Whenever I log into my computer I get a message telling me that there was an error. Also, a long time ago, grub stopped working. Whenever I booted my computer, it went straight into ubuntu, without going through grub first.

Why do you have the grub package installed? This is obsoleted in favor of grub-pc from grub2.
