So, all this stuff happened, and I managed to reinstall Ubuntu alongside Windows 7, but for some reason it just skips the Grub2 menu and goes straight to Ubuntu. I did a sudo update-grub2, and these were the results:
coleman@coleman-Aspire-Z5101:~$ sudo update-grub2
Generating grub.cfg ...

And if it's any help, here's my boot info:
