I need to create an image to be able to mount the install DVD inside virtualbox in order to boot and install Windows.
Important: I need to do it using the command line.
I tried with genisoimage as suggested here and created an image using the command below but it turned out not bootable...
genisoimage -r -J -o cd_image.iso /cdrom
What I need is to RIP my original bootable DVD into a bootable IMAGE that I can mount in virtualbox.
So I thought I would ask how to A) convert that ISO file into a bootable one or B) re-create the ISO making it bootable with genisoimage or other command.
