Although a lot of people want you to begin with the second option and although it's a good thing for an hipothetical super grub2 disk...

That's how it works in Grub legacy I suppose. Nope. This is a different thing. This is a new feature which is not present in GRUB Legacy. Although people often mistake this, booting a CD from GRUB is quite different from booting a GRUB installed into a CD. GRUB Legacy has the latter feature, but not the former one. GRUB 2 needs to support both cases, but I prefer to see something not present in GRUB Legacy implemented in GRUB 2 first. ======= But do as you want, maybe it is better to begin with the easiest task and then doing the more difficult task. adrian15
