Problem with early 2011 MacBook Pro. Circle with line

Im having trouble starting my MacBook Pro. I've been trying to troubleshoot the issue myself but am having no luck. When I turn on my laptop, it tells me to put in my password, then it tries to start up but changes to a circle with a line through it. I googled those symptoms and tried following some guides to reboot. Nothing seemed to work. I entered recover mode by restarting comp and holding command r. I attempted to reinstall mavericks so that I could restore using timemachine that I backed up a few days ago onto an external harddrive. When I goto reinstall mavericks, it only recognizes a partition that I made in my harddrive the other day. I suspect the issue I'm having is around this partition. When I launch disk utility the partition that I need to reinstall mavericks is not mounted and I'm not sure how to mount it. The other partition should be empty, I was trying to delete the partitons because I no longer needed them. (I originally wanted to dual boot ubuntu on mac but decided to just use a virtual box.) does anyone have any ideas about what I can do? If you need more info il try my best to help. Thanks

Some background infos:

- Mac mini (Late 2012), OS X Mountain Lion (10.8.5), Fusion Drive with 1TB HD + 128GB SSD

- TripleBoot with Mac, Windows and Ubuntu using rEFIt.

- The mac mini was running for weeks, or even months before. Was not turned off, only went to sleep. I noticed on my apple laptop that this can result in huge swap files in /private/var/vm/

- Before rebooting the system I tried to install the latest OS X version (10.9.4). After downloading the package, the installer asked me on which partition it should be installed. It didn't recognize the Ubuntu partition, which is totally fine. Bootcamp and Mac partition were found BUT BOTH WERE DECLARED AS UN-BOOTABLE. This surprised, I expteced at least my Mac partition as bootable. So I aborted the installation of 10.9.4 and tried to reboot. Which indeed didn't work and which is the situation I am currently in.
