During the boot process (when using the installation DVD) or after a full boot, run disk utility and, having selected the main partition with the system in it, we perform a disk check in order to find out if everything is in order with the structure of the disk file system. We restart the computer, but we do not boot as usual, but from the recovery disk or from any other bootable volume (installation DVD, backup copy of the main partition, etc.). With proper user skill and experience in assembling and disassembling your Mac, you should regularly clean its insides from dust. Prevention of hardware by the user consists in working with PRAM and PMU settings, disk boot volume data and partition table structure. We want to warn you right away that not all of the tips below should be used in any case - some of them are recommended only for obvious problems. We will talk about this in today's article. Mac OS X contains many various settings and temporary elements, both at the software and hardware levels, that can affect the operation of the system as a whole and individual applications.

Please do not answer this question if you don't understand the difference between "Apple Hardware Test" and "Apple Diagnostics."

I can now boot into recovery mode, but I still have the problem described above.
Re-downloading and re-installing Mavericks fixed this problem. After the transfer, the laptop worked fine, but would not boot into recovery mode- holding down option at startup and selecting the recovery drive yielded a grey screen with a white, cross-out circle in the middle. Some more background: This is a new macbook pro, and I copied the hard drive from my old one using disk utility. How do I replace the "Apple Hardware Test" firmware program with the "Apple Diagnostics" firmware program? When I try to run in, it fails, saying my hardware is not supported. However, "Apple Hardware Test" comes up instead. According to this article, holding down the "D" key while my MacBookPro11,3 boots should bring up "Apple Diagnostics".
