Help I have no Recovery HD wont let me install Mavericks

.

My computer was doing the same thing, I took it to the apple store (after I backed it up), and they were able to add recovery & upgrade to 10.8 from which I can download mavericks and upgrade to current system. However, my computer is from 2007 and I am wary about upgrading to most recent software, 10.8 works plenty well for me! (for now...)

The problem is that OS X Mavericks requires a larger "Recovery HD" partition than "Mountain Lion" and "Show Lepard". The size of the "Recover y HD" volume for the earlier OS X(s) was something around 550 Mb. Mavericks requires more. I think it is around 650 Mb, but I have not found a reference from Apple about this.

Since I have come across this same problem I presume at this point that the OS X Mavericks installer tries to use the existing "Recovery HD" partition realizes that it is too small and then simply fails and gives as reference http://www.apple.com/support/no-recovery/ (The reference is far from helpful!)

Simply speaking the solution should be to size the current partition with the OS X install (usually "Macintosh HD") 1 Gb smaller and add this size to the "Recovery HD". This is (much!) simpler said then done.

Follow the following steps to accomplish this:

• By default "Disk Utility" does not show the "Recovery HD" partition. To allow "Disk Utility" to show this open Terminal and execute the following line:
  # defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

• Start "Disk Utility". A "Debug" menu should now be available that allows the selection for "Show Every Partition". This only partially helps as " Disk Utility" now shows all the partitions on the left under the <Harddisk>, but not in the "Partition" tab... (You can check if you want).
  
• Select the "Recovery HD" partition on the left and "Erase" it. This will clear the "Recovery HD" partition and change it into a normal partition. Now it will show in the "Partition" tab.
• Select the <Harddisk> and go to the "Partition" tab.
  
• Select the current (usually "Macintosh HD") partition. The size should show up on the right. Take this 1 Gb down and click Apply. This might take some time. This will resize the "Macintosh HD" partition to make more room for the "Recovery HD" partition.
  
• Select the "Recovery HD" partition and delete it (click "-").
  
• Click the "+" and create a partition called "Recovery HD". As soon as the "+" is clicked "Disk Utility" should create a partition in the space we re "Recovery HD" used to be, but ~1 GB larger. Change the name to "Recovery HD" and click Apply.
  
• Change the "Recovery HD" partition to an actual Recovery partition. Start Terminal
  # diskutil list
  (check for the /dev/disk#s# that has the label "Recovery HD")
  # asr adjust --target /dev/disk#s# --settype "Apple_Boot"

Now retry the OS X Maverics install...
