I recently heard about Ubuntu and was excited to try it out. However, I seem to have made a bad decision. I installed it successfully the first time, but then the grub/boot menu wouldn't come up. It would just go straight to Windows, like Ubuntu wasn't even there (even though I am sure it was installed). Anyways, I decided I would go back in to the Ubuntu installation using my flash drive (the "try Ubuntu" version) and I selected the option where you can uninstall Ubuntu and then re-install. After I did this, the boot menu still didn't work--BUT the terrible thing is instead of going to Windows, it goes straight to Ubuntu without giving me an option! And on my computer's boot menu (I press F12 to get to it) there are two options: Ubuntu and Ubuntu! I am so confused and mortified. Did I somehow erase Windows 8? Please help! Thanks in advance.
