I have almost convinced a family member to dual-boot with Ubuntu. I've showed him wubi, and he thinks that he's ready to give Ubuntu a try and dual boot. However, he thinks that overwriting the Windows bootloader is too risky and doesn't want to. I know you can restore the Windows bootloader after installation of Ubuntu, but that's not what I mean. Is there any option in the installer that I'm missing to skip installing GRUB? Thanks for any help in advance.
