USB booting :: DSL Embedded + Ubuntu on USB?



Hello,

 I am wondering if this is possible:  I would like to be able to boot both Ubuntu and DSL 3.3 Embedded from BIOS, as well as use both from QEMU+KQEMU, with a partition for config files etc.  I realize GRUB will be neccesary,  but will both OS be able to reside in the one visible partition when on a Windows system?  Has this sort of thing been done before?  I want to be able to use this in the wild, and it would enable either OS to be used either way, depending on how fast the system was and whether it gave admin access or not.  Thanks.

I think it'll be possible.. But you can't use the partition from windows as it needs permissions for ubuntu..

I take this is for different machines? Will you have both Qemu for Win and KQemu for Ubuntu on that stick,
plus grub on the stick to choose between them?
My thought was as follows: four partitions.  The first one (visible to windows) containing both Ubuntu and DSL QEMU launchers, which will point to the partitions containing the images (if that is possible).  Otherwise, both Ubuntu and DSL in seperate directories with their own qemu launchers.  If the first option works, DSL and Ubuntu in their own partitions, with GRUB pointing to them with BIOS boot.  Final partition is file storage for both, formatted ext2 or ext3.  Only trouble is, is it possible to have QEMU launch from a seperate partition while in windows?  It is vital that both Distros be able to be launched while using any Windoze box in both ways (boot and QEMU).  Where would I start to make this happen?

Start by making & formatting the partitions:
sda1 - fat32 and sda 2 & 3 & 4 - ext3
Then install Ubuntu and DSL natively to ext3 partitions.. Don't use Ubuntu's grub, install from DSL manually to sda mbr (the script aint good for usb devices...)

Oh how big is the usb stick? I think Ubuntu alone takes 2gb :( .... DSL'll fit to 60mb..

Then tweak 'til you can boot both from BIOS usb chainloading grub..

Then put stuff from DSL-embedded to sda1 not including KNOPPIX, then tweak, tweak, tweak....
Thanks for the response.  It is a 4 gig cruzer, so no worries on the space.  Are there any pre-existing tutorials that I can dissect and mix to reach my eventual goals?  I know pendrivelinux has a few good ones, but it seems like I will need to do several things as you mentioned.  My biggest concern is, how do I get both OSs' visible to QEMU boot while on a bimbo-box Windoze system in the wild?  Since both DSL and Ubuntu will be on SDA(n+1), and therefore invisible to W$n, how does that work?  I realize this is a self-teaching forum, and I hate to even be asking this many questions, but I feel like this may be a rather rare configuration I am shooting for.  Can syslinux be used to chainload, or is GRUB still the best bet?  Theoretically, can more than 2 (3, 4?) OSs be booted with QEMU while on a bimbo-box in the wild?  I look forward to more responses, thank you so far.
