Sector repair attempts to repair the sectors - but as I stated, you may lose files/data because of it. It attempts to rewrite the data back to the sector in an attempt to repair it - if it's not able to repair it, then it marks it as bad and moves on to the next block.
In this case, since it doesn't boot, I'd suspect that the beginning sectors on the disk were what was repaired.
Will the Startup Repair work now? Give it a try and let us know the results (if any).
The DFT tests your physical hard drive. This doesn't account for any of the file system stuff on the hard drive, nor does it account for Windows.
Startup Repair tests the file system stuff on your hard drive (along with some other tests). It's the fix of choice for these sorts of errors. It can fail for many different reasons - but the most common is a bad hard drive. When the DFT asks you if the list of devices is correct - please jot down the numbers there and post back with that info (it's usually enough info for us to identify your drive). Once we find the drive make and model, we can recommend a more specific test for your hard drive. I refer people to the manufacturer of the hard drive because the manufacturer usually builds in extra stuff that only their diagnostic can read.
Also, it's not just the hard drive that can fail. One example is a failure of the device (on the motherboard) that controls the hard drive. This will give similar symptoms, but won't be revealed by a hard drive test. In those cases I recommend the SeaTools by SeaGate because their test includes a Hard Drive Controller test.
