In two days I'm going to dual boot my Windows box with Ubuntu.
I use the Windows machine *only* for gaming, so I don't think I have any data on there that I care about.
What am I going to regret not backing up?
It's the right order. If you install Windows after Ubuntu it would be much harder -- Windows doesn't see Linux filesystems and wipes out the bootloader.
Ubuntu will see Windows and likely it will offer to put it into the boot menu.
Good luck!
@swordplay That's reassuring!
My machine happens to have two hard drives, so at least I get to avoid partitioning.
@peterdrake
Linux installs have generally gotten really good. Do it a couple of times and it's merely a task.
If you know about partitioning, you should be okay.
Aloha!
