first I'd like to state that the whole problem I have is with wanting not to change anything in the bios in order to boot ubuntu from another HD device.
alright, I think I can see the solution, I just don't quite know how to get it done.
I've installed Wubi into my external HD - a USB Device.
the image is there and all is good, one problem -
wubi did not update the NTLDR nor the already installed grub loader (wubildr*) with needed information on how to boot from the other HD.
the boot instructions I have there are relevant for the old wubi I've installed on that first internal HD.
when I try manually grub command like linux and initrd
I can only point to files located in any partition of my internal HD, like:
linux (hd0,1)/ ... or initrd (hd0,6)/ ...
there is nothing else, if I try "(hd1," and then press TAB nothing happens
it does not recognize that external USB HD.
which is very lame since I really want to be able to boot into that external HD without needing to reinstall that wubi into my first internal HD.
so I thought, maybe I can put the kernel/linux/initrd files in my first internal HD in a way that will allow grub to proceed with booting,
and then make it so that /etc/fstab will tell Ubuntu that root '/' is in that other secondary external USB HD.
but I'm really not sure how grub works as to what files exactly it needs to boot into a system that can process and finally work and understand /etc/fstab and then really boot the Ubuntu I know and love.
if you guys think of another, better or worse solution to my obvious problem I'd love to hear your thoughts since I think this isn't a trivial problem.
assistance would be greatly appreciated.
