Can I set up my computer to boot from multiple hard drives?

Just to make sure I understand correctly, when you say the Ubuntu drives will pick up the OS's on other drives, you're not saying it will actually transfer files, right? It just shows up on a Grub menu?

Right. The other operating systems would just show up on the Grub menu, and you would have a choice to start them up, or start the one on the disk you booted into. If you want to boot directly to the OS on the disk without the grub menu showing, you have to disable the OS prober, which could be done later after you install. This will stop the menu appearing.

Ok, in that case I won't worry about it. Thanks!
