grub2

I installed Ubuntu on my external hard drive but it won't boot on my laptop. what do i do? i did some reading and traced the source of the problem to grub2. Apparently, grub2 doesn't use the device's UUID, and uses the linux directory instead (/dev/sdf2). This means that whenever i plug my E-HDD into a system that has a different number of drives connected to it, i won't be able to boot without editting the boot command. I don't understand it too well but that's what i got from what i read. Is there anyway to fix this?
