I've been googling for an answer and can't find the exact one I want...

My computer doesn't allow booting from a usb device, and I have dsl on a thumbdrive and it just doesn't boot, that's fine.

I do have xubuntu on this computer, and grub is installed to boot that. Is there any way that I can edit menu.1st to point to the OS on my usb thumbdrive? I can't find anything on this subject.

I know you can install grub onto the thumbdrive, but I would guess it would also have to be able to boot by the computer anyways, which mine does not.

Thx!

Yeah, that's possible.

You would only install grub on the thumb drive if it could boot, correct.

To have an option in your desktop grub, you can:

copy the kernel and minirt24.gz to your HD, and let them find the data on the stick (you can also boot DSL from your HD and cd and pcmcia cd and zip drive etc. this way, by having only the data on it)

Since grub doesn't have usb code, it cannot boot it directly..

For the entry do something like this, changing parts for your needs:

title DSL from usb stick
root(hd0,0)
kernel /boot/linux24 ..insert the DSL options you want here, get from isolinux.cfg for example..
initrd /boot/minirt24.gz

Using "fromusb" might help here.

It's not needed, as all drives are scanned by default..
