kernel file into the dmg but I dont know how to do this.

After quite some research, I was able to dump the contents of the dmg into a directory (using acetone iso) and I copied amd_kernel onto it. Now I tried to make an iso out of this folder but virtual box says no bootable medium found

So essentially I need to know how to create a bootable iso from a folder.

I have really been struggling with this for hours, so please help me out.
