After some trouble with installing Ubuntu (the automatically installation actually installed to an external hd without my knowledge), I finally made it working yesterday by makeing partitions myself and run the manual installationprocess. I can now boot both Ubuntu and Windows.

But; When I manually chose the installationpartitions, I missed on the bootloader - which I placed in a wrong hd... That means that I now have to go into bios and choose that drive every time I want to boot into Ubuntu.

I know I should reinstall, but is there a (simple) way to move that bootloader and merge it into the one on my systemdrive without loosing the opportunity to dualboot?
