I am having a problem using Grub2 to boot some bootable partition stored on a usb stick. Basically I am trying to fit several distros, all fat partitions made bootable with syslinux, on a usb stick and use grub2 to select and boot one of them. I should say that I come across two distinct cases, one using a GPT label and a much worse one employing the usual dos label. First I tried the gpt label cause I didn't relish the idea of using extended partitions. On a 8GB stick I create a BIOS Boot Partition, marked it with parted, and grub embedded itself in it with no problem. Then a second partition containing the configuration of grub, and further on several partitions containing distros, all fat16 bootable thanks to syslinux. I discovered, to my surprise, that grub allows me to boot only the third and fouth partition, while anyone beyond the fourth gives me boot error. I even created a fifth partition containing the exact same files of the fourth, and while the fourth boots, the fifth still doesn't. Then, on another stick, a 4GB one, I tried with a dos label. This time, after countless tries to get grub installed, and having succeeded, I discover that I can't boot any partition, even when having just two partitions, one with the configuration of grub and the other a bootable fat16 fs with a distro. I tried Grub legacy and it works fine. I tried chainloading Grub2 from Grub Legacy, just to make an attempt, and still no luck booting from Grub2. I have to specify the with booting one of the volumes I mean chainloading syslinux on it, doing a "chainloader +1" on the volume. The Grub 2 console works fine (it's brilliant by the way) but I can't chainload anything (with the GPT restricted exception detailed above. ) I compiled and run grub2 (from cvs and from git) on a Gentoo system running on a Macbook, and tested the sticks on 2 common x86 machines and with qemu with the same results. I figuratively beating my head against the wall, so any help or comment would be greatly appreciated.
P.S. I suppose I could just use Grub Legacy, but I just like Grub 2 immensely, so I'll keep that solution as a last resort, or maybe chainload Grub2 from Grub Legacy at least to use the shell.
