I have no recovery HD, tried installing Mavericks and now i can't acces lion either so I'm stuck with no OS.

Question

Hello, im really mad and desperate.
Was in lion and needed xcode 5 so I downloaded mavericks installer
Double clicked mavericks and began installation
I wanted to install over lion with no backups, had no important files already left.
Installation failed for some reason.
Now everytime i boot my mac, the os x maverick installer shows up, but i cant select lion (i have 3 disks available for install none of which are candidates, since one is bootcamp , im here now, and the others are disk04 and disk06 iirc)
I don't have recovery HD, when holding down option in boot I ONLY SEE MAVERICK OS X INSTALLER AND BOOTCAMP OPTIONS , i have tried cmd R, holding alt, etc and I CAN'T IN ANY WAY ERASE, RESTORE OR WHATEVER lion hd.
I was able however to boot lion in safe boot mode, but that's no use since its really slow and buggy. I need answers, I don't want to buy another HD for something that Apple advertises as "Just download and install" which completley ruined my mac.

Answer 1

In that case you can do Internet Recovery:
Install Mavericks, Lion/Mountain Lion Using Internet Recovery
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard drive.
Boot to the Internet Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.
Partition and Format the hard drive:
1. Select Disk Utility from the main menu and click on the Continue button.
2. After DU loads select your newly installed hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Partition button and wait until the process has completed. Quit DU and return to the main menu.
Reinstall Lion/Mountain Lion. Mavericks: Select Reinstall Lion/Mountain Lion, Mavericks and click on the Install button. Be sure to select the correct drive to use if you have more than one.
Note: You will need an active Internet connection. I suggest using Ethernet
            if possible because it is three times faster than wireless.
This will install Lion since that was the version pre-installed on your computer. From there you can upgrade to Mavericks.
