I'm not very knowledgeable when it comes to burnng CD's and DVD's but I managed to rip a Windows 7 DVD to my hard drive succesfully.

I then made a copy of it and added an autounattended.xml file to it because I intend on creating my own set of recovery DVD's for a laptop.

I've added the iso succesfully but now I'm stuck on the part where I have to make the iso bootable. I have no clue what to do under Ubuntu. Ended up with ISO Master but I'm not sure why it insists that there is no boot image on the original ISO because there should be. (I was hoping it could "transfer" it to my newly made ISO but alas.)

So my question is: How do I make this ISO bootable so that I can run it like I would any other Windows 7 DVD?
